Just got in from the shop and saw your post. Today we cut out sticks down
for the second time.
Within the next couple of days we are going to order the foam build ups for
our seats from Oregon Aero which we will then install and cover here. Oregon
Aero needed the height above the seat pan that we wanted to end up with when
seated. Randy is 5'3" and I am 5'10" (160 lbs.) we decided that when we are
sitting in the seats and the foam is compressed that we would like our butts
up 3.5" from the seat pan.
OK, now on to the STICKS. Sitting up at the 3.5" level we played with stick
height. We are installing the Infinity Aerospace Military Stick Grips (ACS
pg. 378, purchased direct form IA).
Not having the seats completed we decided to error a bit on the long side.
After completing the cut down though the height of the stick seems right on
the money for us.
We cut the stick tubes 1 3/8 inch above the deformation created by the upper
bend. Our grip is basically 6" high and has a 1 7/16" overlap onto the top
of the stick. Therefore out grip sits on top of the stick with the base of
the grip ending just as the curvature of the stick starts.
The total height of the stick tube came out to be 18 7/8" and the distance
from the top of the tube to the 3/16 mounting hole in the bottom was 17 5/8"
leaving 1 1/4" of tube below the mounting hole. The 3/16 hole in the stick
base on the control column tube is 1 1/4 down from the top where the stick
is inserted. All dimensions for the holes are to the centers.
A 7/16" hole was drilled 2 1/4" above the mounting hole on a 45 degree angle
"forward" to allow the grip cable to exit the tube. This will put it
comfortably inside the sticks boot.
As for the stick hitting things when moved it is hard to tell at this point
if there will be problems. As you have stated there certainly is potential
for some. I am hoping that when we get to the rigging stage we will be able
to tie the desired stick movement to appropriate control surface movement.
It would seem that a "center" stick position should be able to be found that
will work out. Should know within a month. I will try and remember to report
our results.
Hope this .02 is helpful.

Subject: SR stick installation
I'm installing the sticks in my SR-2500 and seem to have a problem. First,
they seemed to be far too tall for one to sit comfortably with hand on leg in
flight. I cut one down 3.5 in. in height and this seemed much better and
still
left what seems to be adequate "stick force". The second problem is that
even with a shortened stick, with full left or right aileron and full forward
stick, the grip(s) will hit the side, angled instrument panel(s). Elevator
down
stop is set to give approx. 23 degrees nose down elevator. I do not have
wings or ailerons installed, but the aileron stops on the stick base seem to
be
set at a reasonable position. The stick hitting the panel (actually hits
several switches on the pilot's side angled panel) is not acceptable. Perhaps
bending the sitick some more would be an option. The design appears to be a
problem or perhaps I have "missed something" in my construction. Any
suggestions
would be most helpful.
