Schübeler EDF products provide cleaner option for RC aeromodellers to fly with less noise, more efficiency

There’s a cleaner, quieter way to fly radio-controlled, high-speed jet model aircraft without a turbine-powered engine.

Electric duct fans (EDF) operate with less noise and more efficiency while still offering RC aeromodellers the potential to experience the thrill of seeing their winged replicas soar through the air. EDF planes run with multi-bladed propellers, taking in air and spinning at high speeds.

“When all components have been carefully selected and installed, the customer can expect a model aircraft with long-lasting excellent performance and reliable propulsion,” said Christian Wileschek, sales expert for RC business with Schübeler Technologies.

“But what is also important is that is quieter than a gas turbine” and doesn’t emit fumes, Wileschek added. 

Founded in 1997, Schübeler Technologies has built a global business by providing advanced fan propulsion jets and lightweight composite materials. Schübeler offers a full lineup of products including turbo fans, jets, compressors and pumps, along with an RC sports hobby division that makes electric duct fans and components for high-speed jet model airplanes. 

But RC aeromodelling is more than just a business for Wileschek and Daniel Schübeler, founder of Schübeler Technologies.

Wileschek first got interested in aeromodelling as a child. He drifted away from the hobby as he grew older before meeting Schübeler in 2010 and then going to work for him.

“It didn't take long for the fascination to get back in my head. Daniel motivated me to get active again,” Wileschek said.

Combine that passion with quality work and experience in the business, and it’s no surprise that Schübeler has built a reputation of providing comprehensive service for aeromodellers looking for a smooth EDF conversion.

“We look into every detail: the aerodynamic features of the fan itself, rotor blades, stator blades, the inlet design, the outlet design,” Schübeler said. “That’s our approach to come up with a great EDF solution. We look at the whole project for the customer.”

A technical playground

Aeromodelling covers a wide array of models including gliders, propeller planes, helicopters and jets, with each aircraft offering different challenges. But while Schübeler Technologies has made successful forays into traditional aviation, aeromodelling remains an important focus of the business. 

“The development of products for aeromodellers, especially for electrically driven jets, is something that’s still very special,” Schübeler said.

Technically, it’s a demanding task, making it especially important to produce high-quality products for hobbyists that are efficient and affordable. 

“It’s technical playground for us here in the company,” Schübeler said. “I mean this very seriously - in aeromodelling, you have no limits.”

Tailwind and possibilities

Model jets propelled by turbines fueled by kerosene soar using a lot of energy. EDF planes run on batteries that have improved over the past two decades thanks to technological developments in the industry.

EDF planes that run on batteries have other advantages too. 

“The development of safer transmitters, brushless motors and the LiPo battery technology have given the model aircraft hobby a lot of tailwind and possibilities,” Wileschek said.

Some RC aeromodellers may be looking to switch to EDF because airfields may have noise restrictions that in effect ban the use of combustion engines. Some hobbyists may be tiring of the fumes that come with using kerosene. 

Or an RC aeromodeller might be convinced to make the switch just by taking an electric RC jet for a test flight. 

“The fact that it's possible to fly jets electrically with almost turbine-like sound and convincing performance, it's just great. And for jet model builders who are more electrically oriented, building a jet replica is the highest art,” Wileschek said.

Setting the standard

Schübeler Technologies takes pride in getting the details right, making the company the ideal partner for enthusiasts seeking to switch to EDF.

Schübeler can help customers figure out expected flight speeds and flying times, controller recommendations and optimized controller settings, offering service and advice.

“And then of course battery choice and size. So that sets our approach to come up with a great EDF solution,” Schübeler said. “So we look at the whole project of the customer.”

Noted Wileschek: “We have been setting standards for many years now. So, when a customer works with Schübeler, he can be sure to get a durable and safe product with excellent performance and sound, of course.”

Below, Schübeler and Wileschek offer more information through a tutorial on picking the right EDF technology for your plane.

How do you select the right size of fan for an airframe?

Wileschek: Selecting the correct fan size is based on the size of the air intake and the outlet area of the model. Each Schübeler fan has a certain fan swept area measured in square centimeters that can be found in the model number or description. For example, “51” in a model number would denote a fan swept area of 51 square centimeters. Ideally, this size matches or comes close to the size of the intake area of the plane. If the intake of a jet model airplane is too small, and you install a fan that doesn't match the intake area of the aircraft, the fan cannot generate full power. So it's important to compare size of the intakes and fan swept area of the EDF.

