Big price jump from dx7 to dx8... about 260 to 460! I don't think that I can come up with tat kind of money unless there is a big difference. What makes the dx8 so much easier to program than the dx7? It's been 35 years since I have had anythig to do with RC...So much has changed! I have read the ads in the hobby mags for both, but they don't go into much detail.
