So, if you have the small one (Avistar???) spend your money on a nice 6,7, or 9 channel radio then. Just another idea to keep your head spinning I recently got the JR XP9303 2.4 Ghz Tx and it is so nice not having to worry about getting that frequency pin every time I fly and I have more functions than I will ever use... Uhm... I said that about me Futaba 6eax too... well it will keep me happy for a few years anyway
