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.

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.

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.

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. Larry McFarland 601HDS at www.macsmachine.com Terry Phillips wrote: > > Larry > > I like your design very much.
