Taste of Congress Tour more info
Visit four of Congress Street's best restaurants over ONE evening. Meet the creators of the food that are putting Portland, Maine on the national food map. Meeting place will be announced by email, 48 hours before the event.
Share Tastes of Congress Tour
Portlanders are lucky to have such great restaurants to explore. National media sources are constantly writing about the remarkable quality of food that comes out of such a tiny city. Nowhere is this quality more exemplified than in the restaurants that line Portland's Congress Street.
Located further away from the typical tourist stops, these restaurants have to produce the kind of food that will make locals want to return time and time again. Join Portland Taste Tours as we stop at four of these great spots to sample their food and get to know the chefs behind them.
We'll be meeting at 7 pm at MJ's Wine Bar at One City Center, and finishing Further up Congress Street at Oak Street, to keep in mind for parking.
Please keep checking our website at www.portlandtastetours.com as we'll be scheduling tours for various dietary needs in the future.
Parking is on street, but it's after 6pm so you don't have to feed the meters!
This is a walking tour, so wear shoes you are comfortable standing and walking in. As for attire, wear whatever you feel comfortable going out to dinner in.
Drinks are outside of the ticket price. We encourage guests to use cash to keep the momentum of the evening going.
Gratuity for food is included in the ticket price. You are welcome to add to that if you are satisfied with your experience.
Tickets may be refunded up to 48 hours before the event date.

US 6369453 B1Abstract
A method and semiconductor wafer is provided for measurement and recordation of hydrophilic elements in semiconductor insulators by depositing a moisture barrier layer over a previously deposited insulating layer of a semiconductor wafer. The semiconductor wafers become pilot or calibration wafers which may be placed immediately in an infrared radiation instrument to allow measurement of the concentration of hydrophilic elements in the insulating layer or stored for recordation purposes and measured later.
The invention claimed is: 1. A semiconductor wafer comprising:
an unprocessed semiconductor wafer; a silicate glass insulator on the unprocessed semiconductor wafer, the silicate glass insulator containing a hydrophilic element; and a moisture barrier material on the silicate glass insulator. 2. The semiconductor wafer as claimed in claim 1, wherein the silicate glass insulator contains a hydrophilic element selected from a group consisting of boron, phosphorus, and a combination thereof.
3. The semiconductor wafer as claimed in claim 1 wherein the moisture barrier material is ultra violet silicon nitride with a Refractance index of 1.915.
4. The semiconductor wafer as claimed in claim 1, wherein the moisture barrier material is silicon nitride with a thickness less than 250 Å.
The present invention relates generally to semiconductor manufacturing and more specifically to a method for accurate measurement and recordation of boron and phosphorus caused impurities in semiconductor insulator layers.
Silicon compounds, such as silicon dioxide (SiO2), that can be used as insulators are particularly valuable on electronic substrates. Such insulators serve as protective coatings, inter-layer dielectric layers, doped dielectric layers to produce transistor-like devices, multilayer devices, etc.
Unfortunately, development of high integration and high-density very large-scale integrated circuits has progressed so rapidly that earlier silicon (Si) compounds have become less than satisfactory. To meet the recent needs of miniaturization of high-density semiconductor devices, a technique of forming a flat insulating layer under low temperature conditions, which utilizes flow on silicate glass, has started to come into use.
Silicate glass is easily flattened and makes a good insulating layer. Thus, silicate glasses such as borophosphotetraethylorthosilicate (BPTEOS) and borophosphosilicate (BPSG) glass have come into use.
Typically, the silicate glass is deposited in a spin-on deposition process in a liquid form in a nitrogen atmosphere. The silicate glass is then subjected to thermal treatment to allow for proper planarization and stress relief. Without the thermal treatment, incorrect concentrations of the boron (B) and phosphorus (P) elements will result in a non-planar surface and stresses, which can lead to de-lamination, and flaking of subsequently deposited layers.
One problem with boron and phosphorous is that they are hydrophilic (attract water) elements and they start to form precipitates immediately after deposition of the silicate glass. These precipitates may cause short-circuiting of the electrical interconnections, which are later formed on the silicate glass.
