This Slope Scale kit can be made to resemble a P-39 Aircobra or a P-63 Kingcobra. I use the terms interchangeably for better or worse. My plane leans towards the Kingcobra if only because I opted for a more Kingcobra like vertical fin because it is a bit taller. I figured the extra stability couldn’t hurt.
My current P-63 is a standard layup and with normal balsa sheeting/solartex/paint type construction. It is flying at 38 ounces. I recently picked up a heavy layup short kit that I will build heavier for the big wind days. I am going to use 1/32 ply on that one.
