What is RC Slope Soaring

RC Slope Soaring is a type of radio-controlled aircraft hobby where pilots fly sailplanes, or other unpowered aircraft from the top of a hill or mountain and use the power of the wind to stay aloft.

Unlike traditional RC planes, RC gliders usually do not have a continuous power train that pushes them forward.

RC electric gliders, do have a motor and propeller, but in most cases, it’s only used to gain the initial altitude during the launch.

Instead, the wind and the natural landscapes create lift to keep the plane flying, allowing the pilot to enjoy a longer and more relaxed flying experience.

The goal is to fly the glider for as long as possible by performing various aerial maneuvers.

Slope Soaring as a Hobby

RC Slope Soaring is a popular hobby that attracts people of all ages who enjoy the thrill of flying, the challenge of controlling a glider, and the sense of community that comes with being a part of the RC slope soaring community.

Pilots can fly their gliders at dedicated slope soaring sites or at any location with suitable slope and wind conditions.

The hobby offers endless opportunities to learn and grow, and with the right equipment, anyone can enjoy the excitement of RC slope soaring.

Slope Soaring Spots

When choosing a location for RC slope soaring, there are several factors to consider.

Some of the most common sites include beaches, cliffs, and mountaintops. Pilots often flock to these locations because they provide consistent wind conditions and offer ample space to fly.

Slope angle and orientation

The slope angle affects the lift generated by the wind, and the orientation of the slope impacts the wind direction and turbulence.

The ideal slope angle is around 20–30 degrees, and the slope should face into the wind.

The wind is the most important factor in RC slope soaring, as it provides the lift necessary to keep the glider aloft.

The ideal wind conditions for RC slope soaring are steady and consistent, with a minimum speed of about 3–4 m/s and a maximum speed of about 10–12 mph.

Flying in high wind conditions can be dangerous, so pilots should always use caution and exercise good judgment when deciding whether or not to launch models into the air

Accessibility and safety

Finally, pilots should consider the accessibility and safety of the flying site.

Sites with easy access and clear approaches are preferred, and the area should be free of any potential hazards, such as power lines, windmills, or other structures.

A smooth and open slope is ideal, as it provides ample space for flying and minimizes the risk of crashes or other accidents.

Additionally, it’s important to check local regulations and obtain necessary permits before flying at a new site.

Best Slope Soaring Gliders

When it comes to slope soaring, choosing the right glider is crucial.

There are several factors to consider when making this decision.

Firstly, consider the type of slope soaring you are interested in doing, such as F3F competitions, aerobatics, combat, or scale flying, or anything else.

Let’s quickly check what are the differences between them.

F3F gliders

F3F gliders are high-performance racing gliders designed for competition use. They are built for speed, agility, and accuracy and are used in F3F slope racing.

Scale slope soaring gliders

Scale gliders are the ones designed to look like real aircraft. These gliders are built to scale, with realistic paint schemes and markings, and are used for sport flying and competition.

Flying wing gliders

Flying wing gliders, also known as delta wing gliders, are a type of glider that is designed with a single, large wing and no tail. They are typically built for speed and agility and are popular among advanced pilots (i.e. a Shaka Slope Glider)

Other slope and slope-converted gliders

There are many other types of gliders that can be used for slope soaring, including traditional gliders, F5K slope-converted gliders, and specialized gliders for specific disciplines like aerobatics and combat.

How to choose

Different types of slopes require different types of gliders, it is very dependent on the available landing area and surface.

Additionally, consider the size of the slope.

Larger slopes allow larger gliders, while smaller slopes are suitable for smaller gliders or the ones with low wing loading.

For example, a lot of pilots choose DLG gliders as one of the most universal airframes.

Since the modern discus launch gliders feature advanced laminar airfoils that are performing great at low and high speeds with different settings, they will be a great choice for slope soaring.

The wind conditions at the slope must also be considered.

For instance, if the wind is strong and gusty, you will need a glider that is able to fly fast and vice versa.

Lastly, consider your own skill level and experience as a slope soarer.

If you are a beginner, it is recommended that you start in low wind conditions with a glider that is easy to handle and has more stability.

As you become more experienced, you can move on to more advanced gliders.

Launching Techniques

When launching an RC slope glider, it’s important to follow the proper steps to ensure a successful launch.

First, assemble the glider turn your radio on, and complete the pre-flight routine — check the CG, move your sticks, and make sure the controls are moving as expected.

