Comments: In my Traxxas Slayer they work like a Traxxas 2075 servo in 9.0Kg of tork, when my 2075 just stop to work i use a stock 2052 but the work so slow, and i put that S3050 and this 6.5kg work like a Traxxas 2075 in 9.0 tork??? To me is perfect, the negative is no waterproof. Excelent option.

October 5, 2012Application(s): Ciclic servo for Venture CP30 Heli
Comments: Been using these servos to power the ciclic of my JR VEnture CP230 Heli. Really happy with their performance and reliability.
I only give a four because I found that they had a little too much slope at the Ball Bearing after not many flights (Mild 3D).
Anyway, I bought another three today to install in a Thunder Tiger X-50Gavin
August 12, 2010Application(s): I use them on ailerons and rudder on a 35 lb elecric powered scale model. They work hard!
Comments: Good performance, at a reasonable price. Excellent resolution and centering. Futaba reliability gives peace of mind when used in this large and expensive model. A very nice general purpose digital servo.
