There's nothing "wrong" with it, but there are reasons to do so:

- BL has more than enough power to start the Revo going from a standstill with enough force to easily pull wheelies, spin tires, etc. Maybe the use of a smallish BL motor would be less stressed with a 2-speed.

- The construction of the transmission includes a one-way bearing on the first gear. This allows the shaft to spin faster than the first gear does when second gear is engaged by the centrifugal clutch. A side effect is that you cannot use motor braking or reverse because of the one-way-bearing. You can use a brake servos and use the stock setup, but you still don't get reverse. No biggie if it's not important to you. Plus, the addition of the brake servo and parts simply adds weight and complexity.
