i'm concerned that the lx-1 won't be able to keep up geared 51/25, and it's no fun if you're the slow guy.

So let me get this straight...you're running a 2650kv on 6S and gearing it for ~120mph?

I'm quite surprised you haven't melted your motor several times over already. A ~6:1 FDR in a 1/8th buggy is going to put stupid amounts of load on the motor.
