Key Applications and Projects

• Park-Flyer Aileron Upgrades: Replacing easily torn paper hinges on micro foam planes to restore crisp, immediate roll authority.

• Micro 3D Indoor Planes: Providing extreme, 45-degree+ deflection angles for the massive control surfaces on indoor flat-foam 3D acrobatic planes.

• Guillow's Balsa Conversions: The ideal scale hardware for converting small, rubber-band powered balsa glider kits into fully functional RC models.

Unlock New Capabilities (Project Evolution) The Foam Board Fighter Retrofit: Foam board airplanes are fantastic for beginners, but the standard "paper-cut tape hinge" technique eventually delaminates if exposed to morning dew or high humidity. Evolve your scratch-build! Carefully slice the moving surfaces entirely off your foam board wing. Cut tiny slots into the exposed foam core and epoxy these 12x24mm nylon hinges in place. You will instantly transform a disposable trainer into a durable, weather-resistant airframe with professional-grade control surface articulation!

Package Includes:

• 1 x Small Nylon Pinned Hinge (12mm x 24mm)

FREQUENTLY ASKED QUESTIONS (FAQ)

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

2. What are the exact dimensions of this small hinge? When completely open and flat, it measures 24mm in total length. The width of the hinge along the center pin is 12mm.

3. What aircraft size is "Small" best suited for? It is optimized for micro park-flyers, indoor 3D foamies, small foam board builds, and aircraft generally under a 900mm wingspan.

4. How many glue holes are on this specific size? Unlike the large models which have six, this small 12x24mm hinge features exactly 4 circular glue holes per leaf (8 holes total per hinge).

5. Why are there holes punched into the leaves? When liquid glue is applied, it flows through these holes and hardens. This creates physical "rivets" of glue that lock the hinge deeply inside the wing material.

6. How do I install this into my airplane? Use a sharp hobby knife to cut a thin, centered slot into both the wing and the control surface. Slide the hinge into the slots, align it, and apply thin CA glue or epoxy.

7. What type of glue should I use for balsa planes? Thin CA (Cyanoacrylate) glue is the absolute best choice for balsa, as it easily wicks into the tight wood fibers and hinge holes.

8. What type of glue should I use for foam planes? You MUST use Foam-Safe CA or a standard 5-minute Epoxy. Standard CA glue will instantly melt EPO, EPP, and EPS foams.

9. How do I stop glue from ruining the center pivot pin? Before gluing, dip a toothpick in light oil, Vaseline, or lip balm, and apply a microscopic amount directly to the metal center pin joint. This stops the CA glue from seeping in and freezing the hinge.

10. Are these hinges better than packing tape hinges? Yes. Tape hinges are prone to peeling off in humidity and become stiff in cold weather. Mechanical nylon hinges are permanent, weather-proof, and completely frictionless.

11. Will a 5g micro servo have enough power to move a surface with these hinges? Absolutely! Because these hinges pivot on a smooth metal axle, they create zero mechanical resistance, making them perfect for low-torque micro servos.

12. How many hinges do I need per control surface? For micro planes, typically 2 hinges per aileron/elevator half is sufficient. If the surface is exceptionally long, use 3.

13. Is the center metal pin removable? No, the metal pin is factory-pressed and flared into the nylon housing. It is not designed to be extracted.

14. Can I cut these hinges down to make them even smaller? Yes. If you are building a sub-micro "peanut scale" plane, you can easily snip the nylon leaves down with side-cutters without damaging the central pivot mechanism.

15. Will this hinge rust? The white nylon leaves are completely rust-proof. The central pin is metal; if you intend to fly off water or snow regularly, an occasional drop of oil on the pin is recommended.

16. Do I need to "pin" the hinge with toothpicks for security? For small, electric park-flyers (which these hinges are designed for), pinning is unnecessary. Cyanoacrylate glue "rivets" through the 4 holes provide more than enough hold.

17. How much gap should I leave between the wing and the aileron? Push the hinge into the slots until the center pin is perfectly aligned with the edge of the foam/wood. This should leave a highly aerodynamic gap of less than 1mm.

18. How do I ensure all my hinges align perfectly straight? Draw a straight center-line along the edge of your wing with a fine-tip pen before making your knife cuts. If your cuts are crooked, the hinges will bind.

19. Can I use hot glue to install these? It is heavily discouraged for this size. The slots for a 12mm hinge are very tight, and hot glue will cool and harden before you can push the hinge deep enough into the foam.

20. Does this listing include a pack of hinges or just one? This specific product listing is for one (1) individual Small Nylon Hinge. Be sure to order the correct quantity for your entire airframe (usually 10-15 per plane).
