It hasnt been above 32f (0c) here, and but for the cheapo landing struts, the copter loves it. I checked the motor temp after 5 min, barely warm... after 8 min, warm... after 9-10 min it is just getting hot enough I can touch it and tell its been used. Thats with my home-brew'd catfood can heatsink.
I got a probe style thermo I think I will adapt to the copter, as in install the thermister on the motor case so I can get some real data about 'rate of rise' and 'peak temp' ect. I am betting the low outdoor temps are helping, as I have just as much power after 8 min as I have starting.
Again I dont fly like a 'bat outta hell', I putt around. The brushless mod isnt on my 'gotta have' list quite yet.
