Hitec 9380 vs 9381

It looks like the 9381 has a full metal or partial metal case? Is the 9381's holding up better than the 9380?

They are the same servo, the 9381 just has a full metal case, whereas the 9380 uses an aluminum center section with a built in heat sink and plastic case top and bottom pieces. The 9381 does not need heat sink fins cut into it as the entire case acts like a heat sink.

Is the 9380's having any failures to the plastic top? If so I should probably find the 9381's

Very seldom do they. The plastic material is a composite that resits wear really well.

Because it's the only servo on the market with a customized chipset and motor that is specific to it. This means the motor and chip are not shared with any other servo, even in the Hitec lineup. It is also the only servo engineered by Americans.

This is a flat out lie. There is no such thing as a Made in USA servo, if there were it would cost a lot more than $99.99, especially with a supposed Mil-Spec rating.

I think the ProModeler servos are assembled in the USA, but they're fairly upfront about the parts they are out-sourcing.

its ok you spend your money the way you want , I tend to do a bit of research on new products and with real world actual side by side use of these products helps make my decisions not the sales hype or price.
my promo servos are rock solid cost half as much as the 9381 and don't buzz , rattle or twitch ever and are made in florida with a few outside parts

I'm not saying don't run the product you feel comfortable with. But what I am saying is I have years of industry experience with actual lab data that backs my statements, they are factual statements. I will agree the servos may be partially assembled in the USA, but they are not made in the USA as some may believe. Sorry, the cost may be half the 9381, but the performance is absolutely half (if not less) than that of the 9381.

Has anyone ever done a servo test war? Say the 9380/1 vs the Promodeler 470?

Not specifically with the promodeler, but it has been done with other servos with higher torque ratings. The 9380 didn't move the whole time.

That sounds like an interesting YouTube video?
