Locking the revo in 2nd gear to use motor braking/reverse

[BrianG]

If you're getting binding, there could be two causes that I can think of:

1) When you do the 2nd gear lock mod, the 4mm screws you use to lock the clutch may be causing an issue. I noticed that when I threaded those 4mm screws in, the end of the screw sorta "pushed" some plastic out and may get in contact with the output gear. An exacto blade is easily used to trim this.

2) When doing with the larger pin mod, you could be overtightening them. It's hard to explain what's going on, but basically they are too tight causing the gear to flex. Try backing off a 1/4 of a turn.
