Evan-RCU and mrasmm both are abo****ly right. The DX6 is NOT a full range radio. Whoever told you this or wherever you got that information, it is wrong. No offical Spektrum website will tell you the DX6 is a full range radio. I agree with Evan 100%. You are taking a chance by flying your helicopter, or anything other than a parkflyer, with a DX6. I know there are people out there who do it. And just because you have gotten away with it on a .46 seaplane, doesn't mean you are going to get away with it on everything else you fly. I am not going to sit here and try to convince you that you shouldn't do it. But I will say that I think you are risking your investment, and the saftey of others as well as yourself.
