I think I have a bad Servo for the front T-Lock..
It will always lock the T-Lock, but when I go to unlock it, the servo will not do anything, I have to put pressure with my thumb on the only moving part on the servo, then it will respond like normal.
The problem is intermittent.
Im going to give Traxxas a call monday and see what they say. Im finally having my first issue with my Summit.
P.S.- today is day 7 with my Summit.
