hmm that 1521 will generate at least as much HP as that gas motor can. Is he doing something different with the transmission? After looking at the gearing and what not you would really need at least 8s to run 40+ properly w/o heat issues iMO (6s maybe 32-35). That is with a 19t pinion on the 1y or change up accordingly if using a different motor. there is always a 1527 or the 21xx's if you are really crazy :)

Hmm id bet a dual 1515 1y config on 5s x2 (dual mmm's) would do the trick too.. seems like there is plenty of room :)

you can't compare motors based on bhp ! i meen a .21 nitro engine can put out about 3bhp but they don't have the tq of an scooter 3bhp engine !

i whan't to use an outrunner becasue thet are very cheap (65$ for a .200 size outrunner ) Compared to a lennher or neu for about 500-900$ :)
