Horizon Turbo Timber Evo - Throttle problem

[Bill Brinnier]

My Turbo Timber Evo with as DX6e Spektrum radio has a throttle that is not responding to transmitter inputs. All the other control surfaces are working properly. The throttle just sits there beeping. I’ve tried all the trouble shooting tips but to no avail. Help!

Did you run the throttle trim all the way down? Did you calibrate the ESC?
