Servo Tester
 

Hi you !

I need help to homebuild a servo tester to check some unlabeled second hand multiplex. Thanks for any help.

Hi you !

In time.

The tester is just to verify the torque force.

Sorry.

What aout using a digital fishing scale?

RE: Servo Tester
 

Use a one inch arm and fishing weights tied to a lead. Ounces is ounces... The one inch arm is important.

Most standard size servos are at least 48 oz-in. Torque specified. 48/16 is 3lbs.

Hi JNorton and Mglavin !!

Thank you very much for your hints. I will fit the servos which I intend to check on a 1/8" ply, use a 1" arm, use fishing pre weighted, hang up everything and run the test. That's all.

Thanks again.

IGOS R/C,

Make a pointer on the end of the 1" arm and put a degree wheel or a protractor behind the pointer. Then you can tell what type of accuracy you are getting relative to the weight.

Thanks again John.

Instead of an arm use a 1"wheel attached to the top of an arm. Then you don't have to correct for the geometry of the arm. Also a dial indicator is much better than a pointer. Just attach it to the wheel with a string. A cheap dial indicator is accurate to .001 in.
