I saw some pix of a car that has two motors connected at once to the same gear. The 2nd motor was piggy backing the first one. I took a look at mines and realized it was almost a perfect fit if you take out the chasis thing that holds the motor down. I plan to do this but I'm not sure what kind of improvements I would see. Would two 2.4 motor result in an equivalent of 4.8 power??? I plan to first wire these two motors to the same battery but I am guessing the single battery won't be able to handle two motors at once. Thus I'm also planning to do the dual battery mod and hopefully that will give it enough juice to put both motors to full speed. What do you guys think?
