Paul,
Not sure what I said or did, but you're very welcome. [sm=redface.gif]

I don't know that plane or that engine, so I can't help with particulars, but it sounds like you're getting help already. That 11 X 7 (or an 11 X 6) should work well.

Good luck with the first buddy box flights. Just try to relax, the tense fingers and shaky knees are the worst part of the first flights.

Hey Yub,
It was good to meet you at the club field last weekend. Hope you enjoyed the scale fly-in.

A standard LT40, or the Tower Hobbies Trainer 40, ANY trainer is capable of quite a few aerobatics. They'll be capable of loops (both inside and outside with a 46), rolls (well, barrel rolls), spins, stall turns, split S's, Immelmans, rolling circles and inverted flight. Many of them won't be pretty, or they won't be terribly precise, but your control inputs won't be either.
