1/4 scale Cobra
Hopefully here are pictures. All hardware is scratch made. Air scoops and bow light were from solid pieces of brass cut out and hand filed,shaped polished and chrome plated. Steering wheel turned on lathe from a 4" bar stock aluminum, polished and painted. Chris Craft logo cut out on scroll saw from brass sheet then chrome plated. Turtle deck was formed with styrofoam
then covered with three layers of epoxy reson and 4 oz. cloth. Wind shield was formed from plastic storm door material heated to 200 degrees for 5 minutes and placed in male /female wood form. Door edge guard was used for frame. Boat is 54" long and
expected to weigh 27 to 30 lbs.
Gauges are currently resized Dumas decal. Would like to get pictures of the real ones so I can make them look better. Also
need idea on size and profile of gauge trim rings. The last thing is to get pictures of Crusader Marine logo to go on dummy
engine valve covers. I hope you guys like what Iv'e done so far . Thank you ,Gary

I still have a little tweeking to do on the hatch cover and seats.I also have some one working on the flag for the front flag staff. When I get it , I have an idea how to make the miniature grommets for the flag from 3/32 brass tubing. I will post it when I find out how it works out. See you later , Gary

Grayman, The gas engine has a tuned quiet pipe which extends all the way to the transom where it exits through the exhaust port. I will also need to do the plumbing for the water pump for cooling. I made the rudder shaft from tubing
for the pickup. The motor has an electric starter and clutch so will draw water when idling. Thank you, Gary

Does anyone have any information about boat trailers used for the Chrsi Craft Cobra? I would to build one for my boat but need pictures or drawings to do so.
Thank you , Gary
|Feb 28, 2011, 05:32 PM
Was there any such thing as a Chris Craft trailer? I've seen old pix, CC's on the back of trucks, in simple cradles, etc... but no modern trailers like we use today.
Unless there was such a thing, you won't go wrong just building a trailer along the lines of any modern unit. And in 1/4 scale, you could probably use real mini-trailer tires, or wheels from a lawn-garden cart!

Chris craft Trailers
Patmat. I have a 1953 Ad for Chris Craft trailers. It shows four models. The
largest one had a capacity for 2300#. It has a rectangeler frame with 6 cross
bars and tandom wheels. It is hard to determine the size of the trailer and if
it was used for the Cobra, the end of it would have to be short of the transom
to clear the prop shaft. It also does not show any rollers or pads for the boat
to rest on. They may have been options based on the hull being used.
It also says that the trailers were blue and had yellow fenders Trailers also had shocks. Since this ad is from 1953, it may not show the one for the Cobra.

Chris Craft trailer
Millertime. Thanks for the reply. It appears that the boats were hauled in
their cradles on the trailers. I think I can bulid a mockup of one first before
making the real one. The suspension was unique for the time. Independent
and with shocks. It looks like they may have been swing arms with coil springs and shocks. it looks like it will be an interesting project. Thank you. Gary
|Mar 02, 2011, 05:31 AM
Hey, here's a picture that looks just like yours-- only upside down!
That's some neat history. CC also offered small boat kits, and some of those trailers look like they would have supported that market.
So when did the modern boat trailer become the norm?

I,m currently having the seats redone. I had to make some changes to the seat back so the old one didn't fit right. While I was at the upholerers a customer came and mentioned that I might consider them to make a cover for the boat. I
decided to do that as well. It will be a week or so before I 'll pick it up. Will post more when ready. Thank you, Gary

Millertime, I used the Ad that you sent me to build it. I know I don't have the right suspension system but hope to change it later.
It appears tht some of the early trailers used a cradle on the bigger boats.
I'm trying to find a good picture of the fender so I can see what the logo is. I can tell that the large letters are Chris Craft but can't tell what the small ones are. By looking at the rest of the ad, it could be Chris-Craft Corporation, Algonac. Mich. or Chris-Craft Trailer Division. I don't know for sure. I will try to go to the Chris- Craft Club sight to find out. I'll post when I find out Thank you , Gary

Toledo Expo
Sorry guys, I had thought about having my Chris-Craft Cobra at the Toledo Expo but, the two parts that I outsorced did not get done.
I had been working on the trailer while the boat was at the upholstery
shop. Two days before the show they had not started on my job. Since I didn't
give a hard deadline , I guess it was my error also. I also am having someone working on the burgee which as well isn't done. I guess I will have to wait til next year for Toledo.
Currently I am not informed of any other shows within reansonable driving distance for this year. I'll keep you posted. Thank you ,Gary

