I have both adx6i and a dx7 if you are unshure about wheather or not you really want to fly and are on a budgit the dx6 is ok but if you are committed to fly and will move on to bigger and better then a dx7 or dx8 will work for you much longer. the dx6 only holds 10 models 20 for the 7 the extra chanel is very handy also. If money is no object I think I would go for a JR 9503.
