I have a hitec 5625MG, power of 131oz but only .14 sec speed, on MP777 and is enough, of course next time i'll find one with more speed. About my Hyper 8, i have the stock ones on and i'm very happy about the steering. I don't know the specs of the servos of course, but they must be around .12-.15 sec i think, as for torque, enough good