Hi guys , I would like to thank Frank G from MACK Products. He gave me
a web address for ModelFlags.com from the UK.
They had Cris Craft flags and burgees for my Cobra. They come in several
sizes so I ordered a 125 MM and a 150 MM. approx. (5'' and 6'' )in length. HopefullyIi will have them in a couple of weeks. Thank you Gary

Power sorce for 1/4 scale Cobra
Hi guys, While attending the Toledo Expo I was able to talk to a couple. of fellow boaters. I was showing them pictures of my Cobra discussed what power I had planned to use. Currently I have a 700 HO motor with a Traxxis esc. on two 7.4 v. 5000 mah nimh batteries. I was told that this system will not be large enough to power my Cobra. The boat will weigh about 28 to 30 lbs. running. I might burn out the esc. or motor under such load. I would like to get as much information as I can before making a change. The system I have may be better suited to convert my 40" Dumas hull to electric. Any feedback will be appreciated.
Thank you ,Gary

From what I can see with my HO trains these motors turn too slow for a boat.
I thought the electric motor in the Cobra was just for emergencies. Go back to MACK to get the right sized motor for this boat but tell them the motor is just for emergency retrieval and not for full performance.. Pete

Cobra got wet
Hi guys, I was able to launch the Cobra, but had less than steller performance.
The boat made one circle and stopped. When I got to it smoke was coming out of area where the motor is . I assume the motor burned out. I didn't get more than 30 seconds of run time. The rudder was still working so I believe the esc
is all right. The batteries, ecs and motor did not feel hot. I tried to get motor to
turn with wires connected directly to the battery but nothing happened.so I believe the motor is the problem. I didn't have my spare motor with me ,so could
not make the switch.
All I was able to accomlish was some still pictures. Thank you, Gary

|May 10, 2011, 04:33 AM
Did you use the motor in your picture titled electric option, wow, thats way too small. did you put on the same prop as the gas option.
Are you hoping interghange between style's of power ?
|May 10, 2011, 10:20 AM
Absolutely beautiful, fantastic job. This size boat needs some horse power. I would use 2 speed 900's geared together, running on 12 volts, direct drive. That would give you almost 1/4 hp at 13,000 rpm.
In the picture the 900s are the power ones 3,000 rpm@ 12 volts they are pushing 55mm 5 blade 1 inch pitch props.

1/4 scale Cobra power
Hi guys, The power I have is a 700HO motor , a t-max esc and two 7 cell nimh
batteries running on 16.8 volts. The prop is a 6717/ 3 . It is the size that I run
on my gas race boats.
I put spare motor in and everything checks out ok. Maybe I at least should go
to smaller prop. I have also been advised to go to 900 size motor.
The final running weight is 33 lbs. Since electric power is new to me , I appreciate any imput. Thank you, Gary
|May 11, 2011, 10:03 AM
Her's a picture of the 900 motor with the 750 (800), 550, and 540 size.
987 motor:
7 pole
6mm (1/4 in) shaft.
51.9mm dia.
69mm length
the 700 is about 1/2 the horse power of the 900.
at 35 lb you need more horse power.

Power for Cobra
FrankG from MACK mentioned the use of a 900 motor but, I don't see it on his web sight unless one of his motors listed as another number. He said I should use a 900 motor 780 kv to spin the prop I had about 9000 rpms to get approx. scale speed.What I don't know is will I have to use a totally different complete
system, ( batteries,esc etc.) I will try to call him to find out. Thank you, Gary

|May 12, 2011, 02:44 AM
The electric will only be for pottering around if you use the can motors, and the prop is way too big unless you either gear down or find a low rpm motor.
The gas motor is equivelant to about 4HP, 250 watts is around 1/3 of a HP.
Getting this to move on electric is going to be expensive.

Nick 75AU, I built the boat intending to power it with a gas engine. After
talking to a friend, he mentioned using an electric motor because it would be cleaner, quieter, no gas odors and I could have a reverse. So that is why I put an electric motor in it.
I also didn't fuse the system so the motor bacame the fuse. I have changed a few things and am waiting for the next run Thank you ,Gary
|May 24, 2011, 04:29 PM
Gary, fantastic looking boat you have made!
Well, like Nick mentioned, you would need quite a different set-up to get it truly
moving. To get it planing properly, I guess you would need at least 2,5-3KW
power for it minimum. I played with quite similar sized project myself some years back, 67" length Riva. I used 2 pces 10-pole watercooled outrunner Flyware T-REX 700kv motors, 2 x 10series LiPo batteries 6000mAh.
Each was end of the day pushed 100amps at apprx 34 volts, 3.4KW,(total apprx 6.8KW/9,3hp) water rpm apprx 16.700rpm with 55mm prop. Ok, for scale like moving that was
a bit overkill, but anyway gives an idea where the window is moving.
Best regards,

