If you've seen the video or pushed the "little red button" at one of our recent shows, you know how much fun it is to watch this four-in-line whine!
This kit is designed with precisely located tabs and slots, and it goes together with a bare minimum of glue. The crankshaft is actually a "kit-within-a-kit," which you put together by first assembling the Crankshaft Assembly Jig. Then you glue and assemble the crankshaft pieces together in the jig, ensuring the proper alignment and spacing of the cams. When the crankshaft is dry, sand any sharp edges and then finish assembling the rest of the engine kit.
The electric motor, momentary "on" switch, 9-volt battery connector and necessary wire are included. You have to supply a battery and two or three rubber bands to serve as the drivebelt.

Note: Typically, this Engine Model is not painted. However, if you choose to decorate it, do not paint any of the moving parts. The additional thickness of the paint will cause the moving parts to bind.
