I'm new. Not too many budget restraints, so I'm making mistakes left and right. Bought a RTF trainer that included a 5 channel computer radio. So far so good, it's all I need right? Then I wanted to get a SIM to practice on. Got a 6 channel computer radio with FMS, a billion planes, buddy wire, and USB wire to run the sim with. Now I've got way more than I need right? So today I bought a nice ARF because I wanted to try and build a plane. I got a nice little Ultra Stick 40. Guess what? If I build it with the flap setup it comes with, it says I need a 7 channel radio... [X(] I can see an 8 channel on the horizon already, and I've only been at this 2 weeks. Sheesh! - Joe
