First, mine arrived DOA but it was obvious that this is a toy and not really appropriate for proper training in radio control operation.  It's too small, doesn't have trim control and the sticks have none of the feel that an actual controller does.  I didn't get to test  its accuracy since it was defective but even if it was spot on, there are much better options out there - check out the Dynam 6ch controller - it is life size, has trim control, good feel on the sticks and works well with Clearview SE (free).  Don't even bother to download FSM, it is outdated, no longer supported and not all that good when it works.  The upgrade of Clearview is only $35 to get all the models and airfields or buy them one at a time to add to the freeware version.
