I flew my ucd for the first time this last weekend and thought I would share it with the group. I did as most of you, switched to 4-40 linkage and pull-pull on the rudder. I used hitec hs-545's on everthing except the rudder, hs-5945. But the big news was the YS 120FZ . I mounted a 16oz fuel tank at the cg, put a 2000mah nickel metal battery just in front of the elevator servo, and added 1 oz of lead to the tail to get the cg to 6 1/8 inch behind the leading edge.

I normally ck everything twice before take off but this time I didn't and took off with the ailerons backwards. After a few tense minutes I got it landed in one piece and reversed the ailerons to the proper direction.

This is by far the most fun plane I have ever flown. I have a 33% cap with a 3w 100, which is fun but this thing rocks. It torque rolls, waterfalls, does the best blenders i could imagine with a super tight inverted flat spin going right into a torque roll. I found that it doesn't flat spin upright well or harriers are a little shaky but I only have 9 flights on it so far. I was a little worried at first about my engine selection but it is definetly the right one. No fueling problems, easy to start and with the apc 17x6 need I say unlimited vertical acceleration. I know I need to manage the throttle, but it is like flying the cap 232 3d on the realflight sim, You can get away with almost anything. I forgot the name of the guy in the earlier post who originally installed a ys120 in his ucd. he was truly on to something and if I had known I would have bought this plane months ago. All I can say is that I'm thrilled with its performance.
