Gator RC 34mm Triangle Base Control Horn – Angled Nylon

The largest horn in the Gator-RC triangle base angled control horn lineup — a 34mm angled horn on a wide 24×49mm triangle base, sold as a complete ready-to-install set. Includes both base plates, aluminum pivot post, clevis arm, 4 self-tapping mounting screws, and clevis pin hardware. At 7.8 grams, it delivers the mechanical advantage and wide-footprint stability needed for mid-size to larger RC aircraft where a compact horn won't provide enough throw or leverage.

Key Features

• 34mm angled control horn — 1-5/16 inch horn length provides greater mechanical advantage and longer throw for larger control surfaces
• Wide 24×49mm triangle base — spreads mounting load across a broad footprint for greater stability than standard rectangular bases
• 2.8mm thread size — compatible with standard RC clevises and linkage hardware
• Lightweight at 7.8 grams — aluminum construction keeps weight minimal despite the larger horn size
• Angled horn profile — reduces binding on off-axis pushrod runs for smooth, consistent control response
• Complete hardware kit — both base plates, pivot post, clevis arm, 4 self-tapping screws, and clevis pin bolt and nut all included; no extra hardware needed to install
• Sandwich clamp mounting system — top and bottom base plates clamp around the control surface for a secure, rattle-free installation without requiring a separate backplate

Specifications

• Horn length: 34mm (1-5/16 inches)
• Horn thread size: 2.8mm
• Base dimensions: 24 × 49mm (triangle)
• Weight: 7.8 grams
• Horn style: Angled
• Application: Elevator, rudder, ailerons
• SKU: GRC-CH-211
• 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 or threaded rod compatible with 2.8mm thread (size dependent on setup)
• Servo with adequate torque for your control surface size and deflection requirements

Best For

• Mid-size to larger RC airplanes requiring a wide-base horn with increased mechanical advantage
• Higher-throw and longer-travel control surface applications
• Elevator, rudder, and aileron linkages on sport, aerobatic, and scale builds
• Aircraft where a standard rectangular base horn lacks the footprint stability needed for the control surface material
• Builders stepping up from the 15mm (GRC-CH-204) or 24mm (GRC-CH-206) who need the maximum horn length in the triangle base family

Installation Notes

• The two base plates sandwich the control surface — position them so the angled/curved bottom plate conforms to the underside of the surface before tightening
• The aluminum pivot post passes through both base plates and the control surface — drill a clean hole sized to the post diameter before installation
• Drive the 4 self-tapping screws evenly to clamp the base plates firmly without cracking or deforming the control surface material
• Align the pivot post directly over the control surface hinge line for correct throw geometry
• Attach the clevis arm to the pivot post using the included pin bolt and nut — apply a small amount of thread-lock to prevent vibration loosening in flight
• At 34mm, this horn produces significant mechanical leverage — verify servo torque is adequate for your control surface size and deflection requirements
• Confirm the angled horn profile suits your pushrod routing geometry before final installation
• Verify full linkage travel is free and unrestricted through the complete deflection range before flight

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. At 34mm horn length, this is the largest option in the Gator-RC triangle base lineup, offering maximum throw and mechanical advantage while retaining the wide-base mounting security the triangle design provides.
