I own a 40% 3W 330S with a QS 150 on it for power. It happens to be the plane that I have the least flights on for various reasons, none bad! I also fly a kit version of the 105" Aeroworks Edge, and a 40% Carden Cap. Since I'm kind of new to giant scale, I accumulated my mix of planes and flew all of them a little. Here are some of my observations. Each of these planes has its strenghts and weaknesses. The weaknesses are more style related than design related. By that I mean that the Cap is a wonderful 3D go kart. It likes to get tossed around and is an all around hot rod. The Edge is sort of inbetween the Cap and the 330 as it's pretty good at precision, and better at 3D. This is the plane I get the rust out with in the beginning of the season. The 3W plane is by far the best at precision aerobatics. It is the smoothest out of all three. I really haven't had the time to fine tune it for 3D as the Edge and Cap have kept me busy at that. 3W is a more popular IMAC than 3D contender from what I've seen. Don't get me wrong, they will hover and harrier with the best of them, but it's strengths lie in precision in my opinion.
As an aside, it is also the heavier of the two. The Cap is 36 pounds, the 330 is 40 pounds. Although I am a "lighter is better" freak, there's just so much you can do to a composite airframe.
My wings seem god awful heavy compared to the others though.
Possibly there is some fat that can be trimmed there.
There is a lighter version available from the manufacturer if you desire. On every occasion, I have had positive experiences with Aircraft International and their staff!
Whew, did I answer the question
