  • Thanks. Two batteries hooked in series paralled with the other two to deliver 18 volts at twice the amperage.

  • Very nice. Are those 9v batteries hooked in series or parallel?

  • Thank you. Please view my other posted engines. flyingtractors1, Ralph

  • This is a fine little engine. I've seen solenoid engines before but much cruder than this brass beauty.

  • Thanks for viewing - listening. Please see my other videos.

  • Perfect music.

  • We made a new video to show more detail and the internal system in the box, as some had asked about it. The main switch turns on the system, and each cylinder can be individually switched as indicated by the lights. The engine speed is regulared by an inline rheostat. The cylinders are set 160 degrees out of phase for optimum performance.
