Here's my setup:

TREX 450XL CDE
ASTRO 803T 11t
CC35 w/ latest firmware fixed mode
100 97.5 95 97.5 100
+/-11 degrees
FUTABA 9C
Apogee 2170 15C
315 Woodies
(3) HS56 (1) hs50
401 Gyro

I have setup the endpoint on the radio according to the trex tuning.com. RPM holds throughout until i get to the max pitch and the rpms drop significantly. Should I drop the pitch to 9 or 10? when I try to fly a max pitch climb or 3D the rpm drop make me pull out of the manuever because the main rotor rpm decay. Any ideas?

Helicopters shouldn't fly, they are just so ugly they repel the ground.

Try a 13T pinion first but the ideal pitch setup is +-10* even for 3D you might need a stronger motor if that doesn't fix your problem.. How many degrees of swash travel do you have? Maybe it is binding at the extreme limits and bogging the motor.....

Tom..... No "D" flying....

I have +/-11*. I have 6* aileron and elevator. I don't have and binding issues that I know of, the servos don't buzz or anything. I'll try the 13t and see what that gets me. I just got the astroflight wattmeter, what types of reading should I be getting of the motor tests to see if I have a good setup?
