RE: to imac or not to imac
when i started i had a greatplanes .40 size extra and i did prety well. a 1/4 scale (or so 70-85" wing) would be your best bet. i am now flying a 25% aeroworks edge.
my sudgestion would be get an airplane you like and are confortable flying. than go practice. thats all there is to it. good luck!
p.s. where is bryan, OH? because i live just north of columbus.
