My friend Gifford (Giff) Gillingham is a prolific airplane builder. He
has designed and welded these pedals and stick for me.
I'm making this a single place so I placed the pedals far to the side to allow more
room to strech out and possibly for a radio stack in between the legs. The header
tank will prevent the radios from going directly into the panel
The first stick I built was very much but not exactly to plans. When I went fore and
aft on the stick it seemed I was streching the aileron cables. When I showed Giff
the problem I was having he came up with this design. It is very simular to a dual
stick design but with a single center stick. With this design the aileron cables are
not biased. I tried to  put the elevator lever below the pivot tube but with the pivot
tube being so low I could not get the required elevator travel without an additional
lever between the spars to effectively increase the travel of the stick. So we
designed a bent control tube to go from the top of the stick to pass under the rear
spar to the elevator bell crank.
This bell crank was origonally designed for cables but Gene Byrd gave me the control
tube he had used in his crashed KR-2S. Of course it was too long so I cut it down to
suit my needs. This tube travels near the floor to a walking beam just forward of the
stabilizer bulkhead.
The elevator control horn was also
designed to accomidate cable controls.
Here you can see the DR. Dean hinge
and the control tube attached on the
bottom of the horn. On top of the horn I
added an arm as an after thought to make
fine balance adjustments with. If I use it
to balance the elevator, it will be
welded together instead if the single bolt.
The walking beam changes the
direction of travel for the elevator
control tube and helps to stabilize the
tube system.
I have made one seat but decided to make another to drop lower between the spars. I
used the original seat and some measurements to design the profile of this seat.I then
transfered the profile to some cheap luan plywood and cut it out on the band saw. I then
made a stackup of 1" foam and glued them together and glued the profiles to the foam
with gorilla glue. Next the top sutface was sanded to the shape of the plywood and a
layer of carbon fiber is laid up on the foam. After the epoxy was cured, I fliped the
whole thing over and sanded the foam on the seat bottom to the plywood profile. The
bottom side was then carbon fibered.
