Using this HOn3 2 - truck shay kit is an exciting experience. First, carefully unpack it from the original box following the included assembly paperwork. When assembling, make sure to handle the plastic and metal parts gently. Since it has an analog - DC only control, use a compatible power source. There's no lighting, so if you plan to add it later, be careful with wiring. Maintenance is simple. Keep it in a dry place to prevent rust on the metal parts. Check the motor regularly for any signs of wear.
