Ive been flying on airtronic rds8000 for about a year now right as the bnf have been coming out,, the only issue ive been coming upon across is there are alot on bnf that are coming out that I like to purchase but my rds8000 isnt compatible with some of bind and flys. So I purchased a dx5e that works for some of the bind a fly. My question is what radio should I purchase so I can fly some of the bnf that require more channel and one that I can set up expos on?
