I'm thinking of putting a O.S. .25 LA-S C/L w/Muffler in this plane. It seems like it will build up light with the wood supplied. Is this a good engine choice for this plane? And how does it balance out? Any recommendations or thoughts?

Mine balances out fine with a Fox 35, dont' think an OS 25 would be any problem whatsoever. fact is, I was thinkin of swapping engines when I get back to flying CL again. It's a fine flying plane and I need to order one of each of the series, the String, Buster and Cosmic Wind.
