Reviews (13)
Includes 12 reviews aggregated from around the web.
Owners are very positive. A retailer listing with 11 reviews is 10 five-star and 1 one-star, and the one-star comes with no written detail. Reviewers call it very smooth, fast, powerful and durable, and several 450-size helicopter pilots say it survives crashes that destroyed plastic-geared Align servos. A glider pilot flying two in an F3F slope racer also reports excellent results. One owner reported a gear sheared in a minor crash after about eight flights, and one asked which servo arm it takes. Overall, a well-regarded metal-case micro servo for helicopters and gliders.

Comments: Made my 450 fly awesome. I can turn the gain up twice as much as when I used the aling 410ms. Somewhat heavier than other servos, but feel faster due to the speed and torque.
