Worked great until it broke off. It says HD aka heavy-duty, it's not. When you have 555ozt servos you'd think they would make better servo horns. Do not recommend.

Works PERFECT with a self-bent throttle rod and the Mayako MX8 throttle linkage (Part MAYB0101) to rig a proper throttle set-up for the HPI Savage, just be prepared to ream out the smaller one included in the mayako kit if you want to reuse the OE Savage brake link.

Fit my Reefs SC:400 Perfect. It is just a bit long in a B6.4D. It hits one of the plastic supports, so i had to turn the steering rate down a little.

Nice servo horn, perfectly fits Serpent s411 without needing that cheap servo saver. Thanks AMain for finding this for me.

Works perfectly on the E-Revo 2.0, single servo conversion to a Raw 500.

What reviewers say

Four of five reviewers rate the Reefs RC V2 HD Servo Horn (25T, black) 5/5 and report it fitting well across several platforms, including the Reefs SC:400, Serpent S411, and E-Revo 2.0 with a single-servo conversion. One reviewer used it for a throttle linkage on an HPI Savage, noting the included smaller reamer part may need enlarging to reuse the OE brake link. One reviewer found it a little long in a B6.4D, where it contacted a plastic support, requiring a reduced steering rate. The one 1/5 review reports the horn broke after working for a period and questions its heavy-duty claim under high-torque servos. Reviews are few, so the sample is limited.

  • + Good fit on multiple platforms
  • + Works for throttle linkage conversions
  • + Fits Serpent S411 without a servo saver
  • − Breakage reported by one owner
  • − May be too long for B6.4D chassis
  • − Included smaller part may need reaming
