This is a 049 x 5 cylinder engine made by Hobby Aid for model airplanes and probably used.

It is a very rare item and I think it is hard to find nowadays.

There is no instruction manual.

The box is very tired.

It can be turned by hand, so it is not sticking.

If you are a collector, please acquire it at this time.

The acrylic stand shown in the photo is not included.