1/4 scale Cobra
Hi guys, I finally got my boat back in the water but was not very impressed. I tried by using a 900 motor and x455/3 prop. I did not burn out anything but it went about as fast as a rubber duck in a wind storm.
I will just have to try plan A whitch is the Zenoah. I have been working on it to get the electric starter to work properly. I built a test stand to try it out. At first it seemed to work great but the gear flywheel spun off stripping the threads on the hub. After fixing with parts from the other unit.
I tried to start engine again and the motor did not have enough power to turn engine over. I put second assembly on and it worked ok until after about 5 minutes running the engine, I shut it down to restart. The whole end cap of the electric motor had come off. After putting it back on, this motor didn't have the power to turn over engine.I tried about 4 times for 3 to 4 seconds to start engine and the wires to the electric motor came off by melting the solder. Also the oneway bearing failed. The new version of E starter does not use the the oneway bearing and has a bigger motor ( 580). I put it on the engine and when I
tried to start it , the adaptor broke. I emailed manufacturer and reply was that a billot adaptor is available that would correct that problem. I am waiting for parts
before I can resume testing. I'll let you know what happens. Gary

Hi guys, I would like to show you what I am working on. A 1/4 scale 1955 Chevy to pull the the Cobra. I traded a boat for a 1/4 scale Nascar chassis and have
obtained a 1/4 1955 Chevy fiberglass body. I bought a set of wheels and
tires and put whitewalls on them. I'm still setting up the body mounts in order to attach it to the chassis. I obtained a razer scooter that I think I can use the motor and battery pack for power. what do you think ? Thank you ,Gary

ESC for 24 v motot
Hi guys, I posted this question on th car forum, haven't got answer yet. Band1 replied about the chassis, but not the esc. I am
looking for an ESC that will work with the 24 v. motor I am putting in my 1/4
55 Chevy. Most of the ones I have found that they are either too low voltage or the high voltage ones are for brushless motors. The only place that looks promasing is a company that supplies components for robots. Any assitence would be appreciated. Thank you, Gary
|Dec 23, 2011, 02:07 PM
The robot boys do a lot of higher voltage stuff, may have something.
Did you try it on 12v? Maybe that's enough!
|Dec 23, 2011, 02:32 PM
I second. Look at the robot market. I have ordered from the Robot Market place and would recommend them. I currently run a robot ESC in my tug and will be purchasing from them again.
|Dec 23, 2011, 08:17 PM
I also have used Robot Market place, Ive got the IFI Speed controllers at 120 amp. They can drive 4 700 motors in parallel. You could get away with a much smaller 60 amp 883 unit from them. You do need the PWM cable, and don't run more than 6 volts, 4.8 ideal into the receiver (the PWM cable will fail at anything over)

esc for 55 Chevy
patmat I was able to get the motor to work using a traxxas EVX 2 esc and 16.8 v nimh batteries but, I was told it could harm the motor running on low voltage. The motor and battery pack came from a Razor scooter. The speed control for it was broken at the handle. I noticed that two wires coming out of the speed control. One went ot the handle control and the other goes to the brake lever. My guess is that the wire going to the brake lever is simply an on /off switch
so you can't have power to the motor when the brake is on. I am assuming that if I jumper that wire, I may be able to hook up the other one with an esc.
In the pictures these wires plug into the white recepticles. Since the wires are small, I think the current to handle control is reduced and may allow me to use a lesser voltage esc. I appreciate any help any one give . Thank you ,Gary
|Dec 24, 2011, 11:17 AM
No worry, you won't hurt the motor...that was told to you by someone who doesn't understand dc motors.
Only if you have a situation which forces a given load , and near the motor's limit, will reducing volts (and increasing current) cause harm.
|Dec 24, 2011, 01:02 PM
Did you look into
Vantec RDFR Series Controllers - An Overview
|Dec 24, 2011, 02:14 PM
Trash all of that original control, it has no speed regulation at all.
As patmat wrote low voltage wont harm the motor, it just runs slower, if you halve the voltage you only get 1/4 the power, as you probably wont go racing with the trailer on the back the motor will most likely have enough grunt to power the car. My only concern with the the traxxas ESC is that they are not designed for a large multi pole motor like the scooter motor.

