This is an optional Mugen Aluminum Throttle Servo Arm, and is intended for use with the Mugen MBX7 1/8 scale nitro buggy. This servo horn is made from high quality A7075 aluminum and provides a more direct brake feel. This horn is also very suitable for hot weather conditions.

This servo horn requires the Mugen Servo Horn Adapter Set (MUGB0430).

This product was added to our catalog on February 27, 2013.

Mugen Seiki MBX7 Aluminum Throttle Servo Arm
I bought this piece from my LHS when I got the 7R. I have yet to have any issues despite the fact there are plastic inserts. If for some reason there was such a high load going through this horn, I would rather have a $5 insert strip out rather than a $100 servo or $20 horn. This is a great piece that does improve the braking feel of the car, they are a touch more consistent through long runs.

Mugen Seiki MBX7 Aluminum Throttle Servo Arm
This absolute BS. $22 for an arm that still needs the plastic inserts that cost some $6. Issue is other metal arms will not fit the MBX7. Why cant Mugen make a full aluminum arm. Maybe they are saving for future update

Mugen Seiki MBX7 Aluminum Throttle Servo Arm
CAUTION: Even though this servo horn is aluminum, it still requires use of the plastic spline insert set (which what actually fails with the stock horns).
