Default Futaba 4PL Problem

Hi Guys, anyone run into this issue?,

My radio has the ch2 (throttle) at almost full (see pic, I'm not on the trigger), moving the trigger wont do anything. Any suggestions will be appreciated.

Did you check to see if the throttle subtrim got out of order somehow and it's so far over the throttle doesn't respond? Otherwise, it's possible the trigger's potentiometer has gone bad.

Thank You Mark, yes I did check trims to see if it did anything but did not help. Tried the advanced menu centering and it wont move, looking like I'll have to send it in for repair. Appreciate your response, Hope they don't take too long.

You have no mix attached to that channel?

Try to do a model reset.

Time for warranty....

Probably a loose wire or a bad potmeter.

Had the potentiometer go bad in my 3pl, so I made the switch to the 4pls. Now having issues with that one, so I just upgraded to the m12

Weird, channel 2 is steering, not throttle.

Unless you've been doing something "backwards", ch 1 is steering, 2 is throttle - remember the old phrase as to what gets plugged in were - "You have to be able to steer before you can go."

There is also a calibration function in the menu that is called 'Adjuster'. This lets you reset the centre point for each channel and is not effected by doing a factory reset.

For anyone else with this problem, you could try this setting before sending it in.
