I just finished a Ucando 60 with a YS110 installed in it, and I am at a loss at how to balance this beast. It is very nose heavy at 5 inches back from the leading edge. I even put the battery (1100mah 4.8) right in front of the tail wheel and it was still nose heavy. I'm sure a 6volt would help, but I don't think it would be enough without adding a bunch of lead weight to the tail. I have never had a plane that was this far off of balance before. The only thing close to this was my Ucando 46, and it was the opposite with a YS63. It came out tail heavy, but I was able to balance it with a 6volt battery all the way foreward. I know that many guys put YS110's on these things, so please share with me any tricks you have figured out in balancing the plane.
