I've been on 35 mhz for years with RC planes, worked OK but long antennas are a pain , especially with flying wings, so I finally bit the bullet and went 2.4 Ghz. I saw the Flysky FS i6 complete with a rx advertised for just £35 I think it was. I'm more than pleased with it. Range is good, set up models is easy. It has fail safe, 20 model memory. What more could you want?
