Thanks guys. I know it's possible to learn on a 3 channel and then transition to 4 channels, I did it. If I can do it, I would think anyone can. Since I know we get the occasional cross winds at our field, I can see an advantage in having ailerons. Also, if shredder is like the typical young students these days he'll learn quickly and ailerons will give him more options for fun stuff to do. Wonder how long it'll take before he's wowing everyone at the field by doing rolling circles with it? I'm leaning toward suggesting adding ailerons and reducing the dihedral a bit.

Oh, and a good 46/47 is a definite. It's kind of funny, Tower suggests a .40 LA. I'm not one of those anti-LA people, but an econo .40 isn't terribly useful for future planes.
