Perfect for hobbyists and enthusiasts looking to upgrade their remote-controlled vehicles with a reliable and efficient engine option. Part of a collection from an estate sale of an avid flyer. Was told it was only bench run. In nice conditition and turns over smoothly. I no longer fly, so only used as display. Prop and spinner not included. Box is worn. Includes paperwork, tools, stock muffler, misc. I added a new JTEC muffler for display. Look closely at photos as this is the item you will receive. Sold as is with no returns to USA only please.
