Wondering what to do.... there are several different models/kits I am thinking about but here is my question. Does each model fly a little differently or all pretty much the same? I guess what I am saying is, if I purchase model A and get proficient at flying it and I turn a decent time through the course, but would a different model fit my flying style better and make me faster through the course or do they all fly close enough to the same to not matter? I guess one would never know until you tried several planes....
