I moved the cg to 70mm from the leading edge and it seemed to help the snap tendency at slow speed. I made a fairly slow landing and she did not snap. On my second flight, I made some aggressive roles and a few loops and it seemed OK. It did act a little strange when I came out of a loop. I brought her in refueled and took her up for her third and FINAL flight. Unfortunately, that strange tendency on the previous flight was actually a tip stall. On this final flight I performed a another loop, fairly high, but it was fatal. Near the bottom of the loop, she snapped, went into a spiral and I could not recover. She went in nearly flat but almost straight down. With the fiberglass body, the results were devastating!! Total unrecoverable damage to the fuse but the wing was undamaged....

My assessment is that this plane is unstable and must have the cg set EXACTLY right before it can be flown safely. It is also not a plane to just fly without very close attention to speed, and attitude. I don't recommend this plane for those looking for a fun relaxing flyer. Too bad as she looks great....
