I have used in the past JR, HITEC, WORLD, AIRTRONICS, AND FUTABA.
I Started with FUTABA and end up with FUTABA after 14 years in the hobby, the 9Z is one of the best radios, I had the 8 ch. before and I really like it but with the 9Z was love at first sight so I went ahead and bought it, I almost buy the JR but that's when FUTABA released the 9Z with the new features.
