Chrissi,
You do it deliberately. I know you do.
Good luck getting a big enough throttle body. I hate to admit it now,
but I
need one too. Let me know what you decide on.

John ... uh, do what?  (she coyly twirls a lock of hair)  ..actually I
am clueless.
Are you saying you are throttle body impared?
Paul, so what would be the ultimate would be a 3.125" sealed slide
throttle, ala Ellison TB on steroids?
...Chrissi


Yes something like that. Slide throttles are difficult to make because
they
tend to stick when there is a large pressure differential across them.
some sort of ball bearings are essential. I have never taken an Ellison
apart however to see how they do it. They may not consider this a problem
in an aircraft application. A few  race car drivers were killed
in Europe because of sticking slide throttles. I am not taking any
chances.
Perhaps one difference is an aircraft throttle is controlled by a push
pull cable while race cars typically used a pull cable and a spring
in the old days.

Paul,
The Ellison Fuel injector has two strips of teflon about 3/16" square in
slots in the aluminum slide.  Never had mine stick yet.  Have a slide body
for my 13B designed in my head.  Should it be successful it may be a
break-thru.
Maybe not.

Fly fast, land slow.
