The AR6200 is a full range 6ch RX with a satellite receiver that is designed for use in nitro planes/helis.
The original one that I put in my heli has never given me a single issue in almost two years (again, only using a 6volt NiMh pack), it was just the knock off (fake copy) one I received off an online auction site that caused the ONLY problem I have ever had with my specktrum radio gear, thus my lack of desire to ever take shortcuts by saving a few dollars by buying of auctions again - it's just not worth the risk.
