Assembly and Operation:
Out of the Box: Ready to race once the wheels are installed and the car battery has been charged. Minimum 2 hours charge recommended.
Battery Charging: The car features a charging plug and comes with a USB charger. No disassembly required for charging. Allow battery to cool down for 30 minutes after full charge before operation. Remove charger within 30 minutes of full charge (green light) to prolong battery life. Store battery fully charged. (we use a count down timer like item 386419780550 on ours.) 
Crash Durability: Minor crashes are unlikely to cause significant damage. Personal experience with a 20MPH crash into a tree resulted in less than $20 in repairs.
Fuel Mixing: Uses a 25:1 gasoline-to-oil ratio. Fill the small compartment of the mixing jug to the 25:1 line with oil, then fill the gas compartment to the 25:1 line. We’ve had great results with Evinrude Johnson Outboard Premium 2-Stroke Engine Oil (purchased in 1-gallon jugs), which minimizes carbon buildup and avoids plug fouling. Many other brands can also be used.
Radio: This 6 channel radio essentially only uses 2 channels with this car. Trim is on the 4 adjustments under the cover on the back of the radio. Top left - steering trim. Top right - throttle & brake trim, Bottom left - control extents.
