Well, I have a Giant Stik that is a pleasure to fly even though it is heavy, because of it's high wing area. I have a Katana that's a pleasure to fly because it has low wing area, but it is light.

Then I have a Giles that must be flown very carefully because if you get it too slow or pull too hard on the elevator, it will snap on you. It has a Homelite on it, and about 900 squares. Warbirds are famous for high wing loadings and the tendecy to snap roll. That's why it concerns me to put a gas engine on a Zero with only 877 square inches of wing area. Your choice, but it is always a bummer to build something that isn't enjoyable to fly... (Or to lose it in a crash due to a snap roll in a turn or final approach to landing.)
