Question, is the body of the hsr-5980SGs made of metal?
I Don’t have one but I’m pretty sure their in plastic (it’s not written in the spec sheet). The gears are made in metal and steel (and some in karbonite), I don’t think the body.
Same material as all the other servos.
No, the 5990 has the aluminum servo body.
Okay, so there is one exception to the rule. There is always an exception to a rule right, just to make sure that there is plenty of room for the marang on the face when someone says an absolute.
