there is one with a 3.175mm shaft so i think that one will work. i am looking at this because i cannot seem to gear my rustler right to keep the temps down with the 7 cells with the 7700 so im shooting for a lower kv motor and i heard these motors are pretty reliable for the price.
Good motor, but very powerful, your cells will have trouble keeping up with this motor. I had one in a rustler and it would just blow the tires off the wheels. I would suggest a good 2 cell lipo, 6000mah or larger to run this motor properly. You will not be disappointed in power output, it is a beast. I even put it in an emaxx and it would wheely!!!
