Futaba T3PM and FrSky TFR4 loss of signal

[V6Jim]

Hi,

I have a Futaba T3PM Tx and a FrSky TFR4 Rx. Binds perfectly and the throttle works perfectly. Turn the steering and it works for a few seconds then the signal drops out and it goes to fail safe with the green light on steady and the red light flashing.

I have tried an alternative servo - same thing. I swapped the Tx and Rx for other ones (Not FASST) and it worked perfectly, so ESC is fine. Voltage output is a steady 5.7v.

Any ideas?
