## What size electric motor is equivalent to a glow engine?

Many large electric motors are comparable in weight to the glow engines they are replacing. For instance a AXI 4130 motor, which is equivalent to a **.** **60 size 2 cycle engine**, weighs about 14 ounces. While the glow engine weighs about 18 ounces.

## 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.

## How do I choose the right motor 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.

## Is Electric HP the same as gas HP?

Unlike a gasoline engine, **electric** vehicles (EVs) deliver power a little differently. … The main difference is immediate power and torque. A car company may say that one of their gasoline-powered engines has 300 horsepower, but that’s actually peak horsepower.

## What is a 540 size motor?

Those numbers refer to the motor diameter. 540 has **a diameter of 36mm**. 380 has a diameter ~28mm. 280 has a diameter of 24mm. The S, L or XL after the numbers refers to the motor length.

## What size electric motor do I need?

General rule of thumb: you need **at least 2 lbs.** **of thrust for every 100 lbs.** **of fully-loaded boat weight** (people and gear included). If things like wind or current are major factors where you fish, you’ll want a little extra thrust.

## 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.
