Building your own airplane from a kit is an exciting and challenging endeavor. Whether you’re an experienced aviation enthusiast or a beginner looking to take on a project of a lifetime, having the right components is crucial to ensuring your kit plane is built safely and efficiently. With so many different options available, selecting the essential parts can be a daunting task.
In this post, we’ll cover the Top 7 Must-Have Parts for Every Kit Plane Builder. These parts are crucial to the structural integrity, safety, and overall performance of your aircraft. Not only will we dive deep into each part, but we will also explain why they are indispensable and where to find the best quality components.
1. Quality Airframe Kit
The foundation of any kit-built airplane is the airframe. This includes the fuselage, wings, and empennage (tail section). The airframe is the skeleton of your aircraft, and its quality will directly impact the overall performance and longevity of your plane.
Why it’s Important:
A high-quality airframe kit provides the precision needed for proper assembly. A solid airframe ensures your plane’s structural integrity, making it safe and reliable to fly.
- Key Considerations: Look for kits that include pre-drilled holes, which can save you a significant amount of time. It’s also important to consider materials like aluminum for strength and lightness.
- Where to Buy: There are several trusted manufacturers, like Van’s Aircraft or Sonex Aircraft, that offer high-quality airframe kits. For those looking for specialized parts, sites like Aircraft Spruce are fantastic resources for both airframe kits and individual parts.
2. Engine and Propeller Combo
The engine is the heart of your aircraft, and choosing the right one is crucial for the performance and safety of your kit plane. There are a variety of engine options available for kit planes, ranging from lightweight, low-horsepower engines to more powerful variants for long-range flying or higher speeds.
Why it’s Important:
The engine and propeller combination determines the thrust, fuel efficiency, and overall performance of your aircraft. A reliable engine will ensure that your plane is not only efficient but also safe during flight.
- Key Considerations: When selecting an engine, consider factors such as the type of flying you intend to do, the plane’s weight, and the ease of installation. You should also look into engine warranties and after-purchase support.
- Where to Buy: Rotax engines are a popular choice for kit plane builders due to their reliability and lightweight design. Lycoming and Continental engines are also commonly used, especially for larger aircraft. You can find these engines and propellers at specialized suppliers like Aircraft Spruce and Lycoming’s official site.
3. Landing Gear System
The landing gear system plays a vital role in the overall handling and safety of your kit plane. From the main wheels to the tailwheel or nose gear, the landing gear is responsible for absorbing shock during takeoff, landing, and taxiing.
Why it’s Important:
A strong and reliable landing gear system can significantly improve the stability and safety of your plane, especially during landing. It reduces the risk of nose-over incidents, vibrations, and damage to the airframe.
- Key Considerations: When selecting landing gear, make sure to choose high-quality shock-absorbing components, as they’ll enhance your plane’s performance, particularly when operating from short or rough runways.
- Where to Buy: For premium landing gear kits, AeroBuild and The Airplane Factory offer durable and affordable options. Also, Aircraft Spruce carries a wide selection of parts, including main wheels, tailwheels, and shock absorbers.
4. Avionics and Instruments
For many kit plane builders, the avionics and instrument panels are one of the most exciting aspects of building an aircraft. A well-designed avionics system provides real-time information about your plane’s performance and enhances safety through navigation, communication, and engine monitoring.
Why it’s Important:
Having up-to-date, high-quality avionics can significantly improve your flight experience. Whether you’re flying cross-country or just around the local area, you need accurate data to make decisions during flight. From GPS to altimeters, these instruments provide the vital information you need.
- Key Considerations: You should select avionics that are compatible with your aircraft’s design and the type of flying you plan on doing. Consider whether you want basic instruments or a fully-integrated glass cockpit system.
- Where to Buy: Leading avionics suppliers like Garmin, Dynon, and Avidyne offer avionics that are perfect for experimental aircraft. Aircraft Spruce also provides a full catalog of avionics, including autopilot systems, radios, and transponders.
5. Flight Controls and Cables
The flight control system consists of all the components that allow you to maneuver your aircraft, including the ailerons, rudder, and elevator. These systems are connected via cables, push rods, and linkages, which must be installed precisely to ensure smooth and responsive control.
Why it’s Important:
Precision in the flight control system is essential for safety and performance. Properly installed and maintained controls give you more responsive handling and greater stability during flight.
- Key Considerations: Make sure your flight controls are ergonomically designed for ease of use and safety. Look for high-quality cables and hardware that are resistant to wear and tear.
- Where to Buy: Wicks Aircraft Supply and Aircraft Spruce offer comprehensive kits and individual parts for building flight controls, including cables, control sticks, rudder pedals, and more.
6. Fuel System
The fuel system is another critical component of any kit plane. It is responsible for storing, regulating, and delivering fuel to the engine. A well-functioning fuel system ensures smooth engine performance and can even prevent engine failures in-flight.
Why it’s Important:
The fuel system needs to be designed to handle the specific demands of your engine. It should provide a steady fuel supply and be free of leaks, contamination, or other malfunctions. A reliable system is key to safe and efficient operation.
- Key Considerations: Be sure to select a fuel system that is compatible with your engine and meets the required standards for fuel delivery, fuel tank capacity, and fuel lines. Also, ensure that your system has filters to prevent debris from entering the engine.
- Where to Buy: For fuel systems, Airflow Systems and Aircraft Spruce offer kits that include everything you need for a complete installation, from fuel tanks to lines, valves, and filters.
7. Electrical System
The electrical system is the nervous system of your kit plane, powering everything from lights and avionics to the engine’s ignition system. Having a reliable electrical system ensures that your plane operates smoothly during day or night flights.
Why it’s Important:
Your aircraft’s electrical system powers vital components like the radio, lights, and even some aspects of engine control. A failure in the electrical system could lead to a loss of communication, navigation, or even cause engine problems.
- Key Considerations: Opt for high-quality wiring, fuses, circuit breakers, and batteries. It’s also essential to install the system with redundancy in mind, as electrical failures are one of the leading causes of in-flight emergencies.
- Where to Buy: You can find electrical kits, including wiring and battery solutions, at Aircraft Spruce and Wicks Aircraft Supply. These suppliers offer top-notch components that ensure your plane’s electrical system runs efficiently and safely.
