RE: Sundowner 50 with a YS110??
I'm running a YS 110 in my Sundowner 50 and it works well. Added a little tail weight to compensate...still breaking her in tho...I ran 143MPH yesterday GPS on 30% Heli. It flies nice.....no issues. I had a YS 91 in it for awhile but it was tired and needed rebuilding and decided to bite the bullet and get the new 110S engine. I actually had this plane built with electric power first and kept overamping the motors and baking out the magnets trying to go faster and faster ( Never GPS checked the speeds electric tho) ....Easier to dump in the YS91 I decided! My buddy flies his SD 50 with the new OS95 2C and he ran 139MPH!
