Hi Emory,
My understanding from previous posts is that you won't get adequate cooling if the airframe is stationary or you have the motor on a test stand. Assuming reasonably good ducting on your plane, the motor will run a lot cooler in flight than it does on a test stand. For some strange reason, this actually makes sense to me but I'd be hard pressed to explain it.

Hello,

I was wondering what is considered to be a normal motor temp after a flight? I have just started to "break in" my batteries by running the motor. I am seeing my motor at 120-130 degrees F after running two 3 minute periods at half throttle. At what temperature does the motor get damaged? I am running a Plett 30-10, phoenix 85hv and Tanic 5s2p packs. I hope I will finally get this plane in the air this weekend, if the rain will hold off.

Thanks,
Emory.
