RE: Ziroli Bearcat engine
Kevin,
Flew mine for years on a Q-52 and it was (Monokoted) up like Howard Perdue’s #14.It was light coming in at 26# but the speed was on the nose. You will probably have to have nose weight like all of us have.I had to add 2 # to the Bearcat so a G-62 or Q-75 that has some weight to it should be great. I am finishing up a new Ziroli Bearcat now and am flying a Ziroli Hellcat that weighs 42#(9# of nose weight) on a G-62 and have been flying it last year on a RCS 150 ( a good friend of mine owns it) and it is a match to the Hellcat.
Good Luck Todd
