Hi Matt!
Thanks for the tips. I run touring cars.
I really like the powerband of the 4200. Very driveable

The 5300 is a little too fast for me to handle
Gearing up increases amp draw from the pack. This is where the risk of overamping of the pack occurs? I have been told that this might cause damage to lipo packs. What's your take on this?
Cheers!
Alan
