AONTOKY Pushrod And Lock-On Horns Kit
The AONTOKY kit combines steel pushrods with nylon lock-on control horns designed for precise alignment and secure installation. The pushrod features a 0.047″ diameter with a 10.24″ length, making it suitable for micro servos and a range of compact RC aircraft projects. The nylon horns include four holes, enabling multiple horn positions for different control surface configurations. These components are intended to simplify setup and reduce the need for glue during installation, while providing dependable performance under flight loads.
HobbyPark Nylon Horns & Pushrods Combo
This 20-piece HobbyPark set emphasizes easy, glue-free installation with lock-on nylon control horns that have four holes for secure mounting. The package includes 20 nylon horns, 20 Clevis connectors, multiple linkage stoppers, and 20 steel pushrods, all designed to fit RC airplanes, scale models, indoor flyers, and small electric park flyers. The backplate design locks over serrations to prevent horn slippage, ensuring stable servo-to-control surface linkage during flight.
Adjustable Pushrod Connectors & Nylon Horns
This kit emphasizes flexibility, providing 21×10 mm nylon horns with four holes and an adjustable pushrod connector kit with 1.3 mm stoppers. The connectors accommodate pushrods in the 1.0–1.3 mm range, enabling precise control surface geometry adjustments. The pushrods are described as easy to bend to fit the required angles, making them suitable for micro servos and various DIY projects, including RC planes and boats. This option is ideal for users seeking on-the-fly tuning without compromising strength.
Hobbypark Steel Z Push/Pull Rods (10-Pack)
These HobbyPark Z push/pull rods are built from steel with a 1.2 mm diameter and 180 mm length, offered in a 10-pack suitable for multiple control surfaces across a single aircraft or several models. The steel construction provides durability for high-stress links, while the straight-to-Z design supports easy bending and alignment. They are a practical choice for users who require robust linkage rods that can withstand repeated movements without significant wear.
uxcell 450mm Steel Z Push/Pull Rods
The uxcell set features stainless steel Z push/pull rods with a 1.2 mm diameter and a long 450 mm length for versatile applications in RC boats, cars, helicopters, and airplanes. The Z-shaped head on one end and a straight other end provide flexible mounting options and straightforward bending to fit complex control surface geometries. These rods are designed to work well with various micro servos and DIY projects, offering a balance of stiffness and adjustability for precise control linkages.
Buying Guide: Key Purchase Considerations For RC Pushrods
- Material and Durability: Steel pushrods offer high stiffness and long life under repeated servo movement, while nylon horns and connectors reduce weight and simplify installation. For high-stress control surfaces or larger models, steel components are typically preferred; for small indoor planes or lightweight builds, nylon is often suitable.
- Diameter and Length: Pushrod diameter and length determine load capacity and reach. Common sizes include 0.047″ and 1.2 mm diameters, with lengths ranging from 180 mm to 450 mm. Choose dimensions that match your servo size, control horn spacing, and available space on the airframe.
- Locking Mechanisms: Lock-on nylon horns with serrated backplates or multiple hole configurations improve security and reduce the risk of horn slippage in flight. Ensure the lock mechanism is compatible with your control surfaces (ailerons, elevators, rudders).
- Adjustability: Adjustable pushrod connectors and stoppers enable fine-tuning of control throw, travel, and trim. This is essential for achieving precise handling and stable flight characteristics.
- Compatibility: Confirm compatibility with your RC model’s servo type, horn pattern, and attachment points. Indoor and small electric park flyers may benefit from lighter, shorter components, while larger models demand sturdier, longer rods.
- Installation Ease: Look for kits that minimize glueing and provide clear assembly steps. Backplates that lock over horn serrations can simplify alignment and reduce maintenance during field adjustments.
- Availability and Spares: A broad selection of pushrods, horns, and connectors ensures you can source replacements quickly if a part wears or breaks during a build or field repair.
When selecting pushrods for RC planes, consider the overall linkage system: control horns, connectors, and pushrods should work in concert to deliver predictable throw and reliable servo response. For hobbyists building multiple small aircraft or performing frequent maintenance, modular sets with interchangeable parts offer the most flexibility and value. For pilots prioritizing durability and long-term use on bigger airframes, steel components paired with locking nylon horns can provide robust performance with straightforward field adjustment options.
