Use the xmaxx heat sink

I have the same motor and heat is a problem even on 4s. Using a rocket 4092 1650kv now no more heat problems. I got mine from amazon for less than a 100 bucks, Its a torque monster!

Wanna get rid of heat issues? I run a 5687 max6 no fans or heatsink. Will do 70mph and stays as cool as a cucumber

I was just wondering saw that it was a 46mm diameter. Right now just tested the max heatsink with a fan screwed into the grooves of the heatsink. With just the heatsink on a 17t pinion the temperature was 168 degrees. With the added fan my temps were 107. Now what size pinion?

Snag a 40mm fan at some point and aim for 24/46
