Key Applications and Projects

• Aileron and Flap Installation: Providing smooth, uniform roll control and drag induction across the trailing edge of your main wing.

• Elevator and Rudder Articulation: Securing the vital tail surfaces responsible for pitch and yaw control during high-stress loops and snap rolls.

• Scratch-Built Balsa Kits: The standard hardware required when building wooden aircraft from plans where custom, reliable hinge slots must be cut.

Unlock New Capabilities (Project Evolution) The Sluggish Foamie Overhaul: Does your older EPO foam airplane feel sluggish or unresponsive in the air? Over time, factory foam hinges stiffen or partially tear. Evolve your airframe! Take a hobby knife and completely sever the old foam hinges on your ailerons and elevator. Cut thin, centered slots into the foam and install these 16x29mm nylon pinned hinges using foam-safe CA glue. You will instantly notice a dramatic increase in servo speed, perfectly crisp centering, and a vastly improved roll rate!

Package Includes:

• 1 x Medium Nylon Pinned Hinge (16mm x 29mm)

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What exactly is this hinge used for? It is used to physically attach the moving control surfaces (ailerons, elevators, rudders, flaps) to the main, stationary body of a remote-controlled airplane.

2. What are the exact dimensions of this medium hinge? When opened completely flat, the hinge measures 29mm in total length. The width of the hinge along the center pin is 16mm.

3. What does "Medium Size" mean for my RC plane? "Medium" indicates it is optimally sized for standard park flyers, 1000mm to 1400mm wingspan foamies, and .15 to .40 class balsa aircraft.

4. How do I install this into my airplane? You must cut a thin, horizontal slot into the trailing edge of your wing, and a matching slot into the leading edge of your control surface. The hinge leaves slide into these slots and are permanently glued in place.

5. What is the best tool to cut the slots? A sharp #11 hobby knife works perfectly for foam and light balsa. For harder woods, a dedicated "Hinge Slotting Tool" or a specialized motorized slotter is highly recommended.

6. What type of glue should I use? For balsa wood, Thin CA (Cyanoacrylate) glue or 15-minute Epoxy is standard. If you are building a foam airplane, you MUST use Foam-Safe CA or Foam-Safe Epoxy to prevent melting the foam.

7. Why are there six holes on each side of the hinge? Those are "glue holes." When you apply the glue, it flows through the holes and hardens, creating a solid physical "rivet" of glue that locks the hinge inside the slot, preventing it from pulling out.

8. How do I prevent glue from freezing the center pin? Before installation, apply a tiny drop of light machine oil, Vaseline, or lip balm directly to the metal center pin joint. This prevents liquid CA glue from wicking into the mechanical joint and locking it solid.

9. Can I use these on foam board (FliteTest style) airplanes? Yes. While tape or hot-glue hinges are common for foam board, upgrading to these nylon hinges using epoxy provides a much stronger, professional-grade control surface.

10. How many hinges do I need per control surface? This depends on the length of the surface. A standard medium aileron usually requires 3 hinges evenly spaced. A longer flap might require 4.

11. Is the center metal pin removable? No, the pin is factory-pressed into the nylon and is not designed to be removed.

12. How do these compare to CA paper hinges? CA paper hinges are thinner and easier to install, but they are stiff and degrade over time. These pinned nylon hinges offer zero friction and generally outlast the aircraft itself.

13. Will this hinge rust if I fly off water? The nylon leaves will not rust, but the central pin is typically standard metal. If you fly float planes off water, apply a drop of protective oil to the pin occasionally.

14. Can I cut these hinges down to make them smaller? Yes. If you need a smaller hinge for a tight space (like a tiny rudder), you can carefully trim the nylon leaves down with heavy scissors or side-cutters.

15. Do I need to "pin" the hinge with toothpicks? For larger gas-powered aircraft that vibrate heavily, builders often drill a tiny hole through the wood and the buried hinge leaf, gluing a toothpick through it for extreme security. For mid-sized electric planes, glue alone is usually sufficient.

16. How much gap should I leave between the wing and the control surface? You should aim for the smallest gap possible without the wood binding. Sliding the hinge in until the pin center is perfectly aligned with the edge of the wood yields a minimal 0.5mm to 1mm gap.

17. How do I ensure all my hinges align perfectly straight? Use a straight edge and a pen to draw a continuous center line down the edge of your wing before cutting your slots. If the slots are not perfectly parallel, the hinges will bind against each other.

18. Will the nylon become brittle in freezing winter temperatures? Nylon is highly durable and retains its flexibility well in cold weather, making it vastly superior to standard rigid plastics that might snap.

19. Can I use hot glue to install these? It is not recommended. Hot glue is very thick and cools too quickly. You will likely struggle to push the hinge deep enough into the slot before the glue hardens, leaving an ugly, aerodynamically poor gap.

20. Does this listing include multiple hinges? This specific listing is for one (1) individual Medium Nylon Hinge. Depending on your build, you will need to purchase the appropriate quantity (typically 12-16 for a complete 4-channel airplane).
