Thanks Greg. I was just doing some measuring, its seems like running one 30mm fan diagonally on top of the motor might work. The screw holes diagonally on each bulkhead measure about 42mm apart. Close to the measurement of the holes diagonally on a 30mm fan
Also, a separate newb question. I have experienced advances in the esc technology after starting this year with an LRP Sphere and now having a Tekin RS. I currently run my friends used Duo 13.5 motor. Does anybody know if there is an amount of normal usage time or whatever, where a brushless motor will start to fall off performance wise ? I am thinking about trying a new motor. Are all good 13.5 relatively the same performance wise? I just dont want to get a certain one, and then find another is superior or...... Kind of like the esc stuff i guess.
Dont kill me-Is a Duo 2 better than a Duo?
