I don't think you will be able to swap your Andy-Mark 9015 motors (am-0912) for the Bane-Bot motors because the output shaft dimensions are different. I have both sitting in front of me and can see that the output shafts are different. The Bane Bot output shaft is significantly shorter in length. Note that the Bane-Bot 550's I have in hand have been recently ordered (new for 2012). YMMV (your mileage may vary).

I am also seconding Kevin's suggestion above for the additional flywheel on your bottom wheels. We added this on Saturday to produce significantly more ball spin. Cavaet - not fully tested.
