Yup, second that. My Bixler spar is working perfectly stock. I've probably pushed mine a little harder than I should have on occasion (mucking about in the air with glydr's weakly powered parkjet to name one example) and no issues yet. Hell, this thing's been flown into a tree and had rocks, cricket balls, sticks and pinecones thrown at it too.
The only issues with the plane are the control horns (see any Jpower/Sky Angel plane) and a lack of threadlock on the motor mount.
I think the guys on the show have tact when it comes to faults with stuff they test - if it's pure awful, they don't show it (what would be the point of that???) and if it's got a few little foibles they'll fix it. I don't know how many times I've heard about people complaining about quality and CS of HK stuff when the fix usually involves some minor fiddling or another $2 part. I like the 'fix it and make it work' philosophy that the show projects - I wish there were more people like it in the world.
