secures to the 25T spline with an M3 bolt, the three mounting points are at 10, 15, and 20mm from center. These are etched corresponding to 2.7X, 1.7X, and 1.3X respectively. CNC machined from a solid billet of 6061-T6 aircraft aluminum, this arm is strong and light and works to promote a servo's strengths by multiplying torque at all three mounting points. Bored for M3 mounting hardware (but 4-40 fits), and as always, use threadlocker.
Fits any equipped with 25T compatible splines.
ProTip: Using torque factors is easy. Multiply the servo-rating by the torque factor etched next to the mounting location. For example, a 630oz-in servo outputs (630x1.3)=819oz-in at the outermost mounting point, 1071oz-in the middle hole, and an incredible 1575oz-in at the innermost mounting point. Since this servo arm is shorter than one-inch long, it's considered a torque multiplier arm - use care and don't fit it with hardware that's not up to the job you've been warned.
