You should always allow at least ten minutes in between flights if you have more than one lypo. This plane is fast enough that it receives plenty of incoming air especially when doing aerobatics such as loops. I havnt had a prob with it but I guess if it happens to you, well you know how to solve it. The esc is located right behind the fan on the upper portion of the fusalage two inches back. It is cleverly positioned so the esc stays cool at all times..like its own radiator. If you want the fastest, cheapest edf, get the F-35. It dominates and cost the same as the f-4. Out of my 1300 mah lypo..with good rationing of full throttle limited to low passes and loops...7-8 min give or take and gives you enough to circle the pattern again if you overshoot. I just received my 1800 mah lypo which should bump that to 10-11 min.