This has not been a major problem during semiconductor fabrication because the processing, which includes the formation of contacts, interconnects, and vias are performed in a nitrogen atmosphere.
However, during pilot or calibration runs, pilot (dummy) or calibration wafers are run through an insulator deposition machine and then are measured in air under an infrared radiation instrument to obtain the concentrations of both boron and phosphorus prior to going into production operation. Such measurement instruments as the BIO-RAD instrument from Bio-Rad Laboratories, Inc. at 237 Putham Ave. in Cambridge, Mass., are used.
Also, pilot wafers are run after the deposition machine undergoes any type of maintenance. Further, these pilot wafers may be kept for substantial periods of time in order to maintain traceability records of the production runs, which used the pilot wafers, in the event of any problems further down in the production line or out in the field.
It has been found that the insulator on pilot wafers absorbs moisture from the air as an unpredictable function of time and humidity. The absorption of moisture results in false measurements and leads to incorrect determination of the boron and phosphorus concentrations depending on how long after production the pilot wafer is measured.
It has also been noted that the calibration wafers used for the infrared radiation instruments also absorb moisture which means that the calibration standards are sometimes inaccurate and adversely affect subsequent measurements.
In the past, when these problems arose, the wafers were sent to an external laboratory for validation where the precise amount of moisture and concentration of the hydrophilic elements could be analyzed.
Unfortunately, such procedures could not give real-time measurements and were time consuming. Further, sometimes the precipitates were in the original silicate glass deposition rendering the readings inaccurate because a determination could not be made of when the precipitates were formed and thus, the true source of the precipitates. Without knowing the true source of the precipitates, the actual boron and phosphorus concentrations of the silicate glass deposited could not be determined.
As the density of semiconductor devices increases, the problem caused by impurities at lower and lower levels becomes quite substantial and a need to solve the problems related to the element caused impurities become more pressing.
The present invention a pilot or calibration semiconductor wafer having a silicate glass insulator containing a hydrophilic element for measurement or recordation purposes. The semiconductor wafer has a moisture barrier, test transparent material on the silicate glass insulator and can be placed in a moisture containing atmosphere without affecting the concentration of the hydrophilic element. The semiconductor wafer can be stored and measurements taken later to accurately determine the concentration of the hydrophilic element in the silicate glass insulator.
The present invention further provides a method for processing a pilot or calibration semiconductor wafer having a silicate glass insulator containing a hydrophilic element for measurement or recordation purposes. The method includes depositing the silicate glass insulator onto the semiconductor wafer followed by the deposition of a moisture barrier, test transparent material onto the silicate glass insulator in a non-moisture containing environment. The semiconductor wafer can be placed in a moisture containing atmosphere. The measurement can be performed immediately or the semiconductor wafer can be stored and measurements taken later to accurately determine the concentration of the hydrophilic element in the silicate glass insulator.
The present invention further provides a method for processing a pilot or calibration silicon wafer having a BPTEOS or BPSG silicate glass insulator containing hydrophilic elements, such as boron and phosphorus, for measurement or recordation purposes. The method includes depositing the silicate glass insulator onto the silicon wafer followed by the deposition of a moisture barrier, test transparent material, such as an ultra-violet transparent nitride, onto the silicate glass insulator in a nitrogen containing environment. The semiconductor wafer can be placed in air. The measurement can be performed immediately or the semiconductor wafer can be stored without special precautions and measurements taken later to accurately determine the concentration of the boron and phosphorus in the silicate glass insulator.
FIG. 1 is a cross-section of a portion of a multilayer semiconductor device according to the present invention;
FIG. 2 is the cross-section of the chemical vapor deposition equipment used in the present invention for processing a pilot or calibration semiconductor wafers; and
FIG. 3 is a schematic of a semiconductor wafer in an infrared instrument for determining the concentration of hydrophilic elements in the processed semiconductor wafer.
Referring now to FIG. 1, therein is shown a portion of a semiconductor wafer 10 including a semiconductor substrate 12 and a planarized insulating layer 14. It will be noted, as will subsequently be explained in detail, that the semiconductor wafer 10 is either a pilot semiconductor wafer or a calibration semiconductor wafer and, in either situation, does not have electronic semiconductor devices either in or on it. Deposited on the insulating layer 14 is a moisture barrier layer 16.
