Man, you got 10K worth of airplane there, tons of flights on it. Why not bite the 250 clams and get 2.4 and be done with interference issues all the way? I've got four jets flying 2.4 and setup three others on it. All are worry free flyers, my F-86, I didn't even range check it. Flew as far as I could see it!

This stuff is that good, IMO.
