RE: Looking for Engine Suggestions for Royal F8F Bearcat
Scale tailwheel on this 62.2" span Bearcat would be 1.533" or rounded down to 1.5" in diameter.
This plane will require tons of lead in the nose to balance, and the RCV 120SP happens to be the heaviest 1.20 size four stroke engine available. We are building a couple of Top Flite 60" span F8F Bearcats, and I will be using an RCV 1.20 in mine, swinging a 4-bladed prop. My second engine choice would be a YS 110FZ since it fits nicely inside the cowl with just half of the black valve cover sticking out.
