You asked about the durability of the Mini Ultra Stick, and my honest response is that the question is thinking in the wrong direction. A better handling plane will avoid crashes, which is the best way I've found to survive them. Your landings will be smoother and more predictable, and the plane will not be affected as much by wind gusts. As long as you have a smooth enough landing strip for the wheels to roll on withing binding or bouncing, you'll find that landing a stick (any stick) is an exercise in relaxation. That said, if you pull a bonehead maneuver and drill it in you will take it home in a bag. If you really want an indestructible plane that's fun to fly, I'd recommend a Parkzone Stryker. It can cruise as low as 15 mph and tops out around 70 in stock form. You can make the throws as hot as you want to as you get up the nerve, and since its a belly lander about all you have to do is flare it and try not to bring it in nose first. The Stryker is my park plane and general "don't worry about it" flyer. I've flown it in gusty 25-35 mph winds with no problems too.
