ok, that all makes sense and thanks very much.

I'm assuming based on the comments that the futaba radio I mentioned isn't all that great. The DX6i seems to get better reviews.   I am leaning toward getting that mustang kit,  with the DX6i and engine, simply because I like mustangs and never had one to fly before and I do not have a .45 engine at all, The engine in that kit seems to get good reviews as well.   I understand about getting as much radio as I can,   I also know that I will doubtfully ever need much more radio than the DX6i in that kit based on what I flew in the past and what I wanted to build and fly.   So the next question is,   Is the DX6i  a radio that is reliable? 

If not, what radio would any of you suggest.   </p>
