No, unfortunately it doesn`t. DES 448 doesn`t work
The multi teeth drive shaft (don`t know the english expression for it) is different to any other servo and the housing
doesn`t fit into the injection molded frame.
So we would have to sent a lot of bugs for tooling etc. and it`s not very famous
at europe.

Sorry for this...

Sven-

That is what we call the servo's ouput shaft.
I'm not at all bilingual, so you have zero reason to feel bad or embarrassed.
Keep up the good work, sir.

OK, I guess, "The splines on the output shaft are different than all other servos."

Or, "The output shaft is different than all other servos".

Happy New Year, Mike/All.

Thomas,
what are the clevises you are using? The body is plastic but the pin looks like metal.

The clevises you are inquiring about are MP-Jet M2 clevises. We usually see them in black instead of white. I believe Thomas can direct you as to where to get them.

Will these things handle 6.6V+?

DLG,
6V max is recommended.

Here's my initial look at the servo

Target dropped off an MKS DS6125 and a DS6125 mini for me to take a look at. I just finished playing with the DS6125mini.
Initial numbers:
Total throw available is 110 degrees over 1394us, between 776us and 2170us. That means center is actually 1473us if one wants equal 55 degrees of throw each way.

Doing the easy math, 110 degrees/1394us, equals .0789 degrees per 1us, or another way to say, it takes 12.67us to move the servo 1 degree.
Deadband as listed is .001sec (1us), but Iíll be the first to confirm it is actually less than 1us.

Why do I say this? On my Futaba txís (14mz and 8fg), the subtrim is a measurable .625us per step and the servo will respond with each .625us step. It takes 20-21 subtrim steps to move the servo 1 degree.

This gives a minimum of 2230 steps the servo can see just based on the .625us per step. Of course, itís most likely going to be higher than 2230, but I donít have anything that can output less than .625us thatís measurable to test with.

Current consumption on 6.6v is:
Idle = 2mA
First sustainable buzzing = 64mA
Note: the servo itself does not buzz unless there is force on the arm.
Peak current, moving servo gently back and forth = 446mA
Peak current, springing of TX stick = 1250mA
Peak current, stall = 1430mA

Speed is consistent, unloaded to 60 degrees at 6.6v, avg is .089seconds with low being .086 and high .093.

I am impress with the servoís resolution and precision. Though 110 degrees of total throw is what the servo is capable of, the max amount in reality is about 101 degrees depending on TX and RX combo. The reason for this is that most, if not all, tx and rx combo are not capable of transmitting/receiving less than 880us or more than 2160us (1280us total) at absolute max throws.

So incidentally, the higher the resolution a servo is the less total throw it would have given the finite TX,RX signal. The gear lash on this servo is zero. Thatís right zero. Meaning no play anywhere. That contributes to itís precision. Thatís hard to believe given the metal gears. The only thing left and time will tell, is how well the gears hold up.

After 500 complete cycles back and forth at 80 degrees total on 6.6v Life, the servos are not even warm.

Thatís it for now, will do some torque measurements as soon as I get my good scale back.

So Bob, how many of the DS6125 mini's and 6125H's you have in stock ? I was going to pick up some at the AMA convention after talking with Thomas, but both me and Sophia started feeling sick while I was there so we had to leave early.)

Looks like the mini is very close in size to a 761 with faster speed, and more torque. Durability will be key.
