I've run a few of the EDF foam planes and learned some about cooling. The Dynam Me-262 has everything in the fuselage and stock it had no cooling holes, I just opened the gun holes and cut a small hole in the bottom of the fuselage behind the wing. Prop planes are much less demanding on batteries and ESC's, although cooling air is good. Most have a hole of some kind in the rear fuselage area and a small intake in the nose so that air moves through the plane. I may take a window out of the nose "glass" so air moves through the fuselage or just make a small intake in the bottom.
What plastic parts do you have for this plane, I have the cockpit kit but not the superchargers? I vacuum form plastic parts and I could make my own, but if you have some uncut pieces I could copy them and send you a new set.
