I have had my H a little over a month now with over 100 flights. I am starting to see some wear and tear on some parts already. A couple of my prop arms are getting a little sloppy, not much but enough where I am starting to see a jello effect in the video. After inspecting the prop arms I see it is just a screw going through a plastic hinge and the fit is no longer tight. Now one of the fans in the ST16 has started to make a screeching sound like the bearing are giving up. One of the legs on the landing gear keeps sticking and I have to raise it up and down a few times to get it to lower or retract. I have not crashed this bird yet or even had a hard landing. I think there are to many moving parts on the H and it's long term durability is questionable. I will call Yuneec and see what they say, might be time for a rebuild. Anybody else seen any problems not related to a crash?
