Jeff,
I'm not sure that is true on my cylinders. I installed a fitting
in the top and tubing out of both cylinders and vented them through the
bottom of the fuselage.
I wish I could follow your advice on the tubing size but it has
to be fished through several holes that I know I drilled just big enough
to get the 1/4" tube through. The brake line is entirely built in until
it is in the cabin. If I could do it over it would have been all aluminum
tube.
I was actually thinking about using a short length of braided
hose in the wheel pant to connect the caliper to the polyflo tube as I
was a little concerned about vibration and work hardening of the aluminum
tube and there is not much inside the wheel pant area that I would want
to mount brackets to either.
