Precision and longevity

Machined aluminium construction offers durability and steady handling characteristics, with 3.0mm thickness chosen to balance stiffness and weight. It reduces unwanted flex and delivers a repeatable feel during sustained use and setup changes.

Application notes

Best matched to servos using Ko Propo or Sanwa splines, this arm is suitable for many 1/10 scale applications from touring cars to light trail rigs. It works well when you need a dependable metal arm for everyday running and on-track sessions.