Question. Swordfisk ESC.
Hi Guys, I tried the Cobra on a new setup. Its a Castle 2028 motor and a
Swordfish 240 Amp ESC and 8s lipo batteries. When I tried it, it would run about 3 seconds and shut down . I pulled the throttle to 0 and it would go again for about the same time and shut down again. It did it everytime I tried regardless of throttle of setting. There was no heating of wires , control or motor. Does anyone have any experience with this ESC? Thanks, Gary
|Jun 16, 2012, 08:30 PM
I think the ESC is shutting down on high current, my honest opinion is you are running the motor on too many cells.
The motor is 780 Kv (correct me if I'm wrong) 8 cell is 30 volt nominal so the motor is trying to spin the prop at 23 500 RPM, this is much higher than even gas boats with surface drive props and a sub surface prop puts a higher load on the system
I can't recall if you mentioned the prop size, but guessing a 70 mm prop, for sub surface less than 10 000 rpm is going to be much closer to the mark.
I tried my Riva Corsero on 6 cell 500 Kv motor with a 48mm prop and it was way overpowered to the point I could not get it over 1/2 throttle.

G- you were also shutting down on part throttle... Did you see my note about the possible radio problem?

Swordfish ESC
Nick 75 AU The prop is a 955/3 . the motor did the same thing on the stand
with no load. I was told from Castle when I bought the motor that if I tried to run it on low voltage that it would pull high amps. I originally was going to run it on 4s
batteries. I think I think the problem has to do with the programing of the ESC. The only things I changed was the cutoff point from 12 to 24 v. and the type of start from standard to soft start.Everything else is at default settings, So I don't
know what to do until I can talk to someone who uses them or knows more about it. Thany you, Gary

Swordfish ESC
PatMat, I just read your Email about the auto shut off .I'll try other radio before changing the ESC. Thank you Gary

55 mm prop,
Power(watts) = Voltage X Amps
The amount of amps a motor will draw depends on the load, running a motor on lower voltage lowers the RPM and with the same load will reduce amps.
If you want to extract the same power out of a motor at lower voltage the amps have to increase to give an equivalent power and this is where Castle are coming from. In this case you would then have to fit a larger prop to increase the load.
I am 100 % positive the load, RPM is too high and the motor will pull silly amps and the boat will be too fast with the current 8 cell set-up.
Obviously its hard from the other-side of the world to diagnose a set-up problem with a radio or ESC, one issue could be the timing set into the ESC, the only advice I have is to set it to Castles specs for the motor.

I mentioned to Gary that it might be something with the radio. From a Swordfish description:
"Auto shut down when signal is lost or radio interference becomes severe for more than 3 seconds .After radio connection has been reestablished, moving the throttle to the lowest position can restart the motor."
This is exactly the behavior we saw yesterday.
Gary- Could also be something glitchy in the ESC's opinion of signal quality. The ESC knows nothing about the radio, it just looks to see if it's getting a believable PWM command stream from the Rx (which should be a non-stop string of pulses, one pulse every 20 ms, each pulse between about 1 and 2 ms long).
Another way to test would be with a simple "servo tester":
...which merely puts out a user-adjustable PWM stream.
Also make sure the lead from Rx to ESC isn't running next to any "noisy" wires.
The pic below shows the Cobra getting up on plane for about 1 second, before the shutoff!

Cobra launch
Hi guys. I haven't kept up with what I am doing with the Cobra. I now have my fourth attemp twith the drive train. I now have a 2028 Castle motor with a 240 amp
Swordfish ESC. and two 4s lipo batteries. My first attempt was at Heritage Park,
Canton ,Mi. The boat would start and stop about every 3 seconds. It would start after returning to off and up again.

Hi guys. I haven't kept up with what I am doing with the Cobra. I now have my fourth attempt with the drive train. I now have a 2028 Castle motor with a 240 amp Swordfish ESC. and two 4s lipo batteries with a 955/ 3 prop. My first attempt was at Heritage Park,Canton ,Mi. The boat would start and stop about every 3 seconds. It would start after returning to off and up again.
Patmat sent me info on the ESC. If it does not get a good signal, it will shut down and can be restarted in 3 seconds. I rerouted the wire fron the ESC away from the battery cables and everything seem to be allright.
I tried again at Heritage Park,Taylor,Mi. and things worked OK until the drive
shaft broke. It was a 1/4 " cable like I use for my gas race boats. It twisted off about 2" inside the stuffing tube.
You can see and hear what happened on youtube by going to "MSMBC Running at Heritage Park, Taylor Mi." Everything happens in the first minute
or so on the video. The main focus was not on my boat , but you can see it in the background and hear it on the second pass in the top of the screen.
I 'm not sure of the condition of the cable because it may have used in my race boat prior and may have been weakened. I will try again with the new cable.
I also was having handling problems at top speed and wonder if it the same as what the real Cobra had.I think I was going faster than scale speed. I let you know how things work on next run. Thank you, Gary

