About this part

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 Futaba compatible servo horn.

Very good product, bought it for my Revo to be steering servo horn, second hole from the center is exactly the same, as the stock servo horn's first hole from center (stock location), the stock servo horn's outer hole is in this arm right between the third and fourth hole, so it gives even better steering response, if I use the fourth hole, than the second hole on the stock steering horn. It doesn't feel bendy and the threads are good. I tried it on one of my Traxxas plastic servos and it was quite tight fit... Hopefully it fits when I buy a metal geared servo ;)

This 25t servo horn has always been a great upgrade for a plastic horn. It gos on to servo spline and 3x6mm screw then3x14 mm for ball end/rod end. Next favorite is axial 25t servo horn. Both are great options.

I can’t find a ball joint that fits in it :( I really want a compatable one. Otherwise it’s really good it’s metal

What reviewers say

Three reviews of this black machined aluminum Futaba servo horn, averaging roughly 4.3 out of 5. Two reviewers praise it as a metal upgrade over plastic stock horns, noting it feels rigid, has good threads, and that its hole layout can improve steering response on a Revo. One reviewer reports it is a tight fit on a Traxxas plastic servo and is unsure whether it will fit a metal-geared servo. The one-star review (not verified) reports difficulty finding a compatible ball joint for the horn. Reviewers agree on build quality and metal construction, but the sample is small and fit with specific servos and ball joints is mentioned only in individual reviews.

  • + Metal construction, stronger than plastic stock horns
  • + Does not feel bendy
  • + Good threads
  • + Hole layout can improve steering response
  • − Tight fit on some plastic servos
  • − Difficult to find compatible ball joint
  • − Fit with metal-geared servos unconfirmed
