| Subject: | Re: throttle set-up |
Geoff,
I installed the Jabiru FWF supplied dual throttle system as intended by Jabiru.
Initially it did have a lot of inherent friction and hysteresis. I worked at
reducing friction at all the movement points. I put doublers on the instrument
panel and firewall where the throttle cable passes through to eliminate flexing.
I also pre-bent the solid throttle wire where it passes through the firewall
and flared up the opening that the wire passes through. This and some
teflon lube has resulted in very satisfactory operation. I worked on it quite
a bit and, admittedly at one point, was near to scrapping the system outright,
but persistence paid off. I has been operating very well in flight for over
a year and 100+ hours now.
Good luck on yours,
--------

The throttles should be push to open. The Bing carbs are spring loaded to o
pen throttle and you have to pull against the springs to close the throttle
s. You should try to keep all the major systems as standard as practical. T
here's no good reason not to set the throttles up for push to open.

. Does anyone have such a set up and has it caused any problems as opposed
to the standard push throttle? I realize a person can get used to anything,
but this seems counter intuitive. Yes, No?

It certainly should be made to work in the standard manner. However, I'm not
aware of anything in the FARs which require this for an experimental
aircraft. Those are the only standards which legally apply. I think you can
legally build an aircraft in which "push" idles it, but it would be very
foolish to do so.
I'd personally refuse to fly an aiorcraft with the throttle wired backwards.

I dunnooooo, maybe it would be fun to have "push to close" throttles,
and reverse the rudder and aileron cables. Make it a real customized
plane..........If nothing else, nobody would ever steal
it---successfully

I seem to recall reading that the WWII British war birds have a pull-to-go, push-to-stop
throttle.? I think that airplanes we furnished for their use had to
have the throttle action reversed.? I wouldn't want to fly just any airplane
with that setup, but I think if I got a chance to fly a Spitfire, I wouldn't refuse
because of the throttle setup.

Jay, I suppose I'm a devout coward, but I would probably refuse. I know darned
well I'd forget, and jam the throttle in at a critical time. But that's me.

| Subject: | A bloody safety note for annual inspection |
Hi Guys,
I nearly qualified for the Darwin award today while removing my
propeller. Id put wrenches on both ends of the prop bolts and had my
head in the path of the propeller struggling with the torqued nuts on
the back face. As each nut was loosened, the prop rotated backward a few
degrees toward me. On the 5^th bolt, I was so focused that I pulled on
the wrench with my chin tucked in and the prop, only two feet away,
moved a few more degrees and the compression released to spin the rear
edge of the prop onto the side of my skull. The force made a 5-inch mark
on the side of my head and the centerfold in my ear was cut clear through.
Wrenches and I hit the floor and then I walked from the hangar bleeding
pretty good. An airport employee saw my bloody towel in hand and called
the airport emergency team and soon medics in fire trucks arrived to
offer assistance. It could have been worse, but my mistake was not
removing the spark plugs before removing prop bolts. No ignition was
involved, but with a re-drive reduction of 2 to1, the force released was
a surprise and could well have been deadly.
I signed a refusal of medical care as my ear had quit bleeding and was
very appreciative of their arriving so quickly.
They say confession is good for the soul and that its never too late to
learn something,

Don't feel too bad. I saw someone else do the same thing with a 6 cyl Lycoming
in the 1980s. The result was similar: iot scared us all silly, but didn't do
any permanent damage.
