Sorry my example doesn't really match your project but thought I might encourage you to hang with it. Nearly 19 years ago I started tinkering with this 80" one. Had a blast exploring and overcoming different design problems (started out as a tail dragger !). Started out with a K&B 60 but have used a Fox .74 for most of its life. Last year I installed a 1.20 4c but haven't got around to trying that config.
Certainly have to agree with CP about the very different looking and feeling manuvers possible. Coolest flight to date was when one aileron pulled free and was dangling by the pushrod. Made it down with no problem and had decent right and left turning ability!
