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

Contents

MOTOR 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.

## 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 I choose an RC electric motor?

The maximum current and power is what determines how large of a prop and what size plane can be used with the 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.

## 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.

## Which electric motor is equal to what glow engine?

25 size engine equals about 500 watts, a . 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.

## 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 do the numbers mean on RC electric motors?

Generally, the first two numbers indicate the diameter of the entire can of the motor OR the diameter of the stator (the inner part of the motor) only. … Similarly, the second pair of numbers can indicate either the height of the entire motor, or only the height of the stator.

## How do I choose a RC propeller?

If choosing a three or four bladed propeller, over a two bladed one, a very general rule of thumb is to decrease the prop diameter by an inch and increase the pitch by an inch, but on some models fuselage and ground clearance issues might dictate which propeller size you can and can’t have on the model.

## Which motor is used in RC plane?

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

## What is the fastest brushless RC motor?

“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.

## Does higher KV mean faster motor?

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.

## What Kv motor do I need?

As a guide, a good KV rating for a 1:10 scale brushless buggy or 400mm race/sport balanced speedboat motor is 3300KV – a smaller or more on-road/racing-focussed model will want a higher KV rating, whereas a larger or more off-road/sport-focussed model will want a lower one.

## 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.