The semiconductor substrate 12 is generally of doped or undoped silicon and the insulating layer 14 is of a silicate glass. Silicate glasses are preferred for their ability to be deposited at low temperatures below 400� C. and for their self-leveling properties which make subsequent planarization and deposition of subsequent layers of material easier. Examples of this type of silicate glass are borophosphosilicate glass (BPSG) and borophosphotetraethylorthosilicate (BPTEOS) glass. The two exemplary silicate glasses contain hydrophilic elements boron (B) and phosphorus (P), and other silicate glasses contain either one or the other which absorb moisture and form precipitates which could cause short- circuits in production semiconductor wafers which have semiconductor devices and interconnections embedded in the insulating layer 14.
The moisture barrier layer 16 is selected from the group of materials which are moisture proof and are also transparent to the mechanism of testing. of a protective material commonly used in semiconductor processing, such as silicon nitride (SiN). Based on experimentation, it has been determined that the silicon nitride needs to be between 150 to 350 Angstroms (Å) thick, with the optimum at 250 Å. It has been determined that without the moisture barrier layer 16, the precipitate count begins to increase immediately and continues to increase past 35 days. Conversely, with the moisture barrier layer 16, the change in the precipitate level is negligible past 35 days.
Referring now to FIG. 2, therein is shown chemical vapor deposition equipment 110 consisting of a chamber 112 containing a hot plate carrier 114 for supporting the semiconductor wafer 10. The semiconductor wafer 10 is heated by heat lamps 116 or the hotplate carrier 114 in a nitrogen atmosphere provided by a gas source 120. The gas source 120 is capable of providing a plurality of different gasses. The chemical vapor deposition equipment 110 is provided with a pump 118 for pumping gasses out of the chamber 112 and an insulating material source 122 for providing fluid insulating material to a nozzle 124.
Referring now to FIG. 3, therein is shown the semiconductor wafer 10 in an infrared radiation instrument 130 such as the BIORAD tester by Bio-Rad Laboratories, Inc., 237 Putham Avenue, Cambridge, Mass. 02139. In the infrared radiation instrument 130, the concentration of hydrophilic elements, such as boron and phosphorus, is determined.
In the operation of the present invention, the insulating layer 14 is deposited on the semiconductor wafer 10 in the chemical vapor deposition equipment 110 from the insulating material source 122 through the nozzle 124 in a nitrogen atmosphere provided by the gas source 120. The semiconductor wafer 10 is then subject to thermal heat treatment in the nitrogen atmosphere in the chamber 112 to cause glass-flow planarization of the insulating layer 14 using the heat lamps 116 and/or the hot plate carrier 114.
Subsequently, the chemical vapor deposition equipment 110 can allow the entry of various precursor gasses from the gas source 120 to cause the deposition of a moisture barrier material, such as ultra violet (UV) silicon nitride (Si3N4) with a Refractance Index (RI)=1.915. UV silicon nitride is an ideal since it is moisture proof and is transparent to infrared radiation in the range used by the BIORAD tester when properly formulated.
It has been discovered that the UV transmittance depends on the percentage of siliconhydrogen bond in the UV silicon nitride that absorbs UV light. The UV transmittance is measured directly and the percentage of the silicon-hydrogen bond controlled by adjusting the temperature of deposition to maintain the UV transmittance at 20% to 30%, which is the transmittance acceptable to the BIORAD tester. In the best mode, the UV silicon nitride is deposited to a thickness under 250 Å for wafers for sub-0.18 micron critical dimension semiconductor devices.
In semiconductor fabrication, the sample semiconductor wafer 10 which is used to test the process is referred to as a “pilot” wafer. It carries no semiconductor devices. Also, a pilot wafer is used as the first wafer through whenever the equipment for depositing the insulating layer 14 undergoes periodic maintenance.
