Hi, this was raised in this
http://www.one18th.com/forums/showth...t=47100&page=1 thread at one18th.com. mOOse reckons that the stock Baja was better than a Novak Spy, as it is the same ESC used in the MLST which runs 2 motors, so any upgraded motor would be fine with the stock esc. Orion's Baja would be no problem as it was designed to run with stock electrics of the mini T. Hope this helps.
If you are looking to upgrade your esc I'll take the stock Baja esc off your hands.
