Charger
You need to get batteries for the radio transmitter and the car receiver packs.
• Radio TX needs (8) eight AA batteries.
• Shaft Starter requires a 7.2Volt battery pack and charger OFNA #10195
• Car needs (4) four AA Ni-cad batteries 2000Mah or higher or (4) Alkaline., Alkaline type
batteries will work, but braking will be reduced and 30 minute life. The best for car, is to use a 5
cell hump receiver pack for increased voltage and longer life..
Recommended Option:
You may want to upgrade the car battery pack to a Ni-Cad or NiHm 5 cell type(600AE). This will
give more run time. OFNA #10212 1400NiMh Hump Pack and NiHm Battery Charger #10214
