I've been told that the torque rating on a servo is measured by the manufacturer on a 1 inch servo arm... a general standard in the industry...

So that a servo rated at 160 oz. has that torque at 1 inch from the center of the output gear shaft...

Thus if one would use a longer arm... maybe 1.25 inch arm, the torque at 1.25 inches is less than the stated rating of 160 oz.... and so on ... it would be less with a 1.5 inch arm .... etc. I've always know this implicitly... as longer arms cause flutter...

How can one compute the torque that is lost by using servo arms which are longer that 1 inch....????

Conversely... if the arm is shorter than 1 inch... then the torque should be more than the stated torque of the servo... How do you compute this torque...??

Thanks
