BW, this is the Coincidence Of The Day. I had read somewhere that you had a Butterfly. Knowing from a different thread that you have several planes with smaller than recommended engines on them, I was going to send you a PM and ask about the BF. Then I changed my mind and posted it in the kit forum for everyone to read and comment. A couple of hours later you have posted the first reply! My reason for considering the .10LA is that I want to use the smallest engine that will fly the BF reasonably well. If it can climb to ''thermal altitude'' before it runs out of fuel, I'm happy with it. I definitely see your point about adding weight to the nose. Normally I would rather add engine than lead. OTOH, it would be very interesting to see if this big airplane can get in the air with a .10. Maybe a 15LA will be the best choice. I have a 25LA, but that will probably be too much power.

tailskid, with the .20 engine; would the BF keep altitude at idle? Is it possible to land it with the engine running? Most of my landings will probably be dead stick after a long glide, but you never know, this plane might be fun to do touch and goes with.
