SLEC SL15 Saddle Clamps 8g (6) for RC Model Aeroplanes


Build with precision and reliability using SLEC RC Aircraft Accessories. Based in Norfolk, UK, SLEC is a cornerstone of the model aviation community, renowned for manufacturing high-quality machined balsa, hardwoods, and robust hardware. Whether you are building from a traditional plan or upgrading an ARTF model, SLEC’s "practical engineering" approach provides the essential fuel systems, control linkages, and workshop aids that British and international modelers have trusted for decades.

1. Fuel Systems & Tanks

SLEC is perhaps most famous for its Square "Maxi" Fuel Tanks, which are the industry standard for space-efficient installation in narrow fuselages.

  • Square Fuel Tanks: Available in sizes from 2oz to 14oz (and larger), these rigid tanks feature a unique shape that prevents rolling and maximizes fuel capacity in tight bays.
  • Tank Fittings & Bungs: High-quality fuel tank bung sets and specialized "Tidy Fill" fuselage-mounted plates that make refueling clean and easy.
  • Petrol/Diesel Conversions: Dedicated stopper and tubing kits to convert standard glow tanks for use with aggressive gasoline or diesel fuels.

2. Control Linkages & Hardware

SLEC hardware is designed for "zero-slop" flight control, essential for everything from trainers to high-speed sport planes.

  • Control Snakes: Heavy-duty, flexible outer and inner pushrod systems (available in various lengths) that allow for smooth control runs around internal obstructions.
  • Heavy Duty Horns & Clevises: Glass-filled nylon control horns and M2/M3 ball links that provide secure, repeatable mechanical connections.
  • Hinge Strips: Durable polypropylene hinge material that can be cut to length, offering a simpler and more robust alternative to individual pinned hinges.

3. Workshop & Field Aids

SLEC produces specialized tools that simplify the complex parts of the building process.

  • Propeller Balancers: The SL93 balancer is a workshop staple, ensuring vibration-free operation for both glow and electric power systems.
  • Building Jigs & Gauges: Specialized items like the All Square Wing Rib Building Gauge help ensure your wings are built perfectly true and warp-free.
  • Flight Boxes & Stands: High-quality wooden kit-form flight boxes and adjustable model stands that keep your aircraft secure at the field.

Hardware Selection Guide:

Product Best Used For Key Advantage
Square Maxi Tanks Narrow Fuselages Maximum volume; won't rotate in the bay.
Heavy Duty Snakes Long Pushrod Runs Low friction; eliminates "binding" in curves.
Tidy Fill System External Refuelling Eliminates the need to remove the cowl to fuel.
Saddle Clamps Undercarriage Wire Securely mounts landing gear to wooden blocks.

Builder's Pro Tip:

When using SLEC Square Tanks, the filler and breather nipples are recessed to prevent the fuel lines from kinking against the bulkhead. For the best setup, use an SLEC "T-Piece" on the vent line to connect your silencer pressure, allowing the tank to remain pressurized while making it easy to drain fuel at the end of the day without disconnecting the engine lines.
