Average Reviews:
(More customer reviews)I've used hundreds of these servos in animatronics and robot building. They're wonderful little unit subject to the limitations one would expect from a small servo.
Strengths:
-Inexpensive
-Reliable
-Nylon gears - I have found that the HS-422 deluxe servo nylon gears actually last considerably longer than Karbonite gear (and more expensive) servos when they are operated for a long period at relatively light loads. It appears that Karbonite on Karbonite wear is greater than nylon on nylon wear at these low loads over long periods.
Weaknesses
- They make standard servo noises when they move - though not the high pitched digital whine.
- Like most standard servos they cannot take a 100% duty cycle for extended periods of time without special arrangements for cooling.
- Nylon gears - Karbonite gears are stronger than Nylon and might even last longer under heavy loads. It all depends on how you're using them.A caveat - the company that I work for is thinking about selling these servos here. Its not our main business but we use so many of them and trust them so much we figured why not.
