Review by: John Clarke
Exceptional centering performanceI have tested a small number of my own and a friend’s servos and both the MKS servos (HV69 and HV70) performed the best in the tests with exceptional performance.
A 210mm long carbon fibre rod pointer was attached to the servo arm and deflections were read with a magnifying glass on a scale with 0.1° divisions. For the HV69 a torque load of 0.56kg.cm was applied to simulate small inflight loads when the servo is centred. At 8.2V the servo had no detectable centering error and zero gear slop. When the voltage was decreased to 4.8V the pointer drifted only 0.05°.
The MKS HV70 also had no detectable centering error but had 0.2° gear slop (very little for such a small servo).
The KST servos I tested in the same way had the following centering errors: X06 V6 ±0.18°; DS213MG V8 ±0.4°; A08 V6 ±0.1°; DS215MG V3 ±0.18°]. These small errors are probably acceptable for most model applications.
The smaller servos had a proportionally smaller torque applied.
In future I will test other MKS servos when I have a suitable model.
