Reviews (90)
Includes 90 reviews aggregated from around the web.
Buyers rate this servo very highly: on a helicopter retailer's listing, 97% of roughly 86 reviews are five stars. Heli builders describe it as quiet, true-centering and easy to set up with the programming card, and use it in 380 to 420 size helicopters such as the Mini Viper. Mini-car racers say it is the one servo whose all-steel gears have not stripped on impacts. A couple of reviewers noted it is not very quiet, and one racer reports the trim can drift after hard shocks.
