Well this motor i bought it and i was a little unsure but it performs really really well it does about 30 with a 2s Gearing 12p 51s a little low i wanna get a 17pp but this motor after a full hard run on the motor about 145f but your going to have to drive it really hard like thick grass full throttle all the time in about a 7 pound truggy but just bashing about 120-125... you should get it! i would buy it again!
