I put it in my B4.1 in place of a Novak SS Pro 13.5. Geared the same 31/75 and the Fantom seems a couple mph faster and def more punch, 115 degrees after 5 min. So I geared up to 31/69 and it is REALLY fast. Tons of punch and it has huge top end. Wheelies if I punch it at anything less than 1/8th throttle on the straight. Came off at 135 after 5 min. No added timing on the motor and esc is a GTB2. Is it fair to run a mod rotor in super stock non ROAR?
Depends on what your local tracks rules are about motors. You could ask your race director and if it's ok I wouldn't see a problem with it. We remedy this at my local track by just running 'open' classes.
