Sealed Against Sand

Jake's Note: A PSS sloper, A P-51D, like the Ki-61 it has a rudder and spoilers. All balsa and ply and has a 54" wing span. I made the left engine exhaust movable and pinned the on/off switch to it. I can move the exhaust back and forth to turn the radio on and off. Sand would get into everything and render the switches inoperable unless we protected them inside the fuselage. This solution not only looked good but really works.
