Well my biggest thing is cost and simplicity. I like things to be simple. I know this isn't a hobby to be broke to start with but I'm broke because I'm addicted lol. Right now I've got 1 radio, 1 receiver, 8 servo's, 2 motors, and 5 planes lol. I've got a GWS Zero which is fun, a Sig Kavalier, a Strudy Birdy 2 that I couldn't resist because he had it marked so cheap, a Sure Flight P-39 that I couldn't resist that I got off ebay for $39, and a Sophisticated Lady glider. I want the 6 channels because I'm a warbird person and would like to be able to have retracts and flaps, plus my glider needs flaps. So after looking around I may go with the Airtronics but can anyone tell me if it will allow me to mix the flaps with the ailerons? I've heard of people doing this with some radios. It droops both ailerons like flaps but still gives you some aileron control without having to double your servo's and split control surfaces. But as I said the biggest thing is price and for $109 without servo's the Tower Hobbies one caught my eye but I'll look around. Thanks for your suggestions I'll look into all of them and see which one I like.
