|

Guys,
I added the shock cord to the nose gear leg today and I am wondering why it is so difficult to move the rudder pedals. The shock cord holds the gear very tightly into the V groove in the Nylon block. I can see that once the engine weight is added it will take some of the pull out of the cord. It seams to me that it might be OK on the ground but in the air it will be very hard to move the rudder. Am I missing something here?

Chuck,
I thought the very same thing. However, it proved to be of no concern. It works fine on the ground and in the air. I think my experience is pretty much like most others.

Chuck,
Rudder movement is easy. The resistance you feel is because you are on the
ground and the rudder and nose gear are connected. All is okay with
movement. BTW -- don't land with a cocked nose gear with this setup.

Chuck,
Although most have found the extra friction acceptable, it is still
higher than production aircraft plane I have flown. I find it to be
marginal to make really nice smooth rudder corrections, not impossible,
just not as nice as the other extreme (a Grumman AA-5). Note that when
you tighten the rudder cables the friction will increase some more.
Be sure the two half's of the bearing block are not too tight. Also
you need to lubricate the block. This is another thing I never liked,
having exposed grease in the engine compartment. Not much we can do
about it.
After I get the plane back together, I am going to be looking for
nice ways to reduce the friction as seen in flight.

Don't forget that the rudder cables will loosen significantly with weight on the nose gear. The tension should be set with the nose wheel off the ground. I originally set my cable tension with weight on the nose wheel, after I properly set it with no weight on the wheel, it took a lot less effort to move the rudder in flight. Now on the ground, my rudder cables are almost slack.

I build mine without the "V" notch for 2 reasons: 1) lowers the resistance
2) I don't like the way the "V" notch makes the lower plate flex when
turning the nose gear left and right. (note. then bungee isn't the one
that gives, it is the bottom plate

Chuck,
The nylon block probably doesn't need a vee groove for the nose
strut steering arms. When the gear is hanging, the steering arms weigh
in on these grooves
and cause the nose gear to become stiff. I made my nylon blocks
flat after having that experience and now they are very smooth and light.

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.