To Nick 75AU. Thanks for reply. At least I know its on the forum, just not where I thought it would be. It doesn't look too bad for a 33 lb. boat Thank you, Gary

mercedes C220
Hi, I'm looking at buying a 1995 mercedes C220. The mileage on it is 147,000. I want to pay $5500 for it if the inspection checks out. The dealer wants $8000. Are there any mercedes c2200 owners out there who can tell me how many more miles i can expect to get out of this car? It will only be driven on occasion, not a work vehicle.
I think you'll find many Mercedes owners who have more miles than that on their cars, and probably some of those have spent a lot of money on their cars getting them to those high mileages. One guy I know has an older Mercedes diesel with about 250,000 miles on it, but he had an engine put in it once, which probably cost several thousand dollars.
The mileage you're able to reach in this car before major repairs like that depends on how it was taken care of by the previous owner as well as how it was driven. In addition, the number of miles remaining in it before major repairs will depend on how you drive it. If you drive it only occasionally, you won't get as many miles out of it as you would if you drove it a lot, because cars deteriorate by time as well as mileage. However, its life in years will probably be longer if you don't drive it too much.

So what happens to foreclosures that don't sell?
So a house goes from no approved short sale, to foreclosure. The bank now owns it. Banks usually put these on the MLS yes? What happens to them if they don't sell? I'm most interested in houses that didn't sell because they are in poor repair but no one is going to want to sell the property for that low a price.
And where do sherrif auctions fit in? I know that banks often buy the house......because they own the loan....but I'm not sure why or when a house ends up at a sherrif's auction when they would have gotten it when it went into foreclosure?
Probably something about sold loans but not sure.
"And where do sherrif auctions fit in? I know that banks often buy the house......because they own the loan....but I'm not sure why or when a house ends up at a sherrif's auction when they would have gotten it when it went into foreclosure?
The "sherrif's auction" IS the foreclosure sale.
The property is auctioned according to the terms of the note.
Some places actually have the sheriff do the auction, other places that used 'deeds of trust' are auctioned by the trustee upon notice by the owner of the note that the terms have not been met.
The bank will bud at the foreclosure auction up to at least the value of the note (with any costs incurred possibly added).
If the bank wins the auction they now own the house, and it is commonly referred to as Real Estate Owned (REO).
The banks do not like the maintenance and other costs of ownership, but prefer not to lose money.
Mortgage insurance may have gone to the note owner if it is payable subsequent to the foreclosure.
If the bank does own the note, they may be willing to take the insurance and sell the house at more of a discount since part of the debt will have been paid.
Like many things in RE, how the banks handle things is local.
Oh. So the complete sequence is for sale, for sale short sale, sheriff's auction, foreclosure/bank owned?
So something that is for sale/possible short sale may not end up in foreclosure because it could be sold to a third party at the sheriff's auction?
Outside of sheriff sales for back real estate taxes or judgments, the sheriff's sale IS a foreclosure sale.
Foreclosure is what the note holder does when the terms of the note are not meant.
They way they accomplish the foreclosure is by a sheriff's sale or public auction, or even court action depending on the terms (and type) of note.
A short sale is when the note holder agrees to accept less than the value of the note (amount still owed) for releasing the note (declaring it paid off).
If the note holder would prefer this in some cases to a foreclosure, but not always.
It depends on how much of a loss the short sale is going to hit the note holder for.
Mortgage insurance may not pay the note holder when a short sale occurs, but is nearly always payable on a foreclosure.
The relative value of the propoerty, the note, any mortsage insurance, even the health of the note holder, can all come into play when the note holder must decide what path they wish to pursue.
In some cases their is also the possibility of a 'deficiency judgment' being recorded against the owner after the note holder sues them.
This can be mechanism to seize other assets the owner has that are not involved in the foreclosure.
Some state allow it, some do not.

I finally bought a keitai!
very cool. soooooo....where are the keitai pics?? LOL j/k
Congrats on the cell! I want to get rid of mine since the contract ran out, as it has become more of a nuisance and expense than handy.
:::Wondering if there is no going back once you have one?:::::::Danako
Thanks! I still barely know how to use the thing. It does take fairly good pictures though, so you might see a few soon.
And I do have a feeling that there's no going back. I didn't even want to get one, but they're just so necessary these days...