Since the processing for a single batch of wafers can take between 6 to 10 weeks and sometimes a production run will last for an extended period of time before changing any of the process parameters, it is often desirable to store pilot wafers for recordation purposes so that if later problems are detected, the original characteristics of the insulating layer 14 can be re-examined. Thus, it is desirable that the storage may be accomplished without having to have the silicon wafers 10 stored under special conditions in a moisture free atmosphere. The moisture barrier layer 14 provides sufficient protection for the necessary record keeping time.
Further, the silicon wafer 10 with the moisture barrier layer 16 is sufficiently stable that it can be used as a hydrophilic material standard for calibrating the infrared radiation instrument 130. In this situation, one of the silicon wafers 10 is used as a standard and no external laboratory validation is required.

Skelton is more durable. He has shown greater resourcefulness in fourth quarters, helping the Cardinals to five fourth-quarter comeback victories.The backup plan arguably looks better if Kolb wins the starting job.Skelton and Kolb each own five career games with at least 270 yards passing. Skelton passed for 282 yards with three touchdowns and two interceptions in coming off the bench to help the Cardinals to an upset victory over San Francisco last season. He made key plays by air and ground during a Week 17 victory over Seattle, completing third-down passes for 26, 26, 22 and 18 yards.Skelton has done more to earn the team's confidence as a backup and possibly even as a starter. The Cardinals can feel relatively good about their backup QB plan either way.Confidence rating (out of 100) if Kolb or Skelton is out for extended period: 60.

I needed pillows that were firmer than I had on my bed, which were practically like sleeping with nothing. These pillows are very well made-a little too firm for my taste, but definitely for someone who likes a little elevation of the neck when sleeping.
I bought these for my daughter going to college. They were great--fluffy but not stiff.
These are ok - you basically get what you pay for - may be better off going to the store
Great firm pillows, just what i was looking for!! Great pricing, fast delivery!!
I received these pillow but it's standard pillows ,I want king size unfortunately I have to return these to get the king size but other then tat very firm which I wanted !
Upon arrival,, one of the pillows was missing thread at the zipper. these were to be gifts for my nephews, but they will be returned instead.
lorusquartz
I don't usually write poor reviews for products but I was SO disappointed in these pillows. In one week they went flat. I had to roll the corners to fluff the pillow in the middle. No neck support even though these are gusset pillows. No substance to these. You can find better pillows at Walmart for less. I really like Overstock and usually the ratings are spot on, but not this time.

1. OVERVIEW 1. INTRODUCTION TO SATELLITE SYSTEM 2. CLASSIFICATION OF ORBITS a) GEO b) MEO c) LEO 3. IRIDIUM SKETCH & NETWORKING 4. GLOBALSTAR SKETCH & NETWORKING 5. ICO CONCEPTS 6. COMPARISION BETWEEN IRIDIUM, GLOBALSTAR, & ICO 7. CONCLUSION 8. REFERENCE
2. INTRODUCTION TO SATELLITE SYSTEM  A Satellite is something that goes around and around a large something, like the earth or another planet.  Some satellite are natural , like the moon ,which is a natural satellite of the earth . Other satellite are made by scientists and technologists to go around the earth and do certain jobs.  Some satellites send and receive television signals.  The signal is sent from a station on the earth’s surface.  The satellite receives the signal and rebroadcasts it to other places on the earth
3. WHY SATELLITE????  To avoid number of repeaters on the earth surface.  Avoiding line of sight propagation .  High coverage area i.e. a single satellite covers 48% earth surface . For this we require 3 satellites to cover the total surface.  To avoid obstacles like building , tree , mountain etc.  Instant communication.  To cover remote areas.  Increase data transfer rates.
