Includes 1 review aggregated from around the web.
There are very few reviews for this servo on the web. One crawler and off-road tester who used it hard in three trucks for a couple of months reports huge torque with moderate speed, a very smooth feel across its range, and gears that remained solid. It survived repeated dunks in deep water with no ill effects, and trail-side drivers who tried it called it smooth. Speed is the only caveat: it is not lightning quick. No failures were reported.
