My final DX7se settings to get swash operating correctly and to obtain factory pitch range are:

Swash Mix
AIL -65 (gives me 7° pitch L and R)
ELE +70 (gives me 7° pitch F and B)
PIT +30 (gives me 11° pitch pos and neg in ST1 and ST2)

Servo Reversing
ELE, RUD and PIT all Reversed (the rest Normal)

I am running a linear throttle curve in NORMAL mode and it seems as if I have more head speed than my CPP2 using the factory HP6DSM. I will need a tach to verify though. Factory calls for a more aggressive throttle curve than what I am running. I am a bit confused on this one.

Pitch curve in NORMAL is 35% 42.5% 50% 75% 100%

I have EXPO for AIL and ELE set at +20% and it is flying pretty well. I might turn this down just a touch.

I want to fly each again and evaluate the perceived head speed differences and flight characteristics.
