OS two stroke .25 fx ball bearing abc motor, complete with is muffler and bolts. This engine has but ten minutes running time on it. Given to me as new and test run only. The mount holes were mis drilled by him (air head) as you can see. This does not effect the mounting of this engine. One hole is slotted on one side ( see pic) and the other side is an extra hole. This is a great running new motor if you discount the holes being drilled. I would certainly use it but I don't fly .25 size planes.has remote needle valve also . Has just as much power or more than an LA .40 or a fp .40. Take a close look because I'm only asking, 35.00 for this motor. Free shipping to in the U.S. Only. PayPal or m.o. Accepted. Ps. In case you don't know just put a washer over the slotted hole used anyway and mount the two holes on the other side no biggie, forget about the third hole.
