ive noticed when flying my plane it acts like its getting hit, i think maybe its the servos glitching . Its a tower trainer 40 with and os 40 and futaba t6xas radio and fp127 receiver . i also notice if the radio is off and the receiver is on and i pump the gas the servos go crazy but as soon as i switch the radio on it stops. My radio is PCM PPM selectable and i have it on PPM is that where it should be .
G'day Mate,
It's normal for PPM RX's to glitch the servos, when the TX is off, that's why you should turn your TX on first, then the RX, & RX off first, then TX.
Do a range check.
