It is best to use an atomic fission motor (85,000 rpm) for high speed.
For motors with high speed and high torque at the same time, it is best to use low speed motors.
(78,000 rpm)
Battery: If the above motors are used, it is best to use Audi 1300mA or 1800mA (for atomic fission motors) nickel-hydrogen batteries.
Tires: high-speed rubber tires (high grip)
Wheels: Closed rubber wheels (light weight) are used for high-speed rubber tires.
Chassis: speed chassis (high strength, suitable for all kinds of accessories)
Guide wheels: cyclone guide wheel (18mm), flame guide wheel (19mm), oscillating guide wheel (20mm), 18mm metal guide wheel, 20mm metal guide wheel Note: small diameter guide wheel has high stability and slow speed, while large diameter guide wheel has high speed and low stability.
High gear: 2.0: 1 high gear, 2.3: 1 high gear.
Note: calculate the gear ratio, such as 4: 1 gear (the gear of a general automobile), that is, the motor rotates four times and the wheel rotates one time, such as 2.0: 1 high-speed gear, the motor rotates two times and the wheel rotates one time. The lower the front number, the faster the speed. So we can calculate the speed of the car. The bigger the wheel, the faster the speed, the lower the stability and the smaller the wheel, and vice versa. First, calculate the diameter of the wheel, such as a wheel with a diameter of 6 cm, the blower motor rotates at 20,000 revolutions, and the gear is 4: 1. 20,000 revolutions divided by 4 equals 5,000 (6 cm equals 30,000 cm equals 300 m when the wheel rotates 5,000 times). You can run 300 meters in one minute. I came up with this myself. Don't worry, it's accurate.
Tap and phoenix tail: Super composite tap and phoenix tail.
Body protection: arrow protection
Bearing: dustproof ball bearing (reducing resistance)
Others: aluminum alloy brake device (to prevent overspeed), frog leg (to prevent rollover), platinum conductive sheet (to increase speed)
These don't have to be all-inclusive, depending on the runway type. I'm exhausted from writing so much. I am a four-wheel drive enthusiast and know something about four-wheel drive. What's bothering me in the future?
