Reviews (12)

Includes 12 reviews aggregated from around the web.

Buyers rate this servo very highly: 90% of ten reviews on a helicopter retailer's listing are five stars. Owners fly it on 380, 470 and 480-class tails and call it rock solid, very fast, accurate and reliable, with one replacing an older tail servo and finding it worked perfectly. Reviewers note the construction is top shelf and it is not the cheapest.
