Precision Steering Upgrade from 3RACING 3RAC-HKD26/LB

The 3RACING 2.6mm light blue aluminium double servo arm is a solid upgrade choice for Ko Propo and Sanwa users. It is engineered to improve steering precision while remaining light enough to protect the servo.

Compatibility Notes

Made to match Ko Propo and Sanwa mounting patterns, this arm offers reliable engagement and accurate travel. The dual-arm design helps deliver finer control at the wheel and on-centre feel.

Robust Yet Lightweight

Crafted from aluminium, the arm offers a good compromise of durability and minimal mass to keep servo effort down. The coloured finish is tidy and suits a range of builds.

Practical Installation Advice

Secure the 3RACING servo arm with the correct hardware and check the alignment before first use. Periodic inspections of the fastenings and spline condition will help avoid sudden play.

Will this work with my digital servo?

Yes, it can be used with digital servos that accept the same spline and bolt pattern; ensure the thickness and arm length suit your servo output and application.

How do I check for correct throw?

Set the servo to centre with your radio, fit the arm straight, then confirm endpoints and adjust sub-trim so steering travel matches expected values.

Can I replace with a single arm later?

Yes, you can swap to a single-arm horn if needed, but make sure the replacement matches spline type and provides the steering geometry you require.
