I'm using MEGA ACn F3A and it it is fairly hot around 70-75 degree C, manufacturer says it is no problem and it seems to be ok. Running a Mejzlik 22x12WE prop.
At the moment we are facing high 20 temps nearly 30 in the shadow, in the sun more like 40-45 degree. You must expect something similar in Portugal during WC

During my practice my motor is coming down about 60C or 140F. Usually with in 10-20 minutes I'm ready to fly again with the motor down to 110 degrees.
