Reviews (3)
Includes 3 reviews aggregated from around the web.
There are few reviews for this servo on the web, and they are split. One on-road racer calls it an excellent, much cheaper alternative to the Sanwa PGS that works with Sanwa's high-response system, smaller and lighter, with a slightly noisy return to center. Another buyer had it drift to one side after repeated corners right out of the box and replaced it with an MKS.
