RE: More Skymaster quality issues .. Check your wing ...
Wojtek,
I feel your pain. I had many issues (as did others) with my Skymaster/Xtreme-Jets Dragon. Shipping damage, poor wing repair done at the SM/XJ factory (after a couple of flights a crack in the wing developed. Split S went to fix it and found a huge area of damage that was filled with some type of glue making an inferior attempt at a repair), lack of hard points for control horns, lost canopy (which SM replaced in a week) which was due to an impropely glued windshield so high pressure air got in and blew the canopy off, cracked windshield and improperly glued aluminum wing tabs. It's a shame.
Luckily you caught your problems before it blew up in mid air! And hopefully your information will save someone elses airplane!
