Hey, howzit goin', my current club meeting led to me reciving an unidentifiable engine. It is small engine roughly the size of a cox .049 except a little wider and taller on the side it says- AMA-1.0 - On the opposite under a small silencer like a small os one, it has a symbol that looks like a box with a star in it and an M on the bottem. Throttleable and with an extended mount on tank.
