I have the Aeronaut Panther. I have decided for cost reasons to use the Midifan.If I use a 600 size brushless as recommended ,how do i provide for cooling as there is allmost no room for airflow around the motor casing. 1 to 2 mm in most cases. I want to operate around 1000/1100 watts so heat build up is a major concern.Since the fan is not carbon fiber the temp could deform the motor mount. Should I downsize to say the Kontronic 500-19 and would it operate in this range? What do you guys think??? "The Bates"
