Default Servo twitch makes truck go crazy...news at 10!

I fried my stock axial servo, and in my quest to get my rig up and running again, I picked up a tower pro mg995. I run a CC BEC set to 6v, it powers my rx ad well since my ESC doesn't have a BEC. If I apply resistance against the servo horn, the truck will shoot forward or backward a few inches. I have tried lowering the voltage in the BEC but I hasn't seemed to help. Any ideas on what the problem might be? I have read mixed reviews about this servo, but even the negative ones didn't site this type of issue.

Mine does the same thing. I am gonna try to rewire the way the cc bec is hooked up. red/black out of cc bec directly to the red/black on servo, the the white signal wire from servo into the rx and power the rx with the esc BEC through red wire if that makes any sense.

Touche! I've never even heard of that model. Either way, you should still pull the red wire. The CC BEC wiring diagram states that only Phoenix ESCs need to disregard:

I went thru that with epee on a different thread, with the red wire removed the esc has no power. Castles instruction say to disregard if using a Phoenix esc, my esc is very similar.

The new servo is digital and the old stocker was analog, I'm still using the stock am radio and that may be the issue.
