Reverse
The help for this page of the Version 2 transmitter, as its latest update shows it. On the transmitter, Animation at the top of this help page plays a short film of the page in use.
On the transmitter: Model setupReverse
If a channel moves the wrong way, tick its box to reverse it.
Nothing changes until you press 'OK'.
'OK' keeps the changes and goes back to 'Model setup'.
Reversing comes last: after mixes, trims, subtrim and any re-routing on the 'Inputs' page.
So each box reverses the receiver output of that number, and the name beside the box is the channel routed there.
'Motor off value' ('Model setup', 'Options') is not reversed.
If you reverse the throttle, change that value to match.
