Hahaha, I like your theory Bmatthews...... no wonder all the pretty ones end up in small pieces. [sm=lol.gif]
Papa, as far as your upthrust you better change it to downthrust for the flat bottom wing or maybe you can get away wtih zero thrust when using the semi-symmetrical. If you leave the upthrust as it is your model would want to balloon as soon as you add power to it. What could be interesting is your slow speed might get slower from the added vertical thrust vector component. Instead of an ultra fast trainer you could have the slowest landings out there.
