I found that high RPM motors are best for wide open tracks where you are full throttle more. A torque motor is good for when you tracks where you are on and off the throttle a lot. You can gear a torque motor for wide open tracks, but I have experienced them getting hotter when wide open.
Gearing down will help get more torque. It's a think where you have to calculate how many RPMs you lose tuning down to how many RPMs you gain when gearing up. I just thought of another video I should make. LOL....
