What is the distinction between a model airplane engine and a model airplane motor?
- To begin, it is perhaps best to clarify what constitutes a distinction between model aircraft ENGINES and model airplane MOTORS. Engines are normally used to refer to the many types of internal combustion ENGINES that are accessible, whereas the term MOTOR is typically used to refer to ELECTRIC motors that are available.

What do RC prop numbers mean?
To begin, it is probably best to clarify what constitutes a distinction between model airplane ENGINES and model aircraft MOTORS. Internal combustion ENGINES are referred to as engines in most cases, but the term MOTOR is normally reserved for electric motors and other forms of ENERGY GENERATORS. Please see this page for further information about RC model airplane engines.
What size engine does my RC plane have?
The power of an electric motor is measured in watts. One horsepower is equal to 750 watts. A simple method of estimating power requirements for RC hobby applications is to use 100 watts per pound for recreational flying, 150 watts per pound for strong aerobatics, and 200 watts per pound for three-dimensional flight.
How do you read a propeller RC plane?
Scale radio-controlled aircraft propellers are often stated as diameter x pitch, with the pitch measured in inches. Propellers with diameters of 5 inches and pitches of 3 inches, for example, are referred to as 5×3 propellers. If the propeller were rotated through one revolution in a solid medium, the pitch would be the distance that the propeller would advance in one revolution.
What do the numbers on a brushless motor mean?
The configuration number informs you how many electromagnets are on the stator and how many permanent magnets are on the rotor, as well as how many electromagnets are on the stator. The number immediately before the letter N indicates the number of electromagnets present in the stator. The number preceding the P indicates the number of permanent magnets included within the rotor.
How do you read an aircraft propeller number?
The difference between the first two digits of the blade model number and the dash number at the end of the blade model number is used to calculate the diameter of the propeller. For example, the diameter of the propeller of the blade model 90DA-2 will be 88 inches in diameter (90 inches minus 2 equals 88 inches). The letter “DA” refers to the blade design.
How do I know the wattage of my RC motor?
Watts are equal to amps multiplied by volts. As an example, consider a 5200mah 4s battery. That is 5.2 amps multiplied by 14.8 volts equals 76.96 watt-hours.
How do you measure an airplane propeller?
The pitch of a propeller may be determined by laying it flat on a table and measuring 75 percent of the way from the hub to the tip. Then drawing a line across the propeller blade. The breadth of the blade at this point along the surface of the table (or the width of the blade’s shadow if there were a light on the ceiling above) is what you want to know.
How do you measure a model propeller?
The diameter of a propeller is defined as the circle that is described by the tip of a single blade during a complete revolution. It may be determined by measuring from the center of the propeller boss to the tip of one blade and then doubling the resultant distance.
What does KV mean for motors?
Kv is a unit of measure for the number of revolutions per minute (RPM) that a motor produces every volt that is applied to it. In general, the higher the voltage of a motor, the higher the RPM and the greater the power. A 9000Kv motor, for example, would be significantly quicker than a 2200Kv motor. The physical property of a motor is represented by Kv, which is similar to horsepower.
What is the Kv rating on a brushless motor?
The Kv rating of a brushless motor is defined as the ratio of the motor’s unloaded rpm to the peak voltage on the wires connecting to the coils. The motor’s unloaded rpm is measured in revolutions per minute (rpm). Having an understanding of a motor’s Kv rating can assist you in determining how quickly the motor will revolve when a specific voltage is applied to it.
How do I read my brushless motor specs?
Brushless motors are commonly classified by a four-digit number – for example, **## – where the “**” numbers represent the stator width and the “##” numbers represent the stator height, respectively. Overall, the greater the numbers and the more torque produced by a motor are proportional to its width and height.
