KST HS08A Wing Servo - 5.2Kg.cm 0.11s 11.0g 8mm
KST delivers once again with the KST HS08 series competition servos for F5J glider pilots and soaring enthusiasts who demand the best! The all new HS08 are almost as compact as the much loved KST X08 series and offer power and performance levels approaching that of the X10 Mini servos in an 8 mm thick case. The slim 8mm thick casing is crafted from 7075 aluminium alloy, so not only do these servos look fantastic but they are also very rigid and robust.
The HS08 series are available with wing mounting tabs (A version) or normal mounting tabs (B version), to allow convenient installations in fuselages or wings or even tail surfaces. This is the KST HS08A, the wing mount version
The KST HS08A has a hardened steel drive train and a coreless motor capable of running all the way from 3.8V to 8.4V (1S to 2S LiPo) making these WV (wide voltage range) servos will deliver the power and reliability you need.
