Wow, talk about recuring issues. I got mine back in July of 2012. Skylight leak, check. Fixed it by tighting the screws and leak stopped. Leaky grey water, still have.
As far as the landing gear, I had to have the gear box replaced. The motor was working too hard and is drawing extra amps and that is why the fuses keep burning out. After they replace the gearbox I haven't had an issue now for a year.
