CEEGEE. Sorry!!!! The Ultra Sticks are right there with the UCDs. I love them. I had the same thing with a clunk. What Raideron said. Works. Went flying today, first time since I was in the box. Fly a lot. Well, at least for me. UCD46 still not ready. Had to make DO with 60. Didn't quite tail touch but did get to within 10' of ground. Was able to hover good. Very still. That's fun. Flew 8 - 13 minute flights. Weather was almost perfect 75-80 and zero wind. Almost didn't know what to do. Anyways, had a great day. No crashes and lots of fun. Will fly again on Monday. Looking forward to it. Maybe even have 46 ready. I'm that close. Have a great Memorial Day weekend and drive safe.
Thanks,
Barry
