I recently bought a Chameleon Pro 19T for my nephew's Evader ST. I have an Orion Formula SV Pro BB 13x3 in my
Evader BX Pro buggy, and with identical packs fresh off the charger, the Chameleon Pro hung within 2 feet in a
100 foot drag race. Says something about both motors I suppose

.
EDIT: I bought the Chameleon Pro because the guys at the LHS race with them, and love the motor.
