Allora ribadisco che so un po stanco e che non sono a casa, pero' riporto quanto dice il manuale a partire da pag.31, forse non ho capito benissimo il problema in ogni caso vedi se questo ti e' d'aiuto, leggi anche il manuale dove parla del reverse sul gas.

Adjustable travel limit
(
ATL): makes the channel 3 TRIM LEVER (THROTTLE TRIM) effective only at low throttle, disabling the trim
at high throttle. This prevents pushrod jamming due to idling trim changes. This function defaults to ON. If you are not using
channel 3 for throttle, you may want trim operation the same as on all other channels. To do so, set ATL to OFF.
If you need the ATL to be effective at the top of the stick instead of the bottom, reverse the THR-REV setting. Note that this
affects all models in the radio, not just the model you are currently editing. See servo REVERSE, p. 31.
