Linkage Stopper 1.5mm D1.5mm Connector Pushrod Connectors for RC Airplane Boat

Specifications:

• Hole Diameter: 1.5mm 
• Material: High-quality plated brass/steel for corrosion resistance
• Weight: ~0.5g per unit
• Fastener: M3 or M2.5 grub screw (included)
• Compatibility: Standard Servo horns 

Key Applications & Projects

• RC Airplanes: Connecting aileron, elevator, and rudder pushrods to servos.
• Robotic Grippers: Adjusting the tension and travel of finger mechanisms.
• RC Boats: Steering rudder linkages.
• DIY Plotters: Precise movement adjustment for pen-lift mechanisms.

Project Evolution 

• Past Projects (Prerequisites): If you've mastered basic fixed-length pushrods using "Z-bends," you know how frustrating it is to get the centering exactly right.
• Feature Upgrade: This Linkage Stopper unlocks the ability to perform infinite fine-tuning without removing the horn. Just loosen the screw, slide the rod, and tighten.
• Effort/Requirements: Beginner level. Requires a small screwdriver and a standard servo.

Virtual Technician & Wiring

• Safety Warning: Ensure the grub screw is tightened firmly with a drop of non-permanent thread locker for high-vibration environments (like gas planes).
• Installation: 1. Insert the stopper post into the servo horn hole. 2. Secure the bottom nut (if applicable) or ensure the snap-fit is seated. 3. Pass the 1.5mm pushrod through the stopper hole. 4. Center your servo electronically, then tighten the grub screw onto the rod.

Frequently Asked Questions (FAQ)

1. Will a 1.2mm wire fit in this stopper?
   Yes, it will fit, though the screw will need to be tightened further.
2. Is the screw included?
   Yes, each stopper comes with a matching grub screw.
3. Can I use this for 2mm pushrods?
   No, the internal bore is strictly 1.5mm.
4. Does it fit the SG90 servo horn?
   Yes, it fits most standard micro-servo horns.
5. How do I prevent the screw from vibrating loose?
   We recommend a tiny drop of blue thread-locker.
6. What tool do I need to tighten the screw?
   Typically a small flathead or Phillips screwdriver depending on the batch.
7. Is it rust-proof?
   It is plated for corrosion resistance, suitable for humid environments.
8. Can I use this for heavy-duty 10kg servos?
   It is best suited for small to medium loads; for high-torque applications, consider larger stoppers.
9. How much weight does it add?
   It is ultra-lightweight at approximately 0.5 grams.
10. Is the bottom nut included?
    This version is designed for a friction-fit/snap-fit or includes a retainer nut based on the current revision.
11. Can it be used on underwater ROV linkages?
    It is plated, but prolonged saltwater exposure is not recommended.
12. What is the thread size of the grub screw?
    Usually M2.5 or M3.
13. Will it work with carbon fiber rods?
    Yes, as long as the rod is 1.5mm or slightly less.
14. Does it allow the rod to pivot?
    Yes, the stopper rotates freely within the servo horn hole.
15. Is this for 1/10 scale cars?
    It is commonly used for throttle/brake linkages in RC cars.
16. How do I center the linkage?
    Center the servo electronically first, then tighten the stopper.
17. Can I solder the wire to the stopper?
    It is not recommended; the screw-lock is designed for adjustability.
18. What is the total height of the stopper?
    Approximately 10-12mm.
19. Can I buy these in bulk?
    Yes, contact Probots™ support for institutional pricing.
20. Is this compatible with Arduino projects?
    Absolutely, anywhere a servo-to-linkage connection is needed.
