About this part

This is a optional HUDY Machined Aluminum Single Arm Servo Horn, and is intended for use with KO Propo, JR, Sanwa and Airtronics servos. These CNC-machined aluminum servo horns can be used with steering servos on any 1/8 off-road car. The aluminum servo horn offers maximum steering control by eliminating the flex often associated with composite servo horns. Drilled and tapped for 3mm-linkage hardware and two holes for linkage mounting, so you can quickly and easily change the linkage angle.

Features:
  • CNC-machined aluminum servo horns
  • For 1/8 off-road cars
  • 23T fits KO Propo, JR, Sanwa, Airtronics servos
  • Laser engraving
  • Zero flex
  • Maximum steering control

Anonymouson Hudy Machined Aluminum Single Arm Servo Horn (Black) (23T)

The otner review is incorrect. It definitelly does fit the JR.We just put one on the same exact servo mentioned(9100). Its a very tight fit at first just like all the Hudy horn's are when new.

What reviewers say

Reviewers disagree on whether this 23-tooth black aluminum single-arm horn fits the JR 9100 servo. One five-star reviewer reports a snug fit that is tight when new, similar to other Hudy horns. Two verified owners rated it one star, stating it does not fit their JR 9100T servo despite being advertised for JR servos, and one of them called it poor value for the price. The reviews are few and conflicting, so fit compatibility with the JR 9100 is unresolved from this data.

  • + Snug fit reported on JR 9100 servo after break-in
  • − Does not fit JR 9100T servo for some owners
  • − Described as poor value if it does not fit
