I should have been a bit more clear.  I plan on learning excusively on 4 channels.  I like the idea that the avistar can handle wind better, and has the ability to be fairly acrobatic once im ready.  As far as flaps are concerned, they can be locked to make them inoperatable.  At some point in the distant future, when i want to buy a plane that flaps would benefit from, I can always break out the old trainer and learn to use them on a more stable plane first.  It comes eith a radio thay can handle it, although not a very good one from what i read.  Great engine though.  Rtf is the only option right now
