About the landing gear, I use the stock landing gear (ie bent) and found it very adequate. Almost no tendency to bounce, and when you slam the plane the landing gear takes the hit, the airframe remains undamaged, at worse you need to straighten the landing gear, no big deal.

Now that I have moved the CG aft though, I find it tends to bounce more than usual. I will try to flip the landing gear (ie front/rear side) so that the wheels get a bit further aft. That should more or less follow the CG change... we'll see...
