KST 25T-5 Metal Servo Output Arm

It works. Without a bolt, it has backslash of about 0.3 mm at the end of the arm. The original plastic arm (of the same length) has a slightly smaller backslash (about 0.2 mm).

I couldn'd find long unthreaded alloy arms for my Savox wing servos. These fitted perfectly and seem very good quality.

This metal servo horn fits perfectly with my KST servos.
The quality is first rate, you may need to enlarge a hole
in the horn for linkages. but this is a small matter, I will
say the service and delivery from hyperflight is excellent.

Fit perfectly with my tgy servo, very good qualità.

The fit of the servo arm is very good, however, you then need to increase the size of the hole for the clevis. Taking in mind that the KST plastic arm has an excellent fit the clevis, I think they could have done better

It's a servo horn, but a very good one - Very strong and a perfect fit. A great companion to KST servos.

Very good quality and fit perfectly with X10 and X10-710
