Status: offline 		As im flying my cx it turns right, and it makes like a glitching sound as its doing it. It is out of control at that point. It only seems to happen when i give it like 75% throttle and up. I replaced both motors thinking i had a bad one but i guess its not the motor. Anyone have this problem or have any ideas?

Status: offline 		Not sure what you mean by a 'glitching' sound exactly. Maybe a bad bearing??

Can you take a short video (with sound) of it happening, and post it for us to take a look at?

Status: offline 		I dont know about you guys but that sounds like a bad motor.Or 1 getting ready to seize up. How long have you had the CX and about how many hours on the motors??

Status: offline 		Ok NM that last guess cuz you said you replaced em. Have you checked your main gears for missing teeth??? Or maybe is your gear mesh a little too tight??

Status: offline 		Forgot to mention this: Remove 1 motor plug from the 4 in 1, then run it full throttle while holding it down. Do this for each motor until you find the one that has the problem. Then, inspect every part that turns that rotor.

This sounds very much to me like a shaft slipping. Once you find which rotor is causing it, hold the corresponding gear with one hand, and gently but firmly try to turn the rotor with your other hand. See if you can make it slip. If you can, something's not tightened down somewhere. Check everything...

Status: offline 		Ok it is the lower blade that is slipping, i tighten the set screws for the lower blade but i guess it isnt tight enough, i didnt install it correctly

Status: offline 		Is it the blade that spinning or is it maybe the gear spinning on the shaft?? I dont have a CX here to consult but isnt the upper gear the one that controls the lower rotors??? If it is (guessing again) I also think that gear is a pressed fit onto the shaft. Theres no way to tighten this 1. You need to replace the shaft and gear. Like a 10 dollar fix. Like I saidd Im just guessing here cuz I no longer have my CX. Anyone else wanna double check what im talking about plz?

Status: offline 		its fixed!! what happened was i didnt have the lower blade on the shaft correctly... where the little screw goes in, i didnt have it in the hole on the shaft, stupid mistake but having all of you guys input helped me figure this out... i dont fly the cx much because i have a cp but i moved by the intercoastal and its too windy over here to just go outside, so now im flying the cx and the simulator to keep up. So thanks for all of your help.
