Lost of power.... but slow compared to the reasonable servos. That would need to be for some special use.

But think about it...with that much torque, you could put a longer arm on the servo, get wicked transit speed, and still have tons-o-torque.

$140 is steep, though.

It would'nt cost you 140.00
But it still is steep

Could that also be mainly for larger things like 1/5 or robots even?

Whoops. I saw the .19. When you compare that with the servos out there with speeds under .1, it is fairly slow.

And dave... to get "more speed" out of it you would want the mounting point as far in toward the center of the servo as possible. Mounting it on a longer servo horn would give even more leverage, but actually make it seem slower.

I really don't think so, but I could be wrong.

And now the more I think about it that does sound right maybe. Why have any mounting holes in towards the center of the servo then??

I doubt it.....but the AE....
