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.

What motor do I need for my RC plane?

For your first plane I recommend a motor kv between 850kv and 1500kv. The next factor to considering a motor is size. Many beginners will end up significantly over-powering their planes and doing so adds momentum in crashes. Lighter, slower planes do not break as often as fast, heavy planes.

How fast are turbine RC planes?

One of the things which attracted me to RC model planes was the speed they go – it’s really awesome from where we’re standing, on the ground….The Type Of Engine.

How much power does my RC plane need?

§ 50 to 70 watts per pound is the minimum level of power, good for park flyers and lightly loaded slow flyers. 70 to 90 watts per pound is perfect for trainers and slow-flying aircraft. 90 to 110 watts per pound is good for fast-flying scale models and some sport aerobatic aircraft.

Is a higher kV motor faster?

Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. 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.

Has a RC plane broke the sound barrier?

There have been no reports of an RC plane breaking the sound barrier to date, and this would require continued improvements and enhancements to these aircrafts and their capabilities. The combination of increased performance and ideal weather conditions could allow for it in the future.

What is the fastest RC airplane in the world?

Previous world record holder Bruce Tebo launches the DSKinetics Transonic DP glider off Parker Mountain, California, with dynamic soaring expert Spencer Lisenby at the sticks. Tebo recorded a radar-measured 548-mph world record peak speed.

How many watts does it take to fly a plane?

Power Requirement to Keep a Jet Aircraft in the Air The power required to keep a Boeing 737-300 flying at a constant altitude and speed is 7.2 × 106 watts. The rate of fuel burn necessary for the engines to produce enough power to keep the airplane flying can be calculated from the total power requirement.

How many turns is a 3800kv motor?

If you are going to race the 13.5T class than you will need to buy a 13.5T motor. The Castle 3800 is about a 10.5T 11T in terms on power to turn for the motor.

How many Watts Does a RC hacker motor 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. The chart below also lists the roughly-comparable glow and gasoline power systems for reference.

How many watts of power do you need for RC?

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. The chart below also lists the roughly-comparable glow and gasoline power systems for reference.

What makes a brushless motor an electric motor?

So no more brushes, no more commutator, no more friction between the brushes and commutator to slow the motor down. No more sparks to foul up the connection between the brushes and commutator. So, a brushless motor is really a simplified brushed motor, almost an inside out brushed motor. Or at least flipped, I guess not quite inside out.

How many amps does a 750 watt engine have?

4S (3200) 750 Watt Example: Max current 47 amps Ah = 47 / 15 = 3.2 amp/hrs mAh = Ah * 1000 = 3200 mAh
