FXR ESC glitch
 
Hi RCTECH brethren,

I have an on going issue with my SCX10 that I'm desperate for help with. I'm running the following set up.
a

Dual Tekin 35T HD motors and dual FXR ESCs combo.
10amp CC BEC
HiTec HS-7955TG steering servo
Spektrum SR300 RX
Novak Glitch Buster
5200mah 3S / 30C discharge LiPo - one for each motor & ESC combo

I had about 10 minutes on glitch free crawling today and then it freaked out again. I tried disconnecting one motor and ESC then running the CC BEC from the battery into the RX but as soon as I plug any servo into the RX, the ESC locks up (all LEDs light up). I tried a Traxxas 2075 servo, which is considerably less power hungry than my HiTec servo and it won't even help matters. I get the same glitch / lock down. With no servo hooked up at all, the throttle works like a charm but as soon as a servo is plugged in, everything goes haywire and shuts down. I really need help sorting this out I've tried all sorts of combinations. I've tried removing the Novak Glitch Buster - no change, I've tried removing the servo signal wire and plugging it directly into the RX and sending the hot and ground wires to a Y harness that plugged directly into the BEC - no change, I tried dialing the CC BEC voltage up from the servo's max output of 6v to 7.4v - no change. There's got to be a way to run this rig as a dual motor / dual ESC crawler with a high torque servo on 3S/30C LiPos without incurring the dreaded glitch. PLEASE HELP!!!
