Most accurate and reliable mini servo
« on: July 12, 2015, 06:59:33 PM »
Hi folks,

Looking for a 9g servo, but a similar weight would be acceptable as well. I need the most accurate and reliable servo available. Torque and speed do not matter. Sadly, I can't seem to find any sort of specs on accuracy, and of course it's hard to gauge reliability. I originally tried an HXT900, but it would stutter and and sometimes not move correctly. When it worked, it would work great, but I think the plastic gears must have gotten stripped.

I am now looking at Turnigy TGY-50090M since it uses all metal gears.

Using an arduino + ramps aux pins + 5v vcc for control.

Any advice would be very helpful.

Thanks!!

Servos work by measuring the angle and correcting.  How fast it corrects will affect the "accuracy".

What you want is a digital servo, (you have an analog) these react faster. You will sometimes see a dead band rating, smaller is better.

BTW, you can replace the gears in your servo as they are available.
