Have Futaba 3PK with PK-FSM2.4G and R603FS rx
connect servo to ch1
connect esc to ch2

turn on TX, then turn on car

The fan on the esc then starts to fluctuate (faster then slower) and the LED on the RX flash red then green (repeating) when LED is flashing the esc fan also slows down.

Initially servo works fine, then servo action becomes irregular and LED flashes red/green again


apoligies it is really hard to explain.

Have tried with new servo (hobbyking) same issues.

Disconnect servo - issue stops

does anyone have any ideas what i am doing wrong?

cheers
