Yes, I do... but it will be interesting to find out how it does. I don;t know if anyone has pushed these motors to the limit in something like this. I know a guy who ran a basic 4200 motor in an emaxx and it did 40mph+ but ran hot. The 5700 setup may be very fast if done right, but it will be limited to short runs, imo.

A back-of-napkin estimate says that if you gear it 9/46 it will hit 50mph theoretical. I don't know if the little 5700 can do that... but it will sure try. That's why it will run hot... it's being overloaded.

The only way I see it doing ok and not overheating too quick, is if you gear it even lower... so it tops out around 30. That will take some custom work... large spur, truck diffs, etc. Even then the high revs will make it run pretty hot, but it should work.
