How Do RC Plane Flaps Work?
RC planes have been around for over a century. These small aircraft are controlled remotely by a transmitter and receiver system. The receiver communicates with the various parts of the aircraft to create precise movements. While there are many components to an RC plane, one often overlooked part that can greatly improve flight performance is the use of flaps. Flaps are movable parts on the trailing edge of the wing that can increase or decrease lift, and affect the drag of the plane. They can be especially helpful during takeoff and landing, as well as in certain flight maneuvers. Despite their usefulness, flaps are often misunderstood or misused. In this article, we will discuss how flaps work in RC planes, their impact on lift and drag, the different types of flaps, how they are controlled, and how to use them for landing. If you are new to RC planes, this article will give you a better understanding of the benefits and limitations of using flaps to improve the performance of your aircraft.
Role of flaps in lift generation
Flaps play a crucial role in lift generation and can help an RC plane achieve optimal performance. Here’s how flaps work to generate lift:
- Flaps increase the surface area of the wing and cause an increase in lift generation.
- Flaps also create a downward force that helps keep the tail of the plane down.
- When the flaps are deployed, the angle of attack increases, which can create more lift.
It’s important to understand that flaps are not always necessary to generate sufficient lift for your plane to fly. However, in certain conditions, such as a heavy payload or a short runway, flaps can be useful to create the necessary lift for takeoff and landing.
Using flaps to adjust lift and drag can also help pilots achieve the desired speed and altitude during flight. Many RC planes come with flaps built-in or have them as an optional accessory. When choosing an RC plane, consider the type of flying you want to do and the availability of flaps as an option. Some popular RC plane brands include Horizon Hobby, Tower Hobbies, and Hobby King.
How do flaps help with increasing lift?
Flaps are used on the trailing edge of the wings to increase the surface area of the wing. This increase in area helps generate more lift, allowing the aircraft to fly at slower speeds with a shorter takeoff and landing distance. Flaps also create drag, which slows down the aircraft and allows for a steeper descent angle during landing. Different types of flaps include:
- Plain flaps
- Split flaps
- Slotted flaps
- Fowler flaps
Overall, flaps are crucial for the safe and efficient operation of aircraft.

Impact of flaps on drag
When flaps are deployed, they can increase drag, which impacts the flight of the RC plane. Here are some facts about the impact of flaps on drag:
- The increase in drag can cause the plane’s speed to decrease.
- The decreased speed can also make it harder for the plane to maintain altitude.
- Pilots can compensate for increased drag by increasing airspeed or adjusting the plane’s angle of attack.
Pilots should also be aware of the potential for stall when using flaps at higher angles of attack. When flaps are deployed, the plane’s stall speed increases, which means it may stall at a higher airspeed than expected. Additionally, the increased drag can cause the plane to drop suddenly when the stall occurs.
Using flaps effectively requires careful consideration of the plane’s weight, speed, and altitude. Experienced pilots know when to use flaps to their advantage and when to rely on other techniques to adjust lift and drag.
| Advantages | Disadvantages |
|---|---|
| Increased lift | Increased drag |
| Improved maneuverability | Higher stall speeds |
| Easier takeoffs and landings | Increased complexity |
When selecting an RC plane, it’s important to consider the type of flying you plan to do and the advantages and disadvantages of using flaps.

Types of flaps
There are several types of flaps that can be installed on RC planes, each with unique advantages and disadvantages. Here are a few popular types of flaps and how they work:
Plain Flaps
- Found on many RC planes
- Increases lift by increasing surface area of the wing
- Creates drag
Split Flaps
- Similar to plain flaps, but lower surface area
- Lifts create airflow between flaps and the surface of the wing
- Introduces more drag than the plain flap
Fowler Flaps
- Designed to increase lift with minimal drag
- Flap rotates backward instead of extending downward
- Commonly used on larger RC planes
Knowing the advantages and disadvantages of each flap type can help pilots determine the best fit for their specific RC plane and style of flying.
