Tall gearing reduces torque- you need lots of torque to do backflips, and the Erevo doesnt backflip as easily as the emaxx as it is. Tall gearing (22/58 on 6s with ?kv motor again?) will also work the esc harder as the motor pulls more current when geared taller- hence the fan coming on for short periods. 60mph isnt an everyday setup for an MT, 40-45mph would be more sensible and the esc would stay cooler without the fan needed to come on. If you want to backflip, I would lower the gearing, lower punch control, and increase start power; if you have the extended wheelbase rear arms, loose those too.
