Well - after 14 months of faithful service, my "Crest" UCD3D is no more. On the 3rd flight of the day, my batteries mysteriously faded out on me costing me the plane. Batteries, voltage regulator, charger, and load tester are all on their way back to the manufacturer for post-mortem.

I think I have decided to build another one. I was running an O.S. .91 Surpass w/ pump. I was pleased with the performance, but I want more power! Pulling out of a hover in summertime was impossible. I am thinking about going with a YS 1.10. Anybody have any experience with this combo?

Thanks
