RE: Selecting a 6 CH radio, Which one??
If money is no object and you want a nice radio you can use for a long long time, look at the JR 9303. At Chief Aircraft you can get one with a synthesized TX module and a synthesized RX and 4 x 811 digital sport servos for $599.
If you want a quality radio for very little money and you don't need any more RXs or servos, you can do like I did... I bought a JR 8103 for $369 from Chief (free shipping) and I sold all the stuff that comes with it for $200... so I got an 8 channel radio with curved mixes, 10 models, 3 aircraft types, etc... for $169. Can't beat it anywhere.
