t sounds like you have a good grasp of the basics. Go to AC 43.13-1B
Chapter 7 page 7-29 and perform the test as listed. Your instincts are
good=2C will the cable be stressed in normal use to anything near the
design limits=2C probably not but what is the up side to not performing
the work IAW acceptable data. Make sure to follow the safety precautions
listed in the AC=2C cables can be dangerous. If you don't have the AC you
can download Chapter 7 or the whole thing from the FAA web site.

Hey Chris,
This is also on my list to upgrade as the current ones look a little anemic (like
the original rear spar attach point). Although that being said I believe that
the cracks seen in the rear stablizer were in the horizontal stabliser attach
points not the plates that this attaches to on each side of the fuselage.
Cheers

I like your design very much. It appears that the HDS bearing design is
significantly different than the XL's.
You say that the rudders are smooth and light now. The question I have is
why did Chris design in the v-notch? It seems to me that the air flow would
tend to keep the rudder centered in flight which is the function of the
v-notch. Is the steering stable on the ground without the notch?
I think that skyhawg's use of springs to avoid the direct coupling between
the rudder and nose gear is another excellent idea. Between his springs and
your bearing and firewall seals, I think you two have significantly
improved the design.

If you go to Lowe's they have a crimper that looks like a bolt cutter and
you can do 3 crimps in about 2 min.
they are by the chains and cable's in hardware and they cost like 24.00 bu
t well worth it.
just a thought

You might get more life from that crimper if you replace the washers with
larger
nes. Two per bolt. Hardened if you can find them. Keep the threads oiled
up.

Chuck,
The Zenith wheel pants were originally large bulbous front end
things for the 4 x 8 inch wheel and tire. This nose-gear fairing would
overcome the effect of rudder centering. I made my own fairings that
replaced the Zenith pants. Without pants, the need for a vee groove is
still, in my perspective, unnecessary. The rudder does center things
rather well, and on landing, you learn to keep an eye on where the nose
gear is, because with a tri-gear, my landings never see the nose gear
touch until I'm well down the roll out doing less than 35 mph. I still
don't think you want the Vee in the steering supports even though the
Vee doesn't play into things while the plane is on the ground. It only
comes into play when the nylon is supporting the gear in the air.
