the emaxx is a way heavier truck then this. no offense. the higher tern motors will give less torque. idk if it uses a reverse rotation motor. but if you really dont trust the power, you can use these. alot of people use them in clods and txt's and have no problem running them on higher voltage.

standard rotation

reverse rotation. you may need it for the front motor idk though

only thing you have to do is make a flat spot on the shaft for a pinion gear. these motor also run cooler the the titan motors
