It's in-oz, not in/oz!

A pet peeve for servo manufacturers.

As someone who had "check your units" drilled into them for 4+ years of engineering school, it drives me nuts to see servo specs for torque in:
oz/in, kg/cm, gm/cm, etc...

It's oz-in (or in-oz, kg-cm, gm-cm, etc)!!!

Torque = force times moment arm (distance).

Like I said, just a pet peeve. It also applies to the electric motor manufacturers too.

Carry on.

Tom,

My pet peeve is :-

"Why can't servo manufacturers standardise on the diameter of the servo output shaft / number of splines"?

I hate haveing to look for a servo arm for a servo that "almost, but not quite" fits the arms I have.

Cheers,

I think we are seeing a market in it's 3rd or 4th evolution.

First Evolution
--------------------
Make all the radio gear proprietary. Sell our gear to work with our stuff.

Second Evolution
----------------------
Consumer wants to buy our "whiz-bang" servo but has a competitors transmitter/receiver. Whoops ! Some manufacturers come out with "compatible" gear as a compromise to appease consumers.

Third Evolution
-------------------
Several new makers of radio gear make their components compatible with existing manufacturer of their choice.

Fourth Evolution (future)
-------------------------------
Consumer demands that radio gear (pulse shift, channel, etc.) be compatible (or settable) and inter-changeable. We are already seeing this with channel selectable features. ANSI or ISO standards to follow ?

Well that's my take on it. Any others ?
