| Subject: | Re: New style Nose Gear for the 701-801?? |
What I do not like about the 701 nose gear is the solid rudder pedal connection.
I intend to set my up with a spring type connection like the tailwheel on my
piet. Hopefully this way the tire can align itself (xwind landing ,etc.) if it
has to eliminating stress.

For what it's worth, here below is the response to my request of info about the
availability of the nose gear for the 701 from Custom Flight Systems.
The reason for my curiosity of alternate designs of nose gear (or anything else)
is that while tried and true, any design or initial concept can be improved
upon in time, especially when it comes to safety improvements. When looking
at the incidents involving nose gear on the 701 and others, the bending of the
axle allowing tire contact and lock-up, the "fold back" of the gear tube at or
near the lower bearing contact area seem to be consistent issues when sufficient
hard contact or"arrivals" are made. I read about thicker axles being made,
even of solid stainless if i'm not mistaken. In looking at the axle wheel assembly
I can understand that due to the requirement of the tire width versus the
width of the bearing hub that there is not much support to deliver the force
of impact from this bearing hub suspended in the middle of the shaft, back through
the wheel fork doubler, then tube and bungee. Solution? If not stonger
axles, how about a support
brackets added to the ax!
le shaft spacers that would deliver some of the impact back through the fork doubler.
Or both.
When it comes to the nose gear tube folding back, perhaps having a much wider
bearing contact area, (flange bearing ?), may help as this would spread the side
(back) force to eliminate the pressure point effect of the 1/4" thick nylon
lower bearing. This might eliminate the consequence of the initial denting to
the side wall of the tube which weakens it's design strength, allowing the tube
wall to collapse.
These are just my thoughts, please pick them apart, any and all comments are welcome
for the safety of our sport.
Thanks in advance and Merry Ho Ho ......... Don
Hi Don,
We had a inquiry from a 701 owner in the past but no one has installed our nose
gear on a 701 to date. The steering shaft is (OD 1-3/8 X .095 thk and 22 long)
We can make some modifications if needed. A 1-7/8 X .250 thk 4130 tube cut into
bushings will adapted our nose gear to the 2 tube. (PN 03-10600 McMaster Carr).
We are using 4 springs with different spring rates instead of heavy and
expensive hydraulic damping systems. The rebound has not been reported as an issue
to date.
Thank you
Wade Custom Flight Systems.
