Futaba YS F-91 AC 4 cycle engine. W/ Super Charger & Pressurized Fuel System. This vintage engine has never seen a single drop of fuel. Has a brother I used for over 7 years. The High Performance & Reliable nature is addicting. It will Heavily overpower any. 90 size aircraft and add a whole new dimension of fun. Will move a 1.20 sized model with as much power as most of the 1.20’s out there. Bearings are smooth as glass. Stored with the piston at Top Dead Center on compression stroke to assure good valve spring life. Includes Muffler, Needle Valve, Wrenches & Check Valve. Instruction Manual is missing, but I will include a YS-120 manual which is identical. Minor cosmetic wear on box. 2,000 to 13,000 RPM. Prop Sizes: 13X12 t. Any prop that attains 9,000rpm on the ground is best in my experience. 3D use, a little higher. Weight: 26.45 ounces/ 750 grams. Priced to move fast.
