| Subject: | wood gear bungee |
My experience seems to have been different from everyone else's.
I've been flying for four years using the large plastic zip-ties that are
sold for heating/ac duct work. they are really huge and you need a special
tool to ratchet them up tight. I'm replacing my bungees this year only
because I'm replacing my axle. Upon removal, they all look in excellent
condition and none have loosened. I have four of the ties on each "end" of
the bungee and I simply cannot see all four breaking at once. This should
be a routine part of your inspection, regardless of how you fix your bungees
in place, so if one or even two gave out, you should see it.
Regarding plastic degrading in sunlight, let's be realistic here. In theory
this is a valid point, but in my opinion a moot point in this regard. I
don't know of a single piet that is hangared outdoors, and when they ARE
outdoors for extended periods of time (maybe three days at Brodhead?) the
number of hours the sun is getting past the fuselage and wheels to actually
bath the zip ties on the bungies in UV is pretty minimal.
I would NOT use regular zip ties, but my experience is the big ones work
fine.
As do the other techniques mentioned, including a few not mentioned.

Hello Everyone,
My Pietenpol made it's first 2 flights on Oct 31.
We spent the summer replacing the Continental A75 with a
Continental 0-200 + electrical system.
The 0-200 has completely corrected the aft cg problem
[which is why I installed it] and now I have a large, magnificent
starter button as well !!
We were able to use the prop that was on the A75 [Cloudcars, wood, 74 X 38]
but had to counterbore it for the 0-200. It gives full throttle
static RPM 2500 and just on the redline 2750 in full throttle
level flight.
Patricia

| Subject: | Re: Wood Gear Bungee |
Douwe brings up a couple of really good points. First, there really is a wide
rage of quality in cable ties. And in this application the quality equates to
longevity. I think they are all adequate for the job, just that cheap ones degrade
too fast. Until the point of failure,they all seem to hold just fine if
properly tightened.
Cheap ties seem to get awful brittle with mere oxidation, as evidenced by my breaking
by hand old ones I've dug up in the toolbox...
Insofar as my bungees, the mode of failure seems to be pinching. That's why I
mentioned dans spreaders. Do you have something similar Douwe? I'm going to
fabricate some and install them. Also, 2rn flies a lot, with a lot of landing
cycles, off VERY rough fields. Douwe seems to be enamored with those Air Force
style soft squishy landings!
Food for thought. I've considered installing a cable tie between "turns" of the
bungee wrap, essentially making three or four separate loops. One failing doesn't
equal disaster. Second, when I replaced my bungees two years ago, one
side turned out to be cut through to about a mere dozen strands of rubber. Probably
less than ten percent intact? Yikes. Pretty sure it had been that way
for longer than I care to think about. Replaced them "just because". Had no
clue it was that bad. This year, I merely pulled the ends out of the hose clamps
on one side... In neither cae was the plane handling poorly nor was the
problem really visible. About any regular maintenance will keep them operating
correctly. They are not a normal failure point or a hyper critical item in
terms of having to be installed perfectly or else. I do have safety straps.
