I think it was around $900 when I bought it new. I'd like to get $500 for it. I would prefer local pick-up in Lancaster, California. I still have the original shipping box, but UPS shipping would probably run around $100 because of the oversize length of the box.

From: "Louie928" I wondered the same thing when I saw the aileron bellcrank. I made different ones using a ball bearing for the pivot bearing and bronze bushings for the cable clevis attachments. The bearing and bushings are from Aircraft Spruce. The new bellcrank is a bit lighter than the original. The thickness is the same so the original attachments can be used with the holes drilled to fit the ball bearing ID. -------- Louis W.

I cannot say for the aileron bearing. However, it is certainly true for the upper rudder bearing on the HD model. I made a new part after three years of flying. After removing the part, however, I did feel that the part was still safe (plenty of edge distance and no noticeable fluttering or vibration in flight). ---------------------------- Michel Therrien CH601-HD, C-GZGQ http://mthobby.pcperfect.com/ch601 http://pages.infinit.net/mthobby ________________________________ Message 5 _____________________________________ Time: 09:02:52 PM PST US From: Terry Phillips Subject: Re: Zenith601-List: Re: Aileron bellcrank wear? Louie You are a true craftsman. You new bellcrank is a work of art. Do you have a drawing of your design? It looks like a very good design improvement. I'm thinking that I will replace the nylon fairleads for the aileron control cables with pulleys. My hope is to reduce the drag in the aileron control system, and thereby improve the control harmony. This would not be a possibility without aileron counterbalance, but with the counterbalance, it should not present a problem. I'm wondering if anyone else has put in pulleys?

Hi Terry, Before you invest a lot of time and money in changing fairleads to pulleys, I think you should consider another aspect of the "Control Harmony" issue. The Zodiac XL has HUGE ailerons. This means force applied to the control stick doesn't require much movement of the ailerons to produce roll torque. It also means the ailerons work quite well all the down to stall speed where most spam cans lose nearly all control effect. I believe it is the geometry and size of the ailerons that makes them feel so stiff in flight rather than any drag in the control cables. Good luck, Paul XL fighting main spar rivet removal for the upgrade. -----Original Message----- From: owner-zenith601-list-server@matronics.com [mailto:owner-zenith601-list-server@matronics.com] On Behalf Of Terry Phillips Sent: Sunday, June 20, 2010 8:38 PM Subject: Re: Zenith601-List: Re: Aileron bellcrank wear?

Terry ________________________________ Message 7 _____________________________________ Time: 11:35:41 PM PST US Subject: Zenith601-List: Re: Aileron bellcrank wear? From: "Louie928" Hi Terry, I do have a drawing I made just to see if it would work. I Printed out a full size example and cut it out from cardboard. I can't remember if any slight changes were done when I cut it from aluminum. I don't think so. The drawing was done in Solidworks. I exported a .jpg file of the drawing so the quality isn't so great. The bronze bushings are Aircraft Spruce P/N FF303-01. Look under Hardware, Bushings. They are $0.19 each. Drill the bushing hole in the bellcrank slightly undersize and press in the bushing. The bellcrank bearing is Aircraft Spruce P/N BC4W10 (AN218-4). Look under Airframe parts, Bearings. It costs $18.95. This bellcrank doesn't require any changes to the normal mount and the geometry is the same as the Zenith bellcrank. Use a washer on top and bottom of the bearing to insure the bearing housing doesn't rub on the support when you tighten the bolt. I don't know how much drag the fairleads would add to the aileron movement. The cables don't move very far to give full travel. It'll be something I'll check when I connect the controls. BTW, the SS rivets work great. Thanks Louie Terry Phillips wrote: > Louie > > You are a true craftsman. You new bellcrank is a work of art. Do you have a > drawing of your design?
