Francois,

IMO there is nothing wrong with multiple switches on a control stick as long
as they are done properly. You would not want to have a 1" long switch
hanging out the side of a control stick that is very prone to accidental
activation. I fly OH-58D Kiowa Warrior helicopter in the Army and our
co-pilot cyclic stick has about 10 switches to control a wide variety of
systems.. The pilot cyclic stick has a few less, but they still more than
the maximum number on a Ray Allen stick.

I have flown briefly with the exact stick grip you are talking about. It
was very comfortable....in fact I ordered one last week for my plane
directly from the manufacturer. Go to
http://www.rayallencompany.com/index.html and you will find all the details.
I ordered the G207 and opted for switch #3 and #5 to be used in place of the
extra 2 push-button switches found on the 207. I will use the 4 small push
button switches for elevator and aileron trim. The #3 switch will be used
to operate my speed brake and the #5 switch will control my reflexor.

Included with the control are some really nice labels so you can identify
the switch functions. The stick can be mounted on a 3/4", 7/8", or 1" tube.
The real advantage of directly ordering from Ray Allen is you can specify 4
different types of switches that will be used for those 2 extra switches on
the G207.

A agree too. My intented usage is:
PTT, of course,
Aileron trim (my pitch trim is mechanical)
AutoPilot Engage/Disengage
Argus Moving map select/Info modes
Approach timer (although this is not absolutely necessary there)

It is hard to imagine that someone would put the starter and other
things on the baseball bat as stated in another post.

Here's what I am talking about, particularely the model G7:

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...
