Yeah, Novak would have the market cornered. They are the only ones I can think of that maded a 550 sized motor in a high kv configuration. They were originally designed for the big heavy E-maxx monster trucks and didn't work so well using high voltage lipo batteries (4s). But they are perfect in a 1/10 4wd SC truck which can run them and these motors have plenty of power, tons of torque, run ice cold, very forgiving regarding gearing and put out enough rpm's (because of the high kv) to run on 2s lipo which most tracks require for racing. Castle and Tekin do not make high kv 550 size motors. Unfortunetly Novak has discountunued the HV 4.5 (which was the only high kv version) and now they are hard to find. Novak please bring back the high kv 550 motor.... I have one in my Jammin SCRT10 but I need another one for my Traxxas Slash PE 4x4..
