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.
