Looking for a powerplant for a new plane and im undecided to go with the 10 or 15cc ggt
The plane is the G.P. Chapman 580 Eagle 46 81. Wanted it and got it for a great price.
All up weight at 6.10 lbs with this engine
http://www.osengines.com/engines-air...982/index.html and a 14x4 wide apc prop was reported to have very good power. I can get it lighter and would like to do so with using the 10cc instead of the 15 and some other components.
I'm just not sure how comparable the 10cc is to the fs 81. Listed horsepower the ggt 10 is a bit more than the fs 81
I like the power of the ggt 15cc but its a little heavier than i'd like.
The plane will be flown with a mix of aerobatic and some mild 3d.
T.I.A. for some help for a newbie to gasser engines.