4. CLASSIFICATION OF ORBITS 1)Geostationary (or Geosynchronous) Earth Orbit(GEO) 2)Medium Earth Orbit(MEO) 3)Low Earth Orbit(LEO) 4)Highly elliptical orbit(HEO)
5. GEO  GEO satellites have distance of almost 36000km from earth  Orbital period equal to earth’s rotational period(one day), so this appear motionless respect to earth.  Communication satellite & weather satellite are given this orbit. Orbital velocity 3.07km/s(1.91mi/s)
6. MEO  Known as Intermediate Circular Orbit(ICO).  Altitude is between 2000km to 36000km.  Orbital period range from 2 to 24 hours.  Satellites are mostly used for navigation, communication and geodetic/space environment science.  EX:- 1)Global Positioning System (20200Km altitude) 2)Golonass (19100Km altitude) 3)Galileo (23222 Km altitude)
7. LEO  Extends from the Earth’s surface at sea level to an altitude of 2,000 km.  Orbit times are much less than for many other forms of orbit.  Some speed reduction may be experienced as a result of friction from gasses, especially at lower altitudes.  Altitude of 300 km is normally accepted as the minimum for an orbit as a result of the increasing drag from the presence of gasses at low altitudes.  Used for both military & aeronautical purposes
8. WHY IRIDIUM ????  Contains 77 satellites.  Named IRIDIUM after element Iridium with atomic number 77 and the satellites evoking the Bohr’s Model of electrons orbiting around the Earth as its nucleus.  The constellation of 66 active satellites has 6 orbital planes spaced 30 degrees apart, with 11 satellites in each plane.
9. SKETCH OF IRIDIUM SATELLITE
10. ABOUT IRIDIUM NETWORK  Iridium system is a satellite-based, wireless personal communications network providing voice and data features all over the globe.  It is comprised of three principal components 1. the satellite network 2. the ground network 3. Iridium subscriber products, including phones and data modems
11. WORKING OF IRIDIUM NETWORK  Iridium network allows voice and data messages to be routed anywhere in the world.  Voice and data calls are relayed from one satellite to another until they reach the satellite above the Iridium handset or terminal and the signal is relayed back to Earth.  When an Iridium customer places a call from a handset or terminal, it connects to satellite overhead, and the signal is relayed among satellites around the globe to whatever satellite is above the appropriate Earth gateway, which downlinks the call and transfers it to the global public voice network or Internet so that it reaches the recipient.
12. GLOBALSTAR(the sketch)
13. GLOBALSTAR  Globalstar is a Low Earth Orbit(LEO) satellite constellation for satellite phone and low-speed data communications.  Globalstar orbits have an inclination of 52 degrees. Therefore, Globalstar does not cover polar areas, due to the lower orbital inclination.  Globalstar orbits have an orbital height of approximately 1400 km. .
14. 2nd Generation GLOBALSTAR SATELLITE  New Globalstar second-generation satellite is three- axis stabilized spacecraft consisting of a trapezoidal main body with two solar arrays.  The second–generation architecture has emphasized on redundancy management and the radiation environment of the Globalstar operational orbit.  Each second-generation Globalstar satellite 1. weighs approximately 700 kgs. 2. offers power of 2.4 kW . 3. Fitted with 16 transponders from C-to S-band, and 16 receivers from L- to C-band.  The satellite’s body is fabricated from rigid aluminum honeycomb panels.
15. 2nd Generation GLOBALSTAR SATELLITE  The satellites were designed to operate in the 920-km orbit with the inclination 52 degrees toward the Equator.  Uses sun sensors, Earth sensors, and a magnetic sensor to help maintain attitude.  Utilizes thrusters for orbit-raising, station-keeping maneuvers and altitude control.  Two solar arrays provide the primary source of power, while batteries are used during eclipses and peak traffic periods. The solar panels automatically track the Sun as the satellite orbits the Earth, providing maximum possible exposure to the solar energy.
16. 2nd Generation GLOBALSTAR SATELLITE  Heart of a Globalstar satellite is its communications systems.  There are C-band antennas for communications with Globalstar gateways, and L- and S-band antennas for communications with user terminals.  The advanced constellation provides Globalstar customers with enhanced future services 1. Increased data speeds of up to 256 kbps in a flexible Internet protocol multimedia subsystem, IMS, configuration. 2. push-to-talk and multicasting. 3. advanced messaging capabilities such as multimedia messaging or MMS. 4. geo-location services. 5. multi-band and multi-mode handsets 6. data devices with GPS integration.
