I never said it can handle, I said its rated power was good enough for 10.5. The software which drives the motor would have to be devloped. A 380 motor and 540 motor require different programs to get the most out of the motors.

Novak is aware that the Footprint on their GTB's is a little large for the 1:12 scales. They developed a Mini scale 380 system that based on power capability can handle maybe some of the stock brushless motor in 540 size. It would be awesome if there was 540 mode in the Mongoose for those who race just the stock/super stock brushless classes. I would assume Novaks approach would not be to bridge 1:12 and 1/18 scales with the same ESC but to Bridge 1:12 and 1:10 scales with one ESC. The reason would provide a more powerful esc that can be used in 1:10 sedan and 1:12 with any motor. Since my XBR could not handle all the motors I may use, I upgraded to a GTB in my sedan. A modifed Mongoose system would also limit motor selection so not ideal for all racers. But most of my 1:12 racing was done with a 13.5 motor anyways so I would consider a smaller system even if it limited my racing option to 21.5/17.5/13.5 and 10.5 motors. The current 4-cell GTB i have takes up too much space IMO but I did make it fit.