What about input power, motor size, and battery size? 

Wileschek: Selection of input power, motor size and battery capacity is based on the takeoff weight of the aircraft. In addition, most customers request a specific type of battery cells. They want to use, for example, 12S, or 14S, for the CARF Joker, or for a smaller EDF jet, like the Mini Avanti, it's the 6S. We recommend the right EDF setup with controller and a battery capacity to achieve a flight time of five to seven minutes. 

Schübeler: The Schübeler EDF setup is very efficient, which generates a very high thrust - so a very high performance. We can also offer a long duration setup. We have jet-like performance with the approach and we have sufficient flight time. It's maybe not super important for a smaller jet, but it's super important for a serious jet project. You don't want to lose your jet because the battery is empty. 

Are there other practical considerations for component installation?

Wileschek: Importance should always be placed on the installation of all components. The area between the air intake and fan should be as free as possible so that the air inside the fuselage comes very clean to the fan without too much turbulence. And all components such as cables should always be fixed properly because the fan sucks in everything that's not fixed well. In addition, it's necessary to attach an inlet lip to the fan so that the air can be sucked in very clean.

So when all the new gear is installed, how will flight performance compare to a turbine-powered RC plane? 

Wileschek: The customer can expect a model aircraft with long lasting and excellent performance, and reliable propulsion with a nice turbine sound. But what is also important is it will be quieter and a more pleasant experience than a gas turbine. 

Schübeler: With turbines, it's interesting. You cannot do so much wrong, but if you do things really badly wrong, your model burns. … It's a nice technology. I like turbines. But we are focused on electrically driven jets here, of course. With turbines, it's just more effort. It's maybe also a little bit more costly, because of service, maintenance and the price of a turbine. 

How fast can you go? 

Schübeler: If you install the EDF the right way, if you have a good frame, you can go insanely fast. With a sport jet, 350 kph is no problem. But with a special speed jet project that I am testing with a colleague, we’re aiming for 500 kph. We could go faster if we decide to go with a bigger EDF system. And I think the fastest turbine jet is close to 700 kph.

If you look at the practical side of aeromodelling, you want to go to your field, unpack your plane and start flying. EDF makes that possible. You install your batteries and you’re ready to go. Once your setup works - your  flying. You need a little bit of infrastructure for loading and you need to have three sets of batteries, but you can have a really nice day of jet flying with a proper EDF model. 

Aeromodelling enthusiasts across the globe enjoy the sport, speed, and excitement of piloting their model aircraft and roaring through the sky.  It’s a passion that comes from designing, tinkering, and refining your aircraft until it’s ready for its maiden flight. Then, if you ask any Aeromodeller, once you experience the joy of flight, you’re usually hooked for life. 

That’s the case with Manfred Greve, a technical trainee at Lufthansa and electro technical engineer, who began his journey with aeromodelling when he was just a toddler and now has over 50 years’ experience.  In this episode of the Software and Technology Podcast, Manfred shares his knowledge from years of flying, aeromodelling, and why he chose to convert his model aircraft to electric ducted fan (EDF) technology. Listen to the podcast in the player or read the summary below.


Like father, like son

To understand Manfred Greve’s enthusiasm for electric ducted fan (EDF) technology, you have to know a little bit about his childhood.

Greve’s father began aeromodelling in the 1950s and his love for flying model airplanes naturally transferred to young Manfred. His fascination started as a toddler, when little Manfred received a small wooden glider for Christmas and was soon flying it all around his home. He was a model airplane pilot at heart, and that love for building and flying only grew with age.

After school, Greve would race down to his cellar where his father’s planes waited. He would spend hours on a never-ending quest to improve his father’s planes. Faster. A smoother flight. A longer flight. Nicer looking. Sometimes the results were not to his dad’s liking.

“When my dad came home from work in those days, he would sometimes go crazy because I did something I shouldn't have done, but it was always interesting to face technical issues and adjust the plane into a better shape,” Greve said. “I tried a lot of different things with model airplanes, some of them unique. It’s trial and error, and trial and error, and then you suddenly get the improvement you wanted to have… it brings your heartbeat up.”

