For Sale : Vintage HP 49 Vt Rotary Valve 4 stroke RC airplane engine . I bought this a while ago and planned to use it on a project I was going to build . The project did not materialize , so I have no need for the engine now . The engine did not come with a muffler , but I did have a Saito that fits perfect. Prop and prop nut included . New glow plug has been ordered (KB 7311 long) swings a 11-6 to 12-6 prop . These engines are made by Mecoa in Austria , run very quiet . Buyer pays shipping cost . Feel free to ask any questions .
