DS255BLHV - 255oz-in - 0.047sec/60°
Description is under construction, eyeball the specs tab for servo details. Meanwhile, here's a gear train image showing the new all-steel gears.
Servos are not designed for people to zing-zing them back and forth using a servo arm. Doing this may damage the gear train. Reason being, the transmission is comprised of gears designed to take the force of a weak motor, multiply it many times until we get to the final drive ratio. Way it works is individual gears are designed so that a small pinion drives a larger bull. This happens in a ratio ranging from 1:3 to 1:6 through a series of combo gears to reach the final ratio, which can vary from 1:150 to over 1:400.
Thus, grabbing the servo arm and moving it back and forth isn't just driving it backwards at 3:1 or 6:1, but far worse because you're really driving the servo motor through the entire transmission's gear ratio, which for the DS255BLHV is 194:1. Means the risk is you're going to break something if you persist!
Note1; that you do it all the time with other servos is your business, but you shouldn't. Anyway, with our servos it becomes our business 'if' you ask for warranty. Reason being, once we see the teeth have been damaged (and we will), then because the servo cannot drive the gears enough to drive damage them, this means the damage came from an external force input, e.g. you grabbing the servo arm and moving it back and forth. Since we're not stupid, it's not a warranty issue.
Note2: gently moving them, e.g. returning a control surface back to center, or when folding a helicopter's main rotor blades into the holder won't damage anything.
Bottom line? If you like to zing-zing the servo back and forth using the servo arm, don't. Stop driving servos backwards, they're not meant to be driven externally! Not ours not anybody's.
