RE: Who Sells More Transmitters
I don't have any industry stats but, all you have to do is look around or ask the local shops and you will realize that Spektrum clearly dominates the market with the most share. The local shop has told me that Spek outsells Futaba 10 to 1.
You have to hand it to them, they've been on the scene for about 5 years and have clobbered all the other players to become #1. Futaba guys can cry all they want about Futaba being a better product but, it doesn't matter; people have voted with their wallets and Spek is currently the winner.
BTW, the connection between JR and Spektrum is that JR licences Spektrums RF technology. Spektrum is owned by Horizon Hobby.
