Where there is a dash (-) indicates missing data from the company specs sheet. Knowing what the specs mean is the only way to make well-informed decisions. The point is to get used to reading the product descriptions. Whether you use these or not doesn’t matter. The products below are some of the popular choices used by enthusiasts for various models. This straightforward guide is for novice heli fans looking for new or replacement RC motors. The maker’s specs should now make a lot more sense. The second half of this page looks at some real motors for RC helicopters of various types and sizes. The flight battery must supply the burst AMPS the motor’s rated for.BAD: Motor AMP draw is equal to or larger than the ESC capacity.GOOD: ESC AMP capacity 20+ percent or higher than the motor’s draw.Opt for an ESC current value that’s 20% or more than the motor’s current value. Check the motor’s amps to find the correct Electronic Speed Controller or ESC. Watt ratings are found on the motor’s spec sheet. The watts of an RC motor determine its power. The “watt” is a unit of power named after the inventor of steam engines, James Watt.

#5 How to Determine Motor PowerĪMPS (current) x VOLTS = WATTS (the motor’s equivalent to horsepower) Point to note: RC engine manufacturers tend to be overly optimistic with KV numbers.

Higher KV: Spins faster but has less strength.

Lower KV: Spins slower but provides more torque.

There are 2 things to consider with the KV numbers: This number means the motor spins at 1000 RPM per 1 volt. It tells us the relationship that links volts to revolutions per minute (RPM). The way to identify the speed that an RC motor turns is to look at the KV number. The quicker the motor, the faster the potential is for your RC heli or other aircraft. The first number “22” is the motor’s diameter, and the second “04” is its height. The number may look something like this, 2204 or 22-04, but it’s the same reading. #3 How to Determine Motor SizeĪ simple height/width number tells us the size of RC motors and is usually printed on the casing. Inrunners are often-though not always-the preferred option for RC helis. The gearbox shafts bend easily, and the gears eventually get stripped. However, the extra internal parts also mean there’s more to go wrong. Inrunner motors turn the fastest out of the two, which makes them more efficient. High Revolutions per minute (RPM), low torque The best option depends on flying styles and expectations.

Outrunners: The entire outer hub spins around the center.

Inrunners: The shaft rotates on the inside of the motor’s hub.

Inrunner and outrunner motors are not the same, so which is best? Let’s compare: So, the advantages of brushless motors are less maintenance, fewer problems, and cost savings in the long term. These motors are quieter as they don’t suffer the same electromagnetic and electrical noise.

They have better power efficiency as well. These things combined make them an attractive choice for novice RC pilots and those who like to tinker.īrushless motors may cost more, but they last longer because there are no brushes to wear out. Another advantage is that they’re highly configurable. They’re also quite reliable and cost much less than the brushless alternatives. Brushed motors are simple in design with their two-wire control. The older brushed technology is inferior to brushless in many ways, but it still has a place. Let’s get started and break these things down into plain English. Here are the areas covered in this introduction to RC motors: You can go on to learn more once you have these basics down. The sections below look at the ones that matter most. You’ll have a better grasp of those numbers and abbreviations by the end of this short intro. That’s because the product descriptions are technical rather than descriptive. See all of the specs here.Ĭhoosing RC motors for helicopters or other aircraft can be daunting for the novice.
