My first and last computer radio?
What I meant is that like your self, $$ makes a difference in my decisions. The Tracker II is comparable to the 9C/8U, but has a few extra capabilities for less $$.
I don't know what "servo display" is either, but I assume it's a graphical representation of the position the servo SHOULD be in for the current stick position. Whoop-dee-doo :spinnyeye
P.S. Some people say they've flown for years and never had to change channel. Good for them. It's happened twice now that a best friend and flying partner buys a new radio without checking my freq. In both cases he was on the same channel as me!
