Analog Gauges questions

[Hobix]

So I have a few questions pertaining to fabricating analog gauges for the A10C.

 

I started making the center console last night for my pit thinking I would put a spare LCD screen behind the console for displaying the information. I tested it out and really didn't like the look or feel of it.

 

I did some research and found about a 50/50 split between using servos and stepper motors. My question is which would work better for basic functions e.g EGT TEMP, APU , Fan speed.

 

Also which kind of control interface board that will allow for the best control.

 

Thanks ahead of time.

You might find Mike's books helpful when creating a cockpit and custom analog gauges. http://www.mikesflightdeck.com/

Yea I was linked those just after I posted, wish he would sell a PDF alternative, but I guess it stops people from stealing his.. from what it looks like... intensive work.

I will add another voice to the praise for both of Mike's books. Even if it isn't in the format you want, I would say buy one anyway. It will probably make him feel better about writing his third book!

Servos are easier to get a hold of locally and have all the position sensing built in but are limited to less than 360 deg rotation usually less than about 270 deg. Stepper motors require you to do a little more electronic work like build your own "park" position sensing but can be used throughout multiple revolutions. For example a servo would be simpler for gauges like vsi or temp gauges that are limited in rotation. A stepper would be easier for gauges like an altimeter or a generic heading gauge that doesn't have a limit in its rotation.

 

Hope that helps
