RE: What TX do you fly with? 10X vs. 9Zap
9ZAP has flight modes and has since before the "WC" versions. The extra channel may or may not be an issue depending on your configuration. JR plays nicer in a buddy box situation as long as both transmitters are exactly the same model (SX, etc.) (things like master retains trims, etc.) I find Futaba programming a bit easier but it may just be years of Futaba experience.
