Elevator trim is moved on the D-Pad
The shift now needs to be pressed for trim.
This is normally the throttle trim.

The model starts in FM1. This is the throttle safety.
It can get out of safety in 2 ways:
- pressing the D-Pad down for 0.5 a second whilst throttle is on idle
- pressing D-Pad for 4 seconds (throttle position is NOT idle).

The latter is done for hand launching the plane where the radio is in 1 hand and the model in the other.
The countdown 3,2,1 can be heard before the throttle engages.
I have replaced timov3.wav with lnch.wav in /SOUNDS/en/SYSTEM/

Spoiler:
When FM1 is NOT active the D-Pad down gets repurposed for activating/deactivating the spoiler.
Both ailerons will go up to slow down the plane to minimize tip-stall.
This is FM2
Because FM2 has its own trim based on FM0
it is possible to change the amount of elevator compensation with trim

S1 is for flaps
If it has not been at 0 during throttle safety the whole function is disabled.
On this model having flaps is not crucial, but can be dangerous for the model if it is accidentally engaged.
I added logic so flaps need to be set to 0 during throttle cut.
5 seconds after throttle safety is turned off it will be enabled
