Hi Geoff,
I didn't like the feel of the included dual throttle kit from
JabiruUSA either. I decided the problem was the fact that the torque
tube was mounted on the shelf above the nose gear and the control
path is even higher at that point because of the direction of the
arms on the torque tube. This is natural since it was part of the
firewall forward package and that was the only place forward of the
firewall to mount the torque tube.
On my plane I decided to move the torque tube to aft of the
firewall. I mounted it at three points - two side skins and below
the center channel that runs between the firewall and instrument
panel. Also I faced the arms downward to keep the control path at
the same level as the throttle connection on the carburetor. Rather
than using the supplied torque tube, I reproduced the design with
longer arms. I also mounted the throttle knobs and carb heat knob on
the side skin -- my arms aren't long enough to reach the instrument
panel while leaning back in the seat. The result is a very smooth
dual throttle implementation.
If you look in the archives you will probably find some pictures I
posted of this design.
The bad news is it took me a couple of months to implement this along
with a redirection of the carb heat control.
Good luck,
Paul

Thanks for the reply - sounds like a great idea. Any chance of reposting the
pictures of your design? I found your previous comments in the archives but
am unable to access the pictures.

Hi Geoff,
I'm not really sure I ever posted the pictures to the group
site. I'm sure I sent them out, but perhaps it was only to a few
people who asked. In any event, here they are. I hope they help . . .

Lacquer thinner - wet the paper and it peels right off. A quick wipe with a towel
removes the residue. Also does a nice job removing magic marker.
