Hi, For sale is an OS FX Max 160 surplus to my needs. The Engine comes complete with a BMS Pitts Muffler. It runs perfectly and is in very good condition. There is one small section of fin broken at the rear that has no detrimental effect on the performance of the engine. It is visible in the photos just above the fuel line. The engine has the remote fuel adjuster. Price is reasonably firm but we can discuss. Can separate the engine and muffler $200 for the engine $100 for the Muffler or by complete as advertised. If you purchase via PayPal you will have to pay their additional fee's. Thanks for looking.
