i just put a trex xl ccpm together and when i connect all the servo's they don't do what they are supposed to. it is like pitch become ail, ailerons become elev, and so on. they also glitch but they stop when i disconnect the motor leads so i'll get a ferrite ring. when i connect the rudder servo it just buzzes and when i try to run the motor it spool's up then surges. what the heck is going on, ALL HELP IS GREATLY APPRECIATED! here is a list of wht is in it:

ALIGN 430L (NEW)
CC35 (NEW)
TANIC 2220 3s1p (USED BUT I KNOW IT IS GOOD)
3 HITEC HS 56'S ON COLLECTIVE (USED)
HITEC HS 50 (USED) & EFLITE 75 (NEW TRIED IT SAME THING)
CSM 420E GYRO (NEW)
HITEC ELECTRON 6 (NEW)
FUTABA 7C (NEW) SWASH IS SET TO HR3 IN THE TRANSMITTER

Many things may be correct or wrong...

Make sure you have the correct channels in the receiver connected to the correct servos.

The previously mentioned channels are backward.

For clarity, a servo in the left is one that has the arms in the left side.

Read you T-Rex manual for the details, but in a Futaba (for a CCPM) it should be:

Channel 1 - Servo in the left front of the heli.
Channel 6 - Upper Servo in the right front of the heli.
Channel 2 - Lower Servo in the right front of the heli.
Channel 3 - ESC
Channel 4 - Tail servo
Channel 5 - Gyro Gain

Disconnect the thick (3) wires from the ESC to the motor.
Reverse channel 1,2 or 6 until you have all three servos moving the swash up with increasing throtle, and all move down with decreasing throtle.

Roger's Law: If it is worth doing it, it is worth exceeding it.

Set up your radio using a normal battery pack plugged into the receiver, initially. That way you don't have to worry about the ESC or its regulator contributing to your problem

Go to this thread:

http://www.runryder.com/helicopter/t217182p1/

and read my post, fourth one down, and very long, for a step-by-step procedure on setting up your CCPM controls. It will help you figure out which servo to plug in where, and once you do, how to get the directions correct for each servo and then for each function. It will also help you get the initial mechanical setup properly done.

Once you have your receiver and servos working correctly and properly moving you can then turn your attention to getting the ESC properly set up.

You can read about settings for the CC35 here:

http://www.runryder.com/helicopter/t208694p1/

again, fourth post down, very long, but will help you wade through the various settings.

Make sure you have NO binding of any servos -- a stalled servo will most likely cause the regulator in the ESC to go into thernmal shutdown, and make your receiver act weird, or quit working altogether (low voltage caused by the regulator not being able to source the required current).

That ESC thread should also show you a typical ferrite toroid installation, and gives you a source for them.

Just a question but do you have the cable that connects form your computer and your cc35. If you don't have it get one because have an incorrectly set up ESC can cause many headakes
