RE: Losi XXX-NT engines, difference?
i have found that a SG shaft motor requires a flywheel with a larger collet hole, i would say stay with a standard crank and go with anything from a .12spd to a cv-r.18 ...... i run a cv-r .18 in my ad2tq and its way fassstttttt ... very hard to keep the front end on the ground, it fly's the front on command!!!! my tz .12 turns over 10k more rpm's so its a way faster top end motor .... it rips the tires from the wheels tuning out the top end!!
