Good servo, but grease the gears

Jan 02, 2020

The overall design is excellent. High quality metal gear set, ball bearings, and a case designed to fit around an extra long DC motor for high power in a small package. The gears in mine did not appear to have any grease on them though, so they may wear out prematurely if you don't add lubricant.
The range of motion is less than most servos, though that's not an issue for most uses. The servo horns are not very high quality, being rather warped (the arms point back toward the body of the servo a bit), but that doesn't really cause any problems either.
Overall very satisfied, especially for the price. I may just buy a couple more of these while they're still on sale to squirrel away for later.

Habe 4 Servos gekauft für einen schnellen Elektrosegler.
1 Servo ohne Funktion! Servo aufgeschraubt, Masse war nicht angelötet!!
Keine Funktionskontrolle??
Es sind keine HV Servos, haben aber bei 6V genügend Kraft und Schnelligkeit.
Servospiel ist mittelmäßig, bei dem Preis war es aber zu erwarten.
Deshalb werden die Servos eng eingehängt und der Servoweg voll ausgenutzt.
Wie die Haltbarkeit ist, muß sich erst noch zeigen.
Insgesamt aber für den Preis ein gutes Servo.