Next, position the glider at the top of the slope, facing into the wind. It’s important to make sure the glider is positioned correctly so that it will take off in the desired direction.

After ensuring the glider is positioned correctly, hold it firmly in place and run down the slope, giving the glider enough speed to take off.

The final step is to release the glider at the right moment, allowing it to soar into the air and ride the wind.

Tips for Successful Launches

  • Check the wind direction before taking off. The wind direction is crucial for the glider to launch and fly smoothly.
  • Choose the right slope. A slope with the correct angle and wind direction is essential for a successful launch.
  • Practice launching. Launching is a skill that takes practice, so don’t be discouraged if it takes a few tries to get it right. Start with a flat field with a soft grass to make mistakes heart less 😉

Common Mistakes

  • Launching too early or late. Timing is crucial, and launching too early or late can result in the glider crashing or not gaining enough altitude
  • Not facing into the wind. Make sure to face into the wind and launch directly into it to avoid the glider from losing altitude or direction
  • Holding the glider incorrectly. Ensure that you are holding the glider securely and correctly to avoid any accidents or crashes during the launch. You will need to give it a nice and firm push forward when releasing.

Slope Soaring Disciplines

Now, let’s explore some of the most popular disciplines in slope soaring. There are many more, so we’ll be touching only the top of the iceberg.

Slope Aerobatics

This discipline involves performing aerial stunts and acrobatics with slope gliders in the air. Pilots aim to perform loops, rolls, and other aerobatic moves while taking advantage of the wind currents to stay aloft.

Slope Combat

In this discipline, two pilots compete against each other in a mock dogfight. Pilots attempt to hit each other with their gliders and knock the opponent off the sky, while also performing aerobatic moves and trying to stay aloft.

The last glider flying wins the round. This discipline requires precise control and quick reflexes, as the pilots navigate their gliders through the air in an attempt to avoid being hit while trying to score hits on their opponent.

This is very exciting and fun to watch, and most importantly there is no limitation on the participants of the combat.

Scale Slope Soaring

This discipline involves building and flying scale models of real-life gliders. Pilots aim to replicate the flight characteristics and performance of their real-life counterparts as closely as possible.

Dynamic Soaring

Dynamic Soaring is a discipline of RC slope soaring that involves flying the glider back and forth across a ridge to extract energy from the wind currents and stay aloft for an extended period of time.

This is achieved by using the wind currents to gain speed and altitude, then flying downwind to maintain or even increase the speed, before turning back upwind to repeat the process.

It requires precise control and timing and an understanding of the wind currents to successfully perform dynamic soaring.

This discipline is a true test of a pilot’s skill and can provide an adrenaline-fueled flying experience.

Landing On A Slope

Landing a glider is an important aspect of slope soaring and requires proper preparation, skill, and practice.

When preparing to land your glider, it’s important to consider the following.

  • Wind conditions. Make sure you have enough wind to maintain control during landing, but not too much wind that it becomes difficult to control the glider.
  • Altitude. Keep track of your altitude and plan your landing accordingly.
  • Approach angle. Make sure you have enough speed and a good approach angle to ensure a smooth landing.

The best spots for landing on a slope are either, behind the heel, or right on top of the heel, depending on what’s available and what is the most suitable for the given weather conditions.

Behind the heel, usually, there is less wind, compared to the top of the heel and that gives you a great opportunity to drop your glider into the grass.

If the surface is all rocks and bushes, think of using airbrakes to slow down and maybe catch your glider with your hand. It will require some practice, but may safe your model on some occasions.

Why Slope Soaring is Fun

Slope soaring offers the thrill of soaring through the sky and staying aloft for long periods of time, using only the power of the wind. This experience can be exhilarating and gives a sense of freedom.

Moreover, it sometimes takes only a few pieces of foam and sticky tape to get started.

But as soon as you did, especially, if you have some mates joining you — it can be a great way to spend an evening with your clubmates.

Slope soaring has a competitive nature, with participants competing against one another in various disciplines.

This competition adds an extra layer of excitement and motivation, as well as provides an opportunity to challenge oneself and improve one’s skills.

So whether you will choose to try slope soaring along, with friends, with or without any flying experience, it may give you emotions that you couldn’t experience anywhere else.

And all these only use the pure power of nature — wind and sunshine.

Now, it’s your turn — join us on the windy side 😉
