My original Lazy Ace has gone through 3 recovering jobs and some major cosmetic changes. Its now cub yellow with a Texan canopy. The engine is an inverted YS 1.20 old SC that has been rebuilt. Made a cowl, increased the vertical stab 30% and the rudder is twice as big. elevator is twice as big this was done for glider towing and float flying.

I decided to make it a trimotor and used 3 OS .61 engines. The photos show the layout. The two on the wings were mounted as close to the fuse as I could in case of an engine out there would be less yaw induced by the other engine. No side thrust all three were straight forward with only 2 degrees of down.

How did it fly? Unlimited vertical but no faster than the single YS probably due to drag. Was heavier than the single and though it handled well even with one engine out it was not an improvement over the single. It was an interesting project but I returned it to the single engine air frame and still fly it to this day. Don't be afraid to experiment its a lot of fun and very little to loose. The only thing I would recommend is to place the engines as close together as the props will allow.
