What size RC electric motor do I need?

Electric motor power is stated in watts. 750 watts = 1 horsepower. An easy way to estimate power needs for RC hobby applications is to use 100 watts per pound for sport flying, 150 for aggressive aerobatics, 200 watts per pound for 3D flying.

How do you size a RC plane motor?

Simply multiply the current by the battery voltage to get power. The larger the propeller’s diameter and pitch, the more current the RC electric motor will draw for a given RPM. For example, the 200Kv motor will run at 2400 RPM’s regardless of whether it has a 10×6 prop or a 11×5 prop.

How do I choose a motor and prop for my RC plane?

If you select a motor with a higher kv and a smaller propeller the speed of the thrust will be higher, and as a result your plane will fly faster. For your first plane I recommend a motor kv between 850kv and 1500kv. The next factor to considering a motor is size.

How do I choose an electric motor for my RC boat?

To select the Brushless Boat Motor best suited for a hull it is important to know the hull size and amount of cells planned to be used. Size of hull will determine the size of motor needed to push the weight. Cell count will determine the wind (Kv) of motor needed.

How do you size a brushless motor?

Typically the best place to start when sizing a brushless DC motor is matching motor size (diameter, length). Diameter ranges from 13 mm to 30 mm. Brushless DC slotted motor diameter and length are specified in inches.

How do I choose an RC motor?

Inrunners run better at higher RPM (2000-10000 RPM/V roughly) and outrunners run better at lower RPM (1000-2000 RPM/V roughly). Inrunners tend to be bigger for lower RPMs than outrunners. You can guess that the first thing you need to decide then is what speed (RPM) you want your motors to run at.

Which electric motor is equal to what glow engine?

60 size engine equals around 1200 watts and a . 90 size engine equals about 1800 watts of electrical power. When considering a 4-stroke glow engine, the conversion factor is around 1500 watts per cubic inch.

Which motor is used in RC plane?

There are two main different motor types used in model aircraft: The brushed and the brushless. containing a stator and a rotor.

What is the most powerful brushless RC motor?

Dual Motor – MGM Brushless Losi 5ive-T – Most Powerful Brushless RC in the World!

Is higher or lower KV better?

A low Kv motor has more winds of thinner wire—it will carry more volts at fewer amps, produce higher torque, and swing a bigger prop. A high Kv motor has fewer winds of thicker wire that carry more amps at fewer volts and spin a smaller prop at high revolutions.

How many turns is a 3300kV motor?

13.5

What Kv motor is faster?

Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. 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. … So turns with a lower number means a faster motor.

How do you determine the rpm of a brushless motor?

To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt. The more torque a motor needs to produce, the more current it will draw. The Kt rating designates the amount of torque a motor will produce given a current.
