My DX7 setup for the Falcon is as follows : ( if something is not listed I did not change the defaults )

My Falcon is capable of much more negative pitch than positive so the low pitch setting will never go to 0% . 36% is matching the most positive with the same negative . Not sure if all are this way or not ....

Main setup
[Trainer] INH
[Thro recovery] INH
[input select] Aux2 = INH Gear =Gyro
[Swash Type] 1 Servo Norm

[Prog.MIX1] =INH

[Reversing SW]
Ch1 Thro = norm
Ch2 AILE = norm
Ch3 ELEV =Rev
Ch4 RUDD =norm
Ch5 GEAR =Rev
Ch6 PIT. = Rev
Ch7 AUX2 =norm

[Sub Trim] all "0"

[Travel ADJUST] (this may change for you depending on servos used etc)
GEAR = +/- 100%
AUX2 = +/- 100%
PIT = H 80% L150%
[Throttle HOLD] hold pos. -5.0% SW: RUDD D/R

[Throttle Curve]
Norm = 0% 25% 50% 75% 100%
ST-1 = 50% 50% 65% 75% 100%
ST-2 = 100% 87% 75% 87% 100%

[Pitch Curve]
Norm = 50% 62% 75% 87% 100% ( I did this as I prefer only 1/2 deg neg pitch when landing in norm . Basically acts as a fixed pitch heli from half throttle down )
ST-1 =50% 62% 75% 87% 100% (this% is where my heli does not change pitch between the norm/3D setting.This may be different on your heli/motor combo etc)
ST-2 = 36% 56% 75% 87% 100%
