Gator-RC 15mm Triangle Base Angled Control Horn – Compact RC Airplane Linkage Hardware

Gator RC 15mm Triangle Base Control Horn – Angled

The most compact option in the Gator-RC triangle base control horn lineup — a 15mm angled horn on a wide 50×24mm triangle base. At just 6.2 grams, it delivers stable, precise linkage geometry for smaller RC aircraft and low-throw control surface applications where a full-size horn would be overkill.

Key features

• 15mm angled control horn — compact horn length ideal for low-throw and shorter-travel control surface setups
• Wide 50×24mm triangle base — spreads mounting load across a large footprint for greater stability than standard rectangular bases
• 2.8mm thread size — compatible with standard RC clevises and linkage hardware
• Ultra-lightweight at 6.2 grams — the lightest in the Gator-RC triangle base horn range
• Angled horn profile — reduces binding on off-axis pushrod runs for smooth, consistent control response
• Sold individually — order exactly what you need per build

Specifications

• Horn length: 15mm
• Horn thread size: 2.8mm
• Base dimensions: 50 × 24mm (triangle)
• Weight: 6.2 grams
• Horn style: Angled
• Application: Elevator, rudder, ailerons
• SKU: GRC-CH-204
• Barcode: HY007-02104
• Sold as: 1 × control horn (each)

What's Included

• 2 × triangle base plates — flat top plate and angled/curved bottom plate that sandwich the control surface for a secure, gap-free clamp mount
• 1 × aluminum pivot post (main shaft) — silver cone-shaped piece that passes through the control surface and acts as the pivot point for the linkage arm
• 1 × clevis / link arm — small black arm with hole at the end; connects to your pushrod or servo linkage
• 4 × self-tapping mounting screws — secure both base plates directly to the control surface; no pre-drilling required on most foam and balsa surfaces
• 1 × clevis pin bolt + nut — small screw and nut set that connects the clevis arm to the aluminum pivot post

Required to complete

• Pushrod linkage (size dependent on setup)
• Clevis or ball link compatible with 2.8mm thread
• Mounting screws and backplate or reinforcement (airframe dependent)

Best for

• Small RC airplanes and park flyers requiring a compact, wide-base horn
• Low-throw and shorter-travel control surface applications
• Elevator, rudder, and aileron linkages on lighter aircraft
• Sport, trainer, and light scale builds
• Builders who need the triangle base footprint in the smallest available horn length

Installation notes

• Confirm the angled horn profile suits your pushrod routing geometry before installing
• Align the horn pivot point directly with the control surface hinge line for correct throw geometry
• Use appropriate reinforcement or backplate on the control surface, especially on balsa or foam builds
• Verify full linkage travel is free and unrestricted through the complete deflection range

Why choose a triangle base control horn?

Standard rectangular base control horns concentrate mounting load on just two screw points. The triangle base spreads that load across a wider footprint with additional screw placement options — reducing the risk of pull-through on foam or balsa control surfaces and providing a more rigid, rattle-free installation over time. Even at 15mm horn length, this base design gives you a level of mounting security that a standard horn simply can't match.
