Well it finally happened. All the talk about weak landing gear wood finally caught up to me. Letting an expert pattern flyer try out the UCD bragging that it flew like a pattern plane on steroids, he was putting it through its paces doing his pattern routine in about a fifth of the space he normally flys and then upping the rates to roll, hover, etc. (he didn't want to land as he was havin too much fun) brought it in to land and commented how slow it got and put it down like a feather. The idle was up a bit so he zig zagged it to slow it down when it happened, the gear came off. He said in a suprise what the h---l and then the jeers of fellow pilots "he hit the retrack switch." Was supprised to see two 1/8th inch dowells on the front of the block with a small triangle stock on the trailing edge top and glue? not much if any. It came out clean (except for the dowells on the front). I added a large hardwood triangle stock where the short piece was and reglued it back in. I dowelled the block of wood/triangle stock in 5 places through the leading edge wing former. I think this will work as I had 25 flights on the plane before this. One other mod I would recommend to anyone putting the UCD together out of the box is to not use the stock elevator servo cut outs without checking how the servo arm hole and elevator horn height line up. I like my control rods (used 4-40 bb rocket city connectors w/ 4-40 rods) to be in line; not at an angle. The plane flies better and the servos are not strained as much. I also went to pull/pull on the rudder putting the servo in the fuse under the trailing edge of the wing. CG is 6" and still nose heavy. My $.02.
