Hi Folks,

I am looking for 25T coupler for my servo motor to connect a long metal rod to it.
I found many couplers on Aliexpress but none of them has internal 25T. I am just afraid to destroy the teeth of my servo motor.

I found that sparkfun had a good solution but it has beed retired:



any cheap solutions ?

Will this rotate with some speed? If so you may need some kind of driveshaft joint

they are going to control angle of some parts. you can assume it is part of RC car.
