I skipped the fun fly. They had all the donuts they wanted.

Codiddley was just here, he thinks the plane is large enough for a 20-30cc engine. After assembling the parts for some bench flying, I think he's probably right. [X(] I flew my last LT-40 with stock wing and slightly improved control surfaces for about 6yrs with a Tower .75 engine. It was very sporty, but it would not hover. It would do very slow tail slides at full throttle. The current version that I'm working on, with the increased wing area and larger control surfaces, is surely going to be heavier than a stock LT-40. The TH .75 engine - even with a pipe- ain't gonna make it hover at this altitude.

I'll have to start looking at small gassers. The firewall is narrow, so I need an engine with a pretty small foot print. I'll add another piece of 1/8" hard ply to the firewall and pin it.
