RE: Radio most used at events?
iIdon't know which one is used most. It really is just a personal preference as both are good systems. I like my JR because its easy to program. I'm sure there are others that would say Futaba is easy. Just what you get used to. I have heard that the digital servos that come standard with the new JR radios are of a better quality than the ones that come with Futaba but that is just hearsay. I can't be quoted on that.
Bottom line: Either way you choose, you will probably really like the radio.
