How do I choose a RC electric motor and propeller for my 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.
What size electric motor do I need for my rc plane?
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.
Which type of motor is used in RC planes?
These generally make use of small brushless motors (often outrunners, but also geared inrunners) and lithium polymer batteries (Li-Po). There are also many larger 3D designs designed for two and four stroke glow engines, two stroke gas engines and large electric power systems.
How do I choose a brushless motor for my rc plane?
The higher the number, the more powerful it will be. You’ll also need to make sure to specifically check how many Amps that a motor pulls in order to find the right Electronic Speed Controller (ESC). Use an ESC that is at least 20% larger than this number.
How do I choose a KV motor?
Choosing the correct KV is very important, it’s critical for the motor operation and high motor performance which is critical for the project. There are few things that determine the top speed: Battery voltage, gear ratio (if any), wheel size ( if any) and the motor KV.
Which is the best brushless motor for RC plane?
10 Best Brushless Motor Reviews
- Traxxas Brushless Power System.
- Innovateking Brushless Motor.
- Crazepony Brushless Motor.
- Betafpv Brushless Motors.
- DYS D2830 Brushless Motor.
- Tamiya Brushless RC Motor.

Is a higher kV motor 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.
What electronics are needed for an RC plane?

- Transmitter ( Radio ) & Receiver.
- Brushless Motor.
- ESC with BEC.
- Servos – Minimum 2 required.
- LIPO Battery.
- Propeller.
How much thrust does an RC plane need?
aim for about 150W/lb on a ‘square’ prop..that should be about right. If using scale prop diameters you will need a bit more pitch than diameter. I have a simple “rule of thumb” – as follows: Measure the All-Up-Weight of the model – in pounds (lb).
What is KV rating on brushless motors?
The Kv rating of a brushless motor is the ratio of the motor’s unloaded rpm to the peak voltage on the wires connected to the coils. Knowing the Kv rating of a motor will help you determine how fast that motor will rotate when a given voltage is applied to it.
Is a higher Kv motor better?
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. If Kv is like horsepower, then Turns is the physical attribute of a motor.
What is a 540 size motor?
Any motor shorter or equal to 50 mm is called a 540 motor. A bit longer than 53mm are 550mm motors. Almost all 540 motors are a maximum of 53mm in length and so they are almost the same size.
Where can I buy a brushless motor for my RC plane?

It’s Easy! Step 4: Submit your order! Minimum order value of $100 of qualifying In Stock items (before tax & shipping).
What kind of motor is used in RC cars?
The brush type RC electric motor has been around the longest and is still used in some toy type applications. Here you can see 2 permanent magnets ( of opposite polarity i.e. north and south) mounted inside the can of an RC electric motor.
What are the power requirements of an RC airplane?
The power requirements of an RC airplane can be found below, using the total flying weight of the RC plane. 50-70 watts/ pound; Minimum level for reasonable performance. Confined to lightly loaded indoor RC airplanes and small park fliers.
How does an RC electric motor work?
The armature (stationary electromagnets) is controlled by the computer ( or in our case the ESC or Electronic Speed Control). This makes for a far more efficient RC electric motor and there are no brushes to wear out or to create friction on the rotating parts! Note that this motor is an Outrunner.
