Billy, I have flown both and they are great in different ways. The aeron has great capabilities and if you have a kit, build it, you will not be disappointed. I am not sure when the sledge arf will come but it will. I need to pressure Robert some more for that . But if you do not mind building it goes pretty fast and it too is one you will not be disappointed you built. Heck, you saw mine fly at Memphis you seen what it can do, now imagine if someone good was flying it. Jeff Williams
