Hi,
I did a model.ini with the following features
CH1     AIL     Dual Rate on AIL DR
CH2     ELE     Dual Rate on ELE DR
CH3     THR     throttle curve on MIX 0=1-1, 1=heavy model, 2=light model
CH4     RUD     Dual Rate on RUD DR
CH5     TRIM_L+ invert (virt7, virt8, trim7)
CH6     TRIM_R+ flip (virt5, virt6, trim6) push button and move cyclic to direction
CH9     FMOD    Flightmode -100, 0, 100 (powerlevel ?, headless mode)
        TRIM_R- Gyro callibration (only if THR=0)
        GEAR    Emergency throttle hold
The original tx features two different power rates which I wasn't able to figure out how they work. They don't seem to be on channels 7, 8 and 11. (10 is known to be return to home which is not yet implemented)
