4.0 motor review
 

Recently I got a bunch of stuff look here http://photos.yahoo.com/danktrees1212
and in the 4th picture, there are 2 4.0 motors. I tested them recently, they're pretty miserable on torque. They have absolutely no torque. it took me like 5 seconds to reach full speed. they're really fast tho. but i put them in my booster bit and they fly since the boost gives it the initial torque that it lacks. and just so you know, i post the link for all 10 photos to show off lol :P

..how much were they?? where did u get them??..i would like 2 get 1 also...thanx man

His dad got them from another country but if you look on Ebay you can find them. But the 3.8 perfecton is a much faster motor.

yea they're really slow acceleration. no torque at all lol. but after 5 feet or so you start to fly.
