I had a little trouble with my Mayhem with the YS110 in it. I started it a coupled of days ago, you know, just to get it ready to fly. Wouldn't run just right, so I cleaned the diaphram, and changed the glow plug. The straightened it right out. Now it runs good except still can't fly because of snow. But it's leaving fast. I don't have a 110 in the big UCD. I have a Saito 100 and it flys it very nice. I enjoy the UCDs so much. They are fun to fly and for me the Saito is such a good engine. I use a 16x4W prob on that baby and it does me just fine. I have a 110 on my Mayhem, Ultra Stick Lite and my Funtana. The US Lite and F90 I haven't flown yet since I mounted the YS. I hope to soon. I've got cabin fever bad.
Thanks,
Barry
