Busa D8 has a short maiden
This is the second one of these I've had, but not built. The first one had a G23 and was a little heavy, but flew great. This one had a G26 and was a little lighter. The guy I bought it from said it had flown once, but as it sat it was a little tail heavy. So I moved some batteries around, added some weight in the nose, and a few other small things to get 'er ready. I measured the wings, and they were square within 1/4 inch of the vertical stab, and appeared to have the correct amount of washout. Wing incidence, while not measured, was eyeballed and appeared to be correct. It balanced where the book said it should, nice and level. Just like my last one.
Engine was run up, controls checked, and out we taxied. It came up on the mains just fine, rolled along untill I gave it elevator and off she lifted. It climbed and climbed, and while I was trying to add some down trim it began a turn to the left. I quit trimming and tried bringing 'er back around with the alierons. They don't have a whole lot of authority, so I got on the rudder and that brought her around quickly, but also dropped a wing. And not the outside wing, which I would expect from adverse yaw. I got it back level, and tried turning again, but that resulted in it snapping, and there just wasn't enough room to recover.
It landed in a tree, and I didn't get a pic of that. The wing was seperated from the struts on one side from what I could see, and when I shook the tree they came down seperately. The left side wing strut was still attached to the wing, but the aft strut upper attach lug was broken. The r/h wing strut was not on the wing or in the fuse, and both the fwd lugs were broken. The strut's lug wasn't broken, but it was, for lack of a better word, unbent. Don't know if that happened in flight or in the crash, but I'm wondering if it didn't happen in flight. The struts looked to be soldered well enough, but one never knows. I certainly didn't pull any "gees", at least not intentionally, so I dont' know.
Anyway, the fuse broke when I tried catching it, and the wing was split on the trailing edge. It's possibly repairable, but I'm not going to make the effort. The carcass has been stripped and passed on, and the G26 is looking foward to its next home. Another D8? I guess I really should build my own this time....
