Note:
Make sure wheel nuts are tight before running your car.
Use a 17MM socket wrench to tighten these nuts. Spare nuts
in blue color are OFNA #15072.
Note:
Battery life is short when using Alkaline batteries. For safety, we recommend checking
Alkaline batteries after 30 minutes. Battery strength affects radio range. If voltage drops
while running the car, you will loose control and destroy your car! This is NOT covered
under warranty.
To increase run time, upgrade receiver batteries to AA Ni-Cad or NiMH type. But, the most
important step you can make, “is to always use fully charged or fresh batteries when
running your car”.
Radio shown may vary depending on
