Du-Bro - 671
The DU-BRO Super Strength Servo Arms are designed for RC hobbyists who need servo arms that are extremely strong and won’t bend or break. These arms are made from a long fiber composite material, which is much stronger than regular plastic. They are great for RC airplanes, cars, helicopters, and boats—especially in high-stress situations.
These arms also give you more control throw, especially on the longer versions. More throw means your control surfaces can move farther, which improves responsiveness and helps you fine-tune the way your model flies or drives. They work well for aerobatics, racing, and everyday use.
23T spline arms are compatible with JR, Spektrum, Sanwa, Multiplex MRC, KO & Airtronics STD size servos.
