Has anyone got an appreciation of the RAC (formerly Menzimer Aircraft
Corporation) stick grips? I am particularely interested in the multiple
switch model.

Don't know which one that is, but there's a lot of very bad human
factors that goes into stick grips with lots of switches.

Attributes of things you want on the switch:
* You use 'em a lot
* You need 'em in a hurry
* If you push 'em by mistake, no big deal

A disadvantage of things on the stick is that they're usually not
labeled, and if they are, you may have to remove your hand to [try to]
read the label.

Best examples of things that may belong on the stick are electric trim
and push to talk.

Things you should *not* have on the stick are starter, flaps, and cowl
flaps. Some folks do that, but...
