I basically agree, except that I don't think the OS .40 LA is a very good buy these days. I'd prefer the TT .42, which is also a plain bearing .40 of about the same size and weight. I also think the TT .36 or similar would work well. It has more power than needed, but it is as light as the OS .40 LA. Learning on this plane is going to require a buddy box, so I don't think some extra power will be a problem. Definitely keep the rubber bands rather than nylon bolts because they give more in a bad landing. Jim
