Expo is set for all flightmodes.
If an expoSwitch is set (ratesExpo menu), then this value is increased by 25% and 50% by chosing switch-mid and switch-down positions.
Rates is set per flightmode or rateSwitch.
If a rateSwitch is set (ratesExpo menu), then you can alter the value for all switch positions. This value is then active for all flightmodes for those switchpositions.
If rates are set per FM, then the rate can be set for the active flightmode, and for each flightmode a seperate value.
If Rates are switched off, the current flightmode will have 100% rates.
The value in mm can now be edited on the Rates field.
It is only used to calibrate the unitless % values to a meaningful value in mm.
Flap2Elevator is used to mix in elevator based on flap or crow input.
Two seperate curves are used, one for Flaps based braking and one for Crow based braking. The correct curve is autoselected, based on Flap2Aileron setting in the Aileron menu being positive (Flaps based braking ) or negative Crow based braking).
When max Flaps applied, the maximum value of the Flap2Elevator mix can be set as a percentage of the maximum elevator deflection on a per flightmode base.
When an intermediate flap position is chosen, it shows both the percentage of the max value for that position, as well as the percentage of the maximum elevator deflection. It also shows the corresponding elevator deflection in mm's.
