But 2 out of 3 times I power the system on, the transmitter and receiver refuse to communicate. Note I have been turning on the radio first, waiting for the solid red light on the transmitter module, turning on the receiver, and waiting for the solid red on the receiver. 2 out of 3 times though, I will get a solid red light on both yet only the steering servo responds to radio input and even then it's glitchy and very slow. No throttle response. Or I will not get a solid red light on the receiver (keeps blinking for more than 60 seconds) and in that scenario, neither servo responds. So it's only working for me 1 out of 3 power ons. Note that it does seem to be better (works 3 out of 4 times) if I power the radio and receiver on when they are at least 4 ft apart. Go figure.

Note I know it's not my radio or my servos as I have tried the tx/rx module with another helios and it exhibits the same problem. And I have also used my radio/servos with the normal 75Mhz crystal module/receiver and they work great.

I sent an email to KO. Hopefully they respond back and exchange the parts for me.
