Ah, A question I think I can answer. I have the aeroworks 33% edge. They call it a 33 but compared to everyone else's 35% it is very similar in size. It needs a good 100 twin to get the most out of it. It is a great 3-d plane, and will also fly normal aerobatics very well. I absolutely love mine! I also own the H9 33% cap, and have flown the extra. These are good planes, and 3-d well. The biggest advantage to these is you can get by on a zdz 80 which is quite a bit cheaper. These plaens are awsome performers, but I feel the aeroworks edge has an advantage over them. Eithere of these two planes will serve you well. It really boils down to how much you want to spend, and which one you like the looks of more. Everyone that has flown my edge, comments on how slowly it lands, and how great it flies. Good luck with your choice, and I would pick the aeroworks edge over the H9 extra. But if I were going to get a 35% carden I would get and Carden Extra over the Carden Edge, due mainly to what was qouted from what Garret said!
