The Futaba/Robbe S3173 SVI servo is the HV replacement for the venerable S3150 wing servo, which works with normal PPM receivers. The Futaba S3173SVI is faster, more powerful, and is totally slop-free. The lack of free play, high voltage operation, and proven heritage makes this one of the best wing servos for many F3J, F3B, F3F gliders, F5J eSoarers, scale gliders and helicopters. The servo works from 5.7V to 8.4V allowing use from 5 cell NiMH batteries, 2S LiPos, and many BEC systems.

The Futaba / Robbe S3173SVI utilises the S.BUS2 interface that works perfectly with normal receivers - a Futaba receiver is NOT required. The cable is plug-in, and can also daisy-chain from one servo to the next when used in SBUS2 configuration. The new motor design is stronger and 30% faster than previous S3150 type servos. With a speed of 0.15 sec/45 ° this servo is even faster than the Futaba S3150 when used at 6V.

The servo has double mounting lugs on both sides making a servo frame superfluous. The S3173 SVI is ideal as a wing servo, even for large gliders and competition machines, as well as for small and medium sized helicopters.
