I am right there with you on the overgearing. Use higher voltage, spin the motor faster, gear back down and it will run better. Plus the various pieces of equipment will run cooler. I see people trying to get a cool system by running a 10xl on 4s, gearing for 40mph and then wondering why it runs hot. Too much load!
