645 past 2 min is not recommended. Temps were high after a 4 min run. 2 min is still under 130. Pretty warm out here in CA. Those in cooler climates may be able to swing the prop with less heat. 645 on a stock motley crew or the mystic with the 1800 kv would likely be too much prop. an m445 is probably max there and i would recommended back cutting.

If i get a chance i'll post some charts from the runs. Tried to keep it from getting too cluttered. Temp probe was around the motor wires where they enter the can. Actually surprised the motor made it back.
