boyd,
Thanks for the response,
My main problem now is that the landing gear keeps bending, just from going
up and down the runway.
It bends in the tapered portion of the aluminum legs, Is this taper for a
reason other than weight ?
I have been thinking about making adapters to put 1 1/2 inch fiberglass in
place of the aluminum, also going to try cable bracing on the existing legs.
I have a couple of dips in the runway that are not to kind to week landing
gear.
I don't own the property and the land owner for some reason doesn't want me
to do anything to it to smooth it out.
He also uses the surrounding field for hay.
I have a CGS hawk single place that has fiberglass landing gear and it
handles the dip fine.
thanks,
Lee

Hi Lee,
Hope you don't mind my butting in and adding my 2 cents worth.I had the same
problem with my firestar. I weigh 235lb.and just a short taxi over moderatly
rough ground would
bend the alum gear. After talking to Larry Cottrel out in Oregon and Travis at
the kolb
factory, I bought some 4130 tubing from aircraft spruce I don't remember the the
size
or wall thickness( I'm sure Larry or Travis has that and the heat treat #) and
had it
heat treated to make it springy. Kolb will tell you the down side of this change
is if you have a
really rough landing you will bend the cage but that the soft alum gear is
designed to bend and
save the cage, be that as it may after 200 hrs and plenty of MUCH less than
perfect
landings, lots of them off airport, my gear is still as good as new and my cage
is fine.
Hope this helps.

Here is part II of today's flight. The names of places on the maps may or
may not be the same as the ones known to the locals. In other words I may
have some of the place names a bit off.

lee
the taper would be for weight and also flexibility... if the gear was
too ridged all the shock of a rough landing would transfer to the cage.
some on the list have made their own gear from round tubing, cut fit
welded to shape, then heat treated to spring steel. somewhere in the
back of my mind, it seems Kolb used some fiberglass gear, but went
away from it, I don=99t know why. if you look in the archives,
and do a search for straightening alum gear,, there will be some
information you can find. seems you could only do it a couple times
then had to buy new. I don=99t know about cable bracing...
seems that would make things a bit ridged.
good luck

================================================================
Having lots of experience in bending landing gear, I believe that I might
be an exdribble in the matter. (Not quite enough to qualify for exspurt
quite yet. ) I think it might be the only case wherein Kolb has misjudged
the damage factor between alum crumbling and causing a wreck, and spring
steel causing malformation of the cage.
One of my mishaps involved bending the landing gear far enough that the
wheel turned, (Dropped it about 5 feet over a fence with the early smaller
gear legs) and threw me into a ditch. The cage definitely bent and not from
the impact.
I have several times on a landing that I thought wasn't all that bad, ( for
me at least) actually had enough compression that it would close the Master
switch. ( It was a pull switch mounted flat)
I got tired of the alum gear and managed to obtain a set of 4130 legs
tempered to 46-48 Rockwell, and found that the spring of the 36 inch legs
is a lot easier on the plane than the alum. If you hit hard, the spring of
the legs will cushion a lot of the jolt, which I never found to be so with
the Alum legs. Of course there is about a foot more leg sticking out than
the alum and that would also be a factor.
I am sure that my landings have gotten a bit better, but I have not bent
anything nor shut off any switches since changing over.
I believe that Travis could help you out with a set, and my opinion is that
it is definitely worth the effort and cost.
