RE: Savage FLUX XL HP - Gearing Wheel/Tire Question?
Are you running the 44T spur? You run 6S, right? If so, then gearing down may be wise; drop a notch or to on the pinon and maybe go up to a 47T spur if needed. Don't let the motor and ESC temps get past 150-160. I learned that the ESC fan switches on at 170 and the system shuts down at 190. As long as the ESC fan can still switch off occassionally and not run continuously then I'd say you're OK.
I know you already have the GSTtires available which is why you when that routebut, I am interested in doing something similar with my Flux except I'm looking into using 5B / 5T tires. Basically, all one has to do is swap the hexes to what; 23mm is it? The same axles should work, right?
