RC Metal Ball Head Linkage End Connector: Red M3 Male Stud to M2 Female Socket With 300mm Linkage Rod for RC Servo

Specifications:

• Material: Stainless Steel (Rod) & High-Strength  (Ball Head housing).
• Tie rod length: 300mm
• Rod Thread: M2 (2mm Standard Metric).
• Total length of ball head: 21mm
• Ball head copper Stud screw: M3
• Adjustability: Dual-ended threaded rod allows for precise length tuning.
• Corrosion Resistance: High (Marine/Freshwater safe).

Key Applications & Projects:

• RC Marine Models: Perfect for rudder linkages in electric or gas-powered speedboats where rust is a constant threat.
• Fixed-Wing Aircraft: Provides rigid, slop-free control for ailerons and elevators on balsa or foam planes.
• Robotic Arms: Use as a precise push-pull rod for animatronics requiring adjustable throw lengths.
• Scale Crawlers: Custom steering links for 1/10 or 1/18 scale trucks.

Project Evolution:

• The Prerequisite: You’ve likely used basic music wire bent into "Z" shapes for your first builds. While cheap, they flex and loosen over time.

• The Upgrade: This Regulator unlocks Micrometer-Level Tuning. You can adjust the toe-in or rudder center point by simply twisting the rod, without unmounting the servo. It transforms your control from "toy-grade" to "hobby-grade."

• Effort Level: Intermediate. Requires basic tools (pliers/wrench) and understanding of servo geometry. No soldering required..

Virtual Technician: Assembly Tips

• Installation Tip: When installing on high-vibration models (like gas boats), apply a drop of blue thread locker to the M2 threads to prevent the ball ends from drifting during operation.
• Compatibility Check: Ensure your servo horn has a 3mm hole to accept the ball head bolt. Most standard Futaba/TowerPro horns are compatible or can be easily drilled out to 3mm.
• Safety Note: Probots™ Secure-Transit  ensures these precision threads arrive straight. Do not force the ball joint beyond its maximum angle (typically 25-30 degrees) to avoid binding the servo.

Package Includes:

• 1 X M2 Servo Linkage Rod 300mm - Stainless Steel Double-Ended Threaded Push Rod
• 1X RC Metal Ball Head Linkage End Connector: Red M3 Male Stud to M2 Female Socket

Frequently Asked Questions (FAQ)

1. What is the exact thread size of the connecting rod?
   The rod features a standard M2 (2mm) metric thread.

2. What size screw fits through the ball head?
   The ball head aperture is designed for an M3 (3mm) bolt or screw.

3. Is this linkage suitable for saltwater RC boats?
   Yes, the stainless steel construction offers excellent resistance to corrosion, though rinsing with fresh water after saltwater use is recommended.

4. Can I shorten the rod if it is too long?
   Yes, the stainless rod can be cut with a Dremel or heavy-duty wire cutter, but you must file the threads clean afterwards.

5. Does this kit come with the servo horn?
   No, the servo horn is not included; this is the linkage assembly only.

6. Will this fit a standard MG995 servo?
   Yes, provided you use a servo horn with a 3mm hole or drill the existing hole to 3mm.

7. What is the maximum angle of articulation for the ball joint?
   The ball joint typically allows for approximately 25-30 degrees of pivot in any direction.

8. Is the length adjustable once installed?
   Yes, you can rotate the rod buckle to extend or retract the length for fine-tuning trim.

9. Do I need a specific tool to adjust the length?
   Small pliers or a dedicated turnbuckle wrench are recommended for adjustments.

10. Is the ball head made of plastic or metal?
    The ball itself is metal for durability, while the housing is typically a low-friction engineered plastic or metal alloy depending on the specific batch (refer to visuals).

11. Can this be used for model airplane ailerons?
    Absolutely, it provides a rigid connection ideal for reducing flutter in control surfaces.

12. What is the total length of the assembly?
    The length is variable due to the threaded adjustment; please refer to the specific datasheet or image for min/max range.

13. Is this compatible with 1/10 scale RC cars?
    It can be used for custom steering links, but verify the M3 ball stud size matches your steering knuckles.

14. Does the ball head have slop or play?
    This is a Probots™ Lab Verified ???? part designed to minimize play for precise control inputs.

15. Can I use this with M2 ball links instead of M3?
    No, the rod is M2, but the ball heads supplied are sized for M3 mounting hardware.

16. Is thread locker required?
    We highly recommend blue (medium strength) thread locker for marine and combustion engine applications.

17. How do I mount this to a servo arm?
    Pass an M3 screw through the ball head and secure it to the servo arm with a nut (nyloc recommended).

18. Is the rod flexible or rigid?
    The rod is rigid stainless steel, designed to push and pull without flexing.

19. What is the weight of the assembly?
    The complete assembly weighs approximately 20g, negligible for most hobby-grade models.

20. Can I buy the rod and ball heads separately?
    This SKU is sold as a matched set to ensure thread compatibility.
