Futaba T7C refuses to work with throttle trim. Plea for help :)

Have tried everything. Running a futaba T7C and while trying to get an eagle tree osd, RTH working discovered the throttle trim does not work. The trim button moves and there is an audible tone, but once the throttle is running the up and down trim buttons have no effect. Have a turnigy 60 amp brushless esc. It's important this is functional. Any help or recommendations is greatly appreciated.

If throttle trim switch is broken, you can use sub-trim to set trim position.

Throttle trim is rarely used during flight once it is set either gas or electric.

Thanks for the reply. Here's an update. Called Futaba and discovered the transmitter was programmed to reverse throttle. Switched to normal, then reversed the throttle channel. Trim is now working the way it should.
