New buggy motor? (help choose)

[rootar]

i think a found my motor!!! NeuMotor 1512/3D/F/H it the heli version, has an internal fan, aluminum rear cap for the fan, and the body is also finned! all that and its on clearance from a heli store, it is awefully big but hey i can put 3mm spacers under the center diff and it has enough clearance everywhere else that i could go down to a 14 tooth pinion. (smallest i need to go is a 15 tooth)

what do yall think its 44mm around the finned area, in the rear it has a 50mm diameter ring as part of the cover over the rear fan, and its 71mm long, and it DEFINETLY will fit with 3mm spacers under the center diff OR if i grind the 50mm ring flat where it would touch the chassis


what do you guys think? should i order it or not?
