Got the YS110 mounted in my UCD60 last night. Haven't run the engine yet, will break in tonight and maiden tomorrow. This plane, I call Scarface, looks a little haggard from previous crashes but she flys very good. I'm hoping even better with the 110. Even with all the extra weight from repairs she's not fat. My digital scale says 8lbs 2ozs right on the money. With the havier motor I moved the battery/receiver back as far as I could reach (with out cuting a special hole etc.) and she balances right at 4 7/8" Before I was at 5 1/8" That's pretty close considering the engine weighs 6.5 ozs more than the the trusty Saito. I also moved the tank back to mostly inside the canopy area (one of the benefits of YS). This helped with the balance I'm sure. This CG is exactly where the manual recommends. I'm gonna fly there and see if I need to rebalance. I've been as far back as 5 1/2" but didn't like it there and moved to the 5 1/8" where I liked it. Liked it a lot! The 60 is like the 46 where you can balance all over the place and still have it fly great. The 46 is good anywheres from 4 1/2 to 6. I perfered about 5 3/8" or so on that baby but didn't like the 60 that far back.
Anyways, with my two new planes, Showtime and Yak...I'm stll hungry to fly the UCDs. Still some of the greatest planes out there. And greatly underrated I think. I'm betting this 110 is a riot on the UCD. And it's almost a one pound lighter than other planes with the same engine. She's gonna rocket out of a hover. Maybe even as good as my good friend gjeffers!!!!!
Thanks and have a great day.
