I got had the PAM Edge, very nice to build and nice to fly, mine had a G90 and it sucked, my pal put in the SA100 and it was good stuff, I got a YS110 and if you put that in it will be NUTZ!!! Go for the PAM Edge, the Aeroworks one has some structural problems, they may have sorted it out by now. The 1 piece wing caused the fuse to be weak at the point where the 2nd former is, or was that on the 40 sized plane? I forgot.
