Thanks for the input.  I fugured I was on the right trackk with the radios, but I am going to check into the whole sd card thing.  The cessna has flaps and is 5 channels, so i thought 6 would be safe, but I will also check into 7 ch radios. 

And thank you Jester for your input on servos - I was going to go out and replace all 9 servos in my foamies with ball bearings because I thought somehow they would be better - saved me a couple bucks there.