17. WORKING OF GLOBALSTAR SATELLITE  Several satellites pick up a call, and "path diversity" helps assure that the call is not dropped even if a phone moves out of sight of one of the satellites.  a second satellite picks up the signal and is able to contact the same terrestrial gateway, it begins to simultaneously transmit. If buildings or terrain block your phone signal, this "soft-handoff" prevents call interruption. The second satellite now maintains transmission of the original signal to the terrestrial "gateway".  Gateways process calls, then distribute them. But if there are no gateway stations to cover certain remote areas, service cannot be provided in these remote areas, even if the satellites may fly over them.

19. ICO  Known as Medium Earth Orbit(MEO).  Altitude is between 2000km to 36000km.  Orbital period range from 2 to 24 hours.  Consist of 10 active satellite.  Satellites are mostly used for navigation, communication and geodetic/space environment science. EX:- 1)Global Positioning System(20200Km altitude) 2)Golonass(19100Km altitude) 3)Galileo(23222 Km altitude)  The satellites will communicate with terrestrial networks through the ICONET, a high-bandwidth global Internet Protocol (IP) network.
20. CONCEPT OF ICO The ICO is a MEO mobile satellite system, is designed primarily to provide services to handheld phones. ICO will use TDMA as the radio transmission technology. ICO system is planed to go in service in August 2000. the system is designed to offer digital voice, data, facsimile and short targeted messaging services to its subscribers. ICO’s primary target customers are users from the exiting terrestrial cellular system who expect to travel to location in coverage is unavailable or inadequate.  Ico system is design to use a constellation of 10 MEO satellites in Intermediate circular orbit , at an altitude of 10,355km above the earth surface.  These satellite are expected life of 12years and arranged in two planes with five in each plane.  The weight of these satellites is less than 2000kg.  The expected life of these satellite is 12year.  The frequencies used in ico is 2170-2220Mhz for uplink and 1980- 2010Mhz for downlink.
21. Comparision between Globalstar,Iridium&ICO Feature Global star Iridium ICO No of satellite 48+8 66+6 10+2 System type LEO LEO MEO No of planes 8 6 2 Orbit altitude 1414km 783km 10,353km Inclination 52degree 86.4degree 45degree Gateway 102-210 12 12 Lifetime 7.5yrs 5-8yrs 15yrs Mass 450kg 700kg 1925kg Service lunched 1999 1998 2000 Output power 1000watt 1400watt 2500watt Modulation QPSK QPSK QPSK Data throughput 7.2kbps 2.4kbps 2.4kbps Access method CDMA FDMA/TDMA FDMA/TDMA
22. CONCLUSION By going through the above slides we came to know that satellite is mostly responsible for telecommunication transmission and reception of television signals and whether forecasting which is very important in our daily life. Satellites are having some disadvantages till now. If they are improved to an extent that the delay will be minimized then I will be a golden achievement of science in our life.

It drifts back and left. I was sold on the claim that its internal controls are so sophisticated that there is no need for trims. I can't keep it in the air for longer that a few seconds. I am a complete novice with flying RC copters, and that's why wanted something that is inherently stable and well protected. Well protected, it is, even though after 3 flights one of the legs broke off. I glued it back and so far it holds. Mind you, I crash it constantly as a result of its instability and my inexperience. So, that's a pretty minimal damage, considering that. If it was a copter with unprotected blades, it would have been destroyed on the first flight. Note, that I can fly it only indoors in a fairly small room.I don't find the noise being bad at all - nowhere close to what I consider loud noises, like an air dryer or a mixer.But the re-charging time is too long, considering that the battery is not removable. The result: about 6 min of play time (actually, frustration for me) and 1 hour of waiting for recharging. I wish the battery was swap-able.Overall, it is a pretty ingenious little toy and I hope that I can learn to overcame its instability before I give up and return it in frustration. The whole point of buying it was to learn to fly indoors before I graduate to a bigger (and more expensive) copter.Read more11 comment|