Little has changed for the aeromodel pilot of over 50 years. Greve has spent a lifetime tinkering with the designs of model airplanes, chasing that feeling he gets when that certain adjustment results in better performance. This passion has served him during decades of model plane-flying competitions, first as a 6-year-old with a glider and gradually progressing to regional and international events as an adult.

A Dragon Spitting Fire

So, when Manfred was in a flying field with two other pilots around 10 years ago and saw firsthand how a plane fitted with EDF technology compared to a plane with a gas engine, he knew then and there EDF technology was the way to go.

Right away, he noticed that the gas engine took up to three seconds to respond to the pilot’s controls, while the plane fitted with EDF technology responded with virtually no lag time. He uses the analogy of driving a car to explain the difference between the two.

“Let's say you're driving eighty miles an hour. In three seconds, you cover a lot of space. It is very important for you as a driver in a car that the brakes or the accelerator react when you want them to,” Greve said. “And this is the biggest difference with gas engines and EDF. For an aeromodel pilot flying competitions, it's very important to have the feeling on the stick. You do something on your control stick, then you really like to have the accurate reaction on the plane.”

Since that experience, Greve has made a focus of converting gas-engine planes into planes fitted with EDF. He partnered early on with Schübeler Technologies to build EDF planes during a time when smooth-running EDF planes weren’t widely available on the market.

The journey with Schübeler has not been unlike those childhood days in the basement, building bigger and bigger EDF planes that will compete with gas engine planes, but with lower noise and more consistency. Through a constant process of improvement, Schübeler Technologies, Greve said, has been able to duplicate the desired sound from a gas-engine plane, but without the off-putting volume. Schübeler EDF-converted planes sound like jet planes – like a dragon spitting fire – as Greve puts it, only at lower decibels.

“Only the Schübeler EDF gives you this sound because of its blade system.”

The Schübeler Difference

Greve points to his work with Schübeler on two planes in particular – the L-39 and the Avanti XS.

The L-39, a large, 25-kilogram model, was the first big Schübeler plane converted to an EDF system. Greve and Schübeler tried a lot of different versions to see how EDF would work with such a big plane. They started with a smaller amount of thrust – 16 kilograms – and gradually built up, building different motors and other components inside the EDF system until they had 25 kilos of thrust.

Greve and Schübeler run through an entire measurement system when converting a plane to EDF. They look at RPMs, voltage, air speed, temperature and other factors. The result, in the case of the EDF-converted L-39, is a plane that flies as well as the original, and sounds like the original, too, only not as loud.

With the successful conversion of the L-39, Greve and Schübeler turned their attention to another plane, one that perhaps would pose an even bigger challenge to convert to EDF technology. The Avanti XS is designed for aerobatics, which means the EDF system constructed would have to produce a large amount of thrust.

However, by making small changes to its EDF system, like cutting out some existing rips and building a better intake, they were able to create the thrust necessary for the EDF-converted Avanti XS to perform the aerobatics for which it’s known.

“In the aerobatic plane, you need more thrust because you want to go straight up and in every situation you want to have this good feeling on the sticks. You need thrust, thrust, thrust. That's it,” Greve said. “Our RPM window is much lower. It is up to 20,000 or something. So it is not necessary to bring these high RPMs up and down. And this gives you the short reacting time on the stick.”

While sound is critical to Schübeler’s customers, consistency and efficiency are two other factors that separate Schübeler EDF conversions from their gas-engine counterparts, Greve said. With Schübeler EDF-converted planes, enthusiasts don’t have to worry about government regulations regarding noise or oil disposal.

“Electric flying is much nicer for a pilot because a gas engine or a gas turbine is always a little bit like a racehorse,” he said. “It has a good day or maybe it has a bad day.”

Schübeler makes the jump to EDF technology easy, Greve said. Whether you are looking for a plane that flies like a rocket, or one that simply flies smoothly, Schübeler can design a system that fits you. And if its advice you seek, the Schübeler team is comprised of enthusiasts just like you who love to share their vast experience, either in person or through the company’s website.

“Every single question that comes up, we are able to answer,” Greve said. “We are able to help by building something special for the customer. We are always able to help. You will always get a proper answer, what you need and where to get it, and then you put it in your plane and you should be happy with it.”
