I bought the fun piccolo and the kit of parts to get it flying, no problems except the piccoboard plus. The receiver part wouldn't work right. All that would happen was the servos would be very jittery and zip from side to side. I tried using a 4.8volt receiver pack to power it and the same thing happens, even with the transmitter off the same thing happens. The xtal I got with it is a Hitec single conversion and swapping it out with the one in the feather in my electric palne shows it's fine. Having the transmitter on or off makes absolutly no difference.

Well I sent it back and got another picco board, this one happens to be the pro version. This one didn't come with the plug and play connectors so it took some doing to get it set up and this one has the same problem.

I can substitute the reciever on the picco board for a regular receiver and the other half(the motor controllers and gyro) work fine.

I tried to simulate the problem with the feather receiver in my plane by removing the xtal and turning off the transmitter but could not duplicate it.

Any ideas? Is the hitec single conversion xtal the right one to use?
