I got factory rebuilt gyros from RC Allen / Kelly Manufacturing
www.kellymfg.com/
They were $400 a pop (vacuum) and really just like new - ask for Shirley
I'm using a so-called 9" venturi from Aircraft Spruce and a Rapco
regulator -
suggest you shop for your fittings from Rapco - I used standard An
fittings only to be told by Rapco that they studied on it and found the
90ยบ bends in the An fittings robbed a lot of air flow - wish I could do
it over again, but my gyros seem happy with the 3" - 3.5" (indicated)
that they get with the dropped pot of spaghetti - the hoses that tie it
all together.
