Default Futaba 3PM - Neutral Position Issue

My 3PM controller is acting up. Specifically, It doesn't hold the neutral position so the throttle brake servo jumps a bit. Specifically, either the brake is engaged when I let off the gas, or the throttle is stuck open 15%. I believe the problem is in the trigger (I have changed out servos and it didn't fix it). Does anyone have a fix for this?

My 3PM-TFS seems a little funky also. Nothing like 15% but the steering twitches sometimes and the trottle doesn't return to neutral perfectly.

If the problem is not any adjustments that can be made on the transmitter or a bad servo, most likely it is a faulty radio.

I have owned the 3PM for over a year and never had any problems. Same with many people I know. I recommend all of Futaba's radio gear.

True that. Im a Futaba only kinda guy. Ive never had a problem with my 3PM other than my battery tray, but that was my fault. Dont try to charge 8 cells on a charger designed for 7 cell max. it may also be a receiver issue. also try checking the connections from the servo arm to the brakes\throttle, they should move freely. I had a simjlar problem with my steering, turns out the steering bellcranks were binding a little bit. There may also be interference
