I purchased and installed a set of DS305CLHV on flying surfaces and a DS110CLHV on the throttle of a 35cc Yak 55M. These servos are a great value; a lot of bang for the buck, not "cheap". Running them on 2S LiFe they are fast and precise; great centering. Fairly light as well, not having a ful- CNC case (that the BLHV-series have). This helped keep the overall weight down for a lighter wing loading.
The plane flies very precise; the servos doing exactly what I command, nothing more nothing less. If you look at the construction details, it gives high confidence that these servos are designed to function in the high vibration environment of a gasser. Not too worried about a servo giving up due to mechanical failure.
It's refreshing to see a quality performance servo without the high markup.
