Which motor is best for RC car?

What is the fastest motor for a RC car?

“The Traxxas XO-1 is the fastest RC car, full stop. The largest brushless motor on offer propels the car from 1 to 60 in 2.5 seconds. Not only is this car stylish, but it also reaches speeds over 100 miles per hour.”

What type of motor do RC cars use?

Buy a Brushless RC Car from us today! Over the past 10 years, brushless has become THE answer when anyone asked about powerful RC models.

Is a higher Kv motor better?

Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor. … A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor.

How do I choose a KV motor?

The KV value can be determined by the number of copper wire windings on the stator. Generally the higher number of winds decreases the KV of the motor, while lower number of winds increases the KV. The magnetic strength of the magnets can also affect the KV value, stronger magnets will increase KV.

What is KV RC motor?

The Kv rating (not to be confused with kilo-volt) is the RPM of the motor (k) per volt (V) with no load. … A motor with a higher Kv will have more top end speed, but not as much acceleration/torque. A motor with a lower Kv will not be as fast, but will accelerate faster and have more torque.

What is the toughest RC car?

When it comes to the building the fastest, toughest, most capable RC models, Traxxas is number-one. No other brand is as relentlessly innovative and engineering-driven to make sure every car, truck, and boat delivers maximum performance, fun, and value.

How big is a 540 motor?

Those numbers refer to the motor diameter. 540 has a diameter of 36mm.

What is a 550 motor?

A 550 motor is about a centimeter longer than a 540 motor. If otherwise constructed the same, the 540 should offer higher rpm, while the 550 will have more torque. Traxxas uses 550 motors in all its brushed models for extra wheelie-popping oomph.

What does 540 mean on a RC motor?

540/550 describes the size of the motor can. Larger numbers mean bigger can diameter. Turns and kv are related, in that the lower turn motors are higher kv. Less turns means higher rpm, with less torque.

What Kv means?

Answer: “Kv” refers to the constant velocity of a motor (not to be confused with “kV,” the abbreviation for kilovolt). It is measured by the number of revolutions per minute (rpm) that a motor turns when 1V (one volt) is applied with no load attached to that motor.

How can I make my RC car accelerate faster?

Alter the gear ratio.

  1. If you’re more focused on improving your car’s acceleration than maxing out its top speed, go with a smaller pinion and a larger spur. …
  2. Changing the size of the gears is one of the simplest and least expensive ways you get your car running faster.

How do you size a motor?

Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the newly required torque. This will help you narrow the choices down to a few select motors.

Does brushless motor size matter?

Thrust to Weight Ratio

Brushless motors come in all shapes and sizes. The general rule of thumb is to aim for 2:1 thrust to weight ratio. You aren’t going to be able to do hard core racing with it. The higher the better obviously.

How do you convert Kv to RPM?

To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt.
