GY401 UPDATE:

If you have a stock Axe CP, don't try it. I could reference several threads on this board now, but the end result is that the GY401 requires features that are not available on the stock radio transmitter. Specifically, the statement is 'a spare channel with adjustable endpoints and/or switching capability' to adjust the gain 'pulse' signal from the radio to the aforementioned Rx channel. The pulse width is anywhere from 1.x-2ms, the variances are exacting, AND have to be timed with rudder control.

Sheesh. Soooo... needless to say I sent the GY401 back to Tower yesterday, and req. an exchange for a GY240 which has statically adjustable gain controls on-gyro.

And a note all the other flyers out there, IT IS WORTH THE PAIN TO PUT THE CANOPY ON EACH TIME you fly. I previously mentioned that it looked like my 3-in-1 board took a hit before, right? Well, I became curious the other day and went about removing the metal pot dial retaining lid and *poof* a corner of the pot frame flaked off... meaning the dial was not securely fastened to the slider contacts within the pot assembly... i.e. frame oscillation from the copter causes the gain dial to loose contact here and there. Either I need to order a new 3-1 Board or repair it myself.

MARKIND -- Could you confirm for me with your electronics expertise, that the Ohms on the center pot are in the range of 0-1.65k? IF indeed my numbers are correct, I may hit up the 'Crack and grab a replacement pot and see if I can swap out the busted one. Oh how I long for a lab grade de/soldiering workstation/vac unit like that I was trained on.

Clear skies and crashless flights to all. :-/
