Randy described the two on Facebook. The lower rating is the stall torque (as in the servo can hold its position up to that much torque). The dynamic torque is how much force would be required to stop the servo dead in its tracks if it was moving at full speed.

Quality brand servos typically use stall torque for their numbers. Cheap brands/knockoffs have been known to use the dynamic torque numbers to inflate their perceived performance. Nothing wrong with including both, as long as people understand what they mean.

One feature I dont see on many servos is the ability to put the extra cabling back into the body of the servo.

Radiopost did this, and I wish savox offered this. Its pretty damn handy feature to have when I really dont want to solder new leads on a tiny board.

We chose to offer two specs to compare side by side with other servo companies. Dynamic is "moving" ratings, compared to "static" torque and speed ratings.

We will offer gear sets in due time. Unfortunately like many things we do not have control of how these are installed. In all of the testing nobody has broken a gear.

I even ran a T190 in my 1/8 Buggy at the Nationals trying to over work, over load, and break it.....it's still in my car.

Any idea on pricing

Ty posted on another forum to expect them in the $135 range a month or so ago. I assume that is still roughly valid.

which other servo company uses both specs? i'm thinking none off the top.

so how are we to know which spec other servo companies use? mud, meet water.

ProTek offers dynamic specs on some but not all of their servos. We offer both for a reason. Right now servo specs are like "C" ratings on batteries. Some are inflated, some may not be.

We felt it was best to offer both to remove any confusion when comparing servos that may offer either.

Those speeds are insane!

How does the setup with Hotwire work? I've not seen an update to accommodate the servos, just wondering what to expect when my T120 gets here :-)

Any idea on when these will be available. Also who will be selling them?

Also, price?

This is just me spitting back info I've seen posted elsewhere, either by Tekin employees, Randy, or others:

Anywhere you can find Tekin ESCs should have them. $150 is the expected street price, so $135 after coupon codes and other promotional offers. The shorty servos are a few bucks less than the full size. Hotwire update is on the way, but getting it through the app store for Apple might take a minute for the iPhone version. Available by Christmas, if we are lucky.

150$ for a servo no better than savox? Is this because it has the Tekin name on it?

I also understand my comment will get crapped on but what makes this servo any better? Because you can plug it into a hotwire? Because it says Tekin?

It's no problem to question the utility of any item to you. It sounds like you don't need anything besides what Savox offers, so there's no reason for you to jump to something more expensive.

When you say no better than a Savox, I assume you are talking the specs listed for torque and speed? While they are probably the only way to vaguely compare servos between brands, there are so many other specifications that aren't listed. Response time, tolerance/play in the gears, case material, accuracy, and software all matter. The Tekin servos use better position sensors, are element/slash proof, and will be upgrade-able with future software updates.

Given that Tekin used solid aluminum cases, the best Tekin/Savox comparison is the $140 Savox servo. For a $10 difference, the Savox still lacks the ability to be updated with software, spin a full 360 degrees, have its center point be programmed at will, and uses a lower tolerance position sensor.

The better comparison would be Futaba's S.Bus2 servo line. They are crazy programmable (you can even plug them straight into their latest radio to program them) and have features through the roof. And most of them are $200+.

As far as the T-120 goes, it also comes with an aluminum servo horn (per the Tekin website), so there's some added value there as well.

Also, I've checked my normal online shops, and have yet to see this as a pre-order, or even listed. I'd love to hear more about a firm release date and/or general availability.
