I was a bit surprised by the limited angle of movement in your video, so checked the spec. and it said 130 degrees max . This seems rather limited.

Also it is hard to believe they have 4096 resolution over that range, so what does digital 4096 mean ?

Is there any position feedback capability, it is not mentioned

Hello I-Bot ,

I just use a servo tester in the video, this kind of the tester just have around 60 degree turning angel. The video just want to show the C-mount can be fix with this servo. The other thing 4096 is the motor model number .

Hi BloodKeith

The servo does seem to offer very good torque for the price (35kgf.cm).

However, if I am not mistaken, it doesn't have position feedback, right?

This is a bit of a limitation for specific robotics projects but for other applications where feedback is not needed it seems like an interesting option.

Also, the horn is plastic, right? Is there a possibility of metal horn to support the high torques?

Hello PedroR ,

Yes , the servo have very good torque,

right ,the RS-1270 is using the PWM signal,
so it didn't have feedback.

yes , the horn is plastic ,but at the manual 1.3 Mechanical Specification,
the Horn gear spline is 25T, this means can use 25T aluminum horn to replace it. 25T is a standard with Futaba.

Hi BloodKeith, I Replaced all of Hitec servos with pro gear, leaving the controller mr-c3024, are very happy with the product, much more Powerful, Slightly Slower! But for the price paid I am satisfied! Not Being Able to say for the Predecessors! Surely these RS-1270 will be a good product if you recommended! If you want can watch my video. See next time my friend!

Hello Ostrogoto, is good.
For the coming status, I will be going to design some parts for the RS1270.
these parts can be use with the DMP RS-1270 & ProGear BL806. Then I will be make a twins robot TK05-ProGear & TK05-DMP.

I'm really curious to see the differences between the two versions TK05-ProGear & TK05-DMP. Waiting future updates, on robosavvy and yours site!

I still see a major issue with the 130 degree maximum operating angle of the RS-1270.
What is the operating angle of the ProGear ?
