Well, if you pulled up Aloft Hobbies you may see something you like. I fly with two guys that are using there systems and have been for four years without a radio glitch. I think there 16 channel is about $175 but they have a lot of selections for all your needs. I just started using there receivers, about 1/3rd the cost of any of the others on the market.
Should be enough choices to get you going. The FrSky system is a pretty good choice. It's a clone and I'm sure they ripped off all the other manufactures designs and research. Copy Right Laws?? I don't think they care.
