Engine cooling

One of the problems that was encountered last summer was the motor was running too hot. Experience with these motors by other owners was that a baffle would help. I was hoping not to have to do this but have decided to proceed as the motors is too valuable to risk and a dead stick on a 55 lb plane not for the faint of heart if you know what I mean. It is in aluminum right now but to save weight I will cut it out of 1/8 inch light ply with a layer of light fiberglass on either side.