Was this review helpful to you?YesNoReport abuse3.0 out of 5 stars5 star to amazon but 3 star to product.ByMaxon November 20, 2014Format: Toy|Verified Purchase5 star to amazon but 3 star to product. for this price I would expect to Helix to go up strait but it does not, its like not being calibrated right, the second that Helix want to go up it will start to go to the sides as well no matter how hard you try to control it for holding its position strait up, it will continue moving to the sides (right or left). I will return the product, I bought this for my nephew, I am 36 years old and I having a hard time controlling this toy, I don't want to give frustration to my 10 years old nephew.I forgot to mention the noise, when you start flying this toy you will hear the same noise when a garbage truck in on R gear mode, I personally did not like the noise and it is loud.Read more11 comment|
Was this review helpful to you?YesNoReport abuse2.0 out of 5 stars$35-$40 Toy for adult kids that don't want to break the bank with a Phantom.ByDIGITALidon January 19, 2015Format: Toy|Verified PurchaseThe Good: Durable little guy. The charging option directly on the remote is cool.The Bad: Non-replaceable battery seems to take forever to charge. It lasts just a paltry few minutes. Like all the others have discovered this does NOT calibrate well just stationary this thing is all over the place. Its like trying to teach a camel how to ice skate. Mine does not rotate to the left well AND when I try to it drops a few feet. Like the power reduces and doesn't compensate correctly for rotation. Its slow to respond to controls. Except that stunt button. That one seems to work immediately especially if you hit it by accident LOL.The Ugly: The look on your face when you realize all those fancy toggles and options on the control are fake. 8 batteries required! No antenna?The Summary: This is a $35 toy for adult kids with a ton of patience. Not for kids they will toss it. Its a lot smaller than it looks in the pictures.Read more11 comment|
Was this review helpful to you?YesNoReport abuse2.0 out of 5 starsFar too expensive for what it is...ByDoc1on December 1, 2014Format: ToyMy wife got me one of these for Xmas 2013, so I have had almost a year to play with this item and give you my take.Pros:1. It's plug-and-play, less to do than other mini-quads.2. It is VERY tough.3. The foam surrounding the ducts saves the quad and your big screen when running into things in a small space.4. The pre-canned stunts work well.Cons:1. Not priced realistically. Last year they were $80. They are now $60. This is really a $25-$35 toy.2. Because of the design, it simply is not an outside quad.3. Non-removable, non-replaceable battery.4. Battery definitely has a run life... 2-3 flights a day and the battery will significantly degrade after 6mo.5. High Sensitivity setting is the only real way to fly it. Low is horrible.At the end of the day this is an expensive, very tough toy for indoor use only. The Syma X1 is a far better entry-level quad and is only $30-$35. If you must have a surround around your blades, there are other quads cheaper that will fly outside much better. I think "Air Hogs" are more about marketing. There is a lot of fun to be had with the X4, but it is severely limited and I'd be surprised if you get a year out of the battery. For $60, shop around.Read more11 comment|
Was this review helpful to you?YesNoReport abuse5.0 out of 5 starssuperd quadcopterByDonald J. Kovacs Jr.on March 22, 2015Format: Toy|Verified PurchaseGreat Quadcopter cant beat for the price. As previous reviews highly recommended to use the expert setting on the controller to give better precise control and quicker reaction movement control during flight. Though states its a indoor use it can be used outside if wind speed is 0-3 mph max. Indoor use is best only if you have a decent wide open space free of obstacles. Flight time is expected for its internal battery capacity so 8-10 mins during initial learning directional movements is expected. Best to charge with the usb cord provided to all optimal battery charge in remote. To start lift off you will want to start with half pwr throtle max untill you get more acustomed to manuvering your quadcopter. The inclosed ducts provide great durability and performance and though the body is steardy and durable it is best not to allow uncontrolled flying.Update: Since purchasing the helix i decided to do a wiring modification and upgrade power supply. Added JST connector for easy battery swap and a LaTrax Li-po 3.7v 650mah battery giving it low profile a weight distribution to not interupt gyro balance on flight. Unfortunitely going any higher in mah can give you even longer flight time and increased power but unless more modifications on housing it to the helix weight and flight aerodynamics will be greatly effected. I have attached before and after of modifications to show internal components, accessing the battery bay and mother board must be handled with caution. Upgrading the battery has provided increase in flight time, flight power and slight added weight from bigger battery gives more stability indoors and even outdoors of course with low mph winds.Read more
