The Sm 339 is a very nice jet......quality is good.....the landing gear is awesome....I am not at all a fan of the chinese machining quality we normally see.....this gear is the exception.....Anton got it right.....good quality metal as well, which is key to the success......I've seen several different sets take less that perfect landings on various SM designs with no problems.....the plane flies very nice....very smooth and it presents well in the air........FWIW....
