Dynamite's precisely Machined Aluminum Servo Arms offer maximum steering control, as well as instantaneous throttle and brake response by eliminating the flex often associated with nylon and plastic servo arms. These 1/2 arms are drilled and tapped for 3mm-linkage hardware. Sold one per package and available in four colors, they are available for JR/Airtronics/KO, Futaba and Hitec compatible versions.
This package contains one Black Hitec compatible servo horn.
I've used this particular servo on two different crawlers now for...I guess about three years now. For as thin as they are, I can't believe the abuse they can handle without bending. I've beaten the absolute crap out of these things and still haven't bent one. Holes are machined for 3mm hardware perfectly. A very high-quality horn that will take whatever you can throw at it, within reason. But I've definitely tested the limits of "within reason" with them on my crawlers.
