Status: offline 		I don't know how much mechanical setup you have done, but this website pretty much covers begginning to end and has programing for the T-Rex. http://www.helifreak.com/showthread.php?t=41692 You need to register to helifreak to watch the videos, but I think they are worth it.

I am using a DX7, AR6200, 3 JRDS285 servos for the cyclic, GY240, and a Futaba 9650 for the rudder for my T-Rex SEV2. Are you looking for throttle and pitch curves?

Status: offline 		yeah, im looking for throttle and pitch curves as well.
im, using pretty much the same servos you are except for the tail rotor, im using a jr hi speed digital for tail.

Status: offline 		In normal mode for Throttle I have:
0, 25, 50, 75, 100
Idle up Throttle curve:
100, 75, 50, 75, 100
You can make those numbers higher to keep the motor near max speed. This way it is a smooth transition between normal and idle up.

Normal Pitch curves:
The first number I made it so I got -3 degrees of pitch, INH, 50, 75, 100
Idle up Pitch curve:
0, 25, 50, 75, 100
This also has a smooth transition between normal and Idle up when you flip the switch in a hover. It doesn't jump up a few feet or have the rotors spin faster after flipping the switch.

Is there any other settings you need help with?

His settings may not work for you unless you heli is mechanicaly exact in servo travel and AFR travel when coping his pitch curves. It is better to use a pitch guage to establish the proper pitch in degrees. Not percentages in the computer program. You starting point will be center left stick and establish 0 degrees. Now move your stick all the way down or up or 3/4 and change the computer to the numbers that will take you to your pitch in the degrees that you want. You will need to adjust all 5 points in both normal and idleup. Sorry you can not copy anothers numbers when it comes to pitch adjustments.
