I hope to find out tomorrow (or the weekend at latest) whether or not the issue has been resolved by moving the esc to motor wires over to the other side of the heli frame, attached to the skid support on the right side.

I am confident this will resolve the issue, since the glitching occurred this past weekend, and I noticed that once I mount the canopy it pushes the esc motor wires up along the left side front skid support, practically touching the receiver antenna.

A new TX/RX system is out of the question, as this was a heli I built with my dime for my brother-in-law and he hasn't yet paid me for the heli ... let alone even tried to fly it yet. He had a FP heli and once I upgraded to a CP, then to a T-Rex, I had to build one for him as well. Besides, I have the exact same radio system in my Rex and have no glicth issues what-so-ever, only difference is mine has a CF frame.
