i got a cheap traxxas 2056 in my slash now and it works but i need/want more speed and torque. i went and bought a hitec hs-5645mg servo that was suppose to be faster and it had twice the torque but when i plugged it in it was slower than my traxxas servo. i went back to my lhs and tried the same servo and the same thing. i even went to another hitec that was suppose to be even more and just barely made an increase. i looked on hitecs site and i think it said that the digital servos could be programmed with another machine of some sort for more speed and crap like that. i just want to throw an upgrade in it and have it work better, not worse. maybe a different brand servo. anyone using aftermarket servo that they didnt have to do anything but install it?
