rcjon, I still have the stock foam wheels on my Edge. I haven't had any problems bouncing it at all. As a matter of fact, most people who I have shown it too think they are rubber and actually have to touch them to see what they are like. I am not a superb lander, but I manage to get them on the ground in one piece most of the time.

P.S. I forgot to mention, they save alot of weight over the rubber ones also. And, they have held up very well off even the rough surfaces I fly off of.
