Both radios are nice, and the 10X is a much more "premium" radio with titanium case, etc. But it is an older design, and you have to add a module ofr 2.4. I recently sold my 10X and bought the 9303 on 2.4. I am very pleased with it. Has model match, so you won't take off with the wrong model number loaded in the xmtr. I also like the fact that I can fly with 4 receivers in my jets. Check that one out too. Bob
