I assume that you mean 1:7 after the FP gearbox supplied in the kit. I can't answer that conclusively without knowing the properties of your arm. Our team always calculates for worst case scenario, which would be in this case the arm being horizontal and fully extended with a full load (We would never do that, but the arm should withstand it very briefly without burning motors).

A heatsink and fan will cool the motor case but not the wire coils in the motor(at least not directly or fast enough). It will help but not as much as some think. Increased air flow through the motor along the surface of the coils is probably the best thing for this situation. Not sure what the best way to pull that off is. Any suggestions?
