Hi Guys,
I'm running an O-200 on my 601 and will be using aluminium tubing instead of
the supplied 1/4 inch hose. What size ID are others using for an O-200?
Cheers

Tubing is generally listed by OD, 3/8" OD tubing should work fine.
That will give you a bit more than 1/4" ID.

PETER- I would use 3/8 O.D. aluminum tubing as a replacement for the rubber
hose . It has a 1/4 inc I. D.

Hi Guys,
Thanks for the response. The reason for the question was that all parts
supplied by Zenith (gascolator, fuel tank) use 1/4" npt, the fuel pump uses
1/8" npt. The O-200 uses an MS3SPA with 1/4" fittings. I'll go with the 3/8"
tube and adaptor fittings for the fuel pump.
Cheers

| Subject: | Re: One bungee on each Main Gear |
Hi Damien,
I think that would be a really bad idea. I am an aircraft designer and have been
designing landing gear systems for about 25 years (on UAV's). A landing gear
system is designed to absorb a certain amount of energy during the landing event.
For a light wing loading aircraft like the 601 the limit descent rate is
about 6 or 7 feet per second and that equates to a certain amount of energy. The
gear absorbs the energy by deflecting a carefully selected distance with a
certain amount of opposing load (in this case from the bungees). If you remove
one of the bungees you are basically cutting the amount of energy the gear can
absorb by half before the gear bottoms out. Once the gear bottoms the loads
go up very quickly to the point that something is going to break. With one bungee
your gear would only be able to absorb the energy from about a 4 FPS landing
event. Feels great until you really drop it in and then you have bent something.
Just a tip,
Jim Machin
