Posted: Mon Dec 18, 2006 12:31 pm Post subject: control cable question

I am currently making the control cables for my 601xl,

and the drgs call for the turnbuckles for the elevator

cables to be attached to the stick. During contruction

this is almost doable if installed before the armrests

get rivetted. Afterwards, it is virtually impossible

to get to let alone safety wire if it needs

adjustment. My question is: is it OK to attach a

shackle and a short length of cable (enough to reach

the access panel in the fuselage), and put the

turnbuckle where it can be easily accessed half way

down the fuse?

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  That's exactly what I did. I figured the lengths necessary to put the  turnbuckles in close proximity to the access hatch, then threaded the wires,  made the loops (don't forget the thimbles), swedged them critters, and attached  turnbuckles. I don't think it makes any difference where they are, as long as  you have them, to set cable tension. Why ZAC puts the turnbuckles there is  beyond me, unless they intend for you to rivet the armrest way later.

I have dual sticks in my plane and did not like the fact that I could not 

get to the bellcrank under the covers. For that reason I used nut plates and 

bolts to secure the arm rest cover, that way i can remove it anytime i would 

like.

ken: I figured the same on access.  I reversed the bottom cable,(upper elev) and put the turnbuckle back at the elev horn under the fiberglass. I had nick look at it when he visited my hanger and said it was ok. Still works fine. jack in los osos ca

Ken-  I hinged my armrest at the rear with a piece of leftover piano hinge, 

put a cross brace from oneside to the other and covered the lid with 

leather.  I can access the turnbuckles by lifting up the cover.

With the dual stick option, you there are two armrest cover plates.  I, also, hinged the rear one; and fastened both converplates with nutplates.  I kept the upper turnbuckle within the armrest, but placed the other one at the upper elevator control horn.  I am fastening the fiberglass "saddle" with nutplates so I can access the turnbuckle.  



I also found that I could not install the horizontal stab. with the rearmost upper skin (with a carefully coped cutout) in place.  I cut off the upper skin to within about 40mm of the rear bulkhead and made a .016 fairing to close the gap between the upper skin and the saddle.  It too, will be fastened with nutplates.

Ken, I left the upper turnbuckle attached to the stick and put  the lower turnbuckle near the belly access door.  An alternative is to  attach at least one of the center console sides with platenuts and  bolts.

Posted: Wed Dec 20, 2006 6:52 am Post subject: Re: control cable question, and XL elevator sensitivity

Does anyone know of a device that would desensitize the XL elevator motion around neutral, akin to the exponential function on radio control transmitters?  Flying in the Zenith demo, it seemed that for gradual-to-moderate turns much more stick deflection was needed for ailerons than elevator while holding altitude in the turn, and slight stick adjustments made for big pitch changes.

For those who fly XLs and other light planes, is this a big deal, and would there be a benefit in smoother flying with an elevator that had less deflection relative to the control stick around neutral, then catching up for full surface deflection at full stick?

Thanks for your inputs

It is a lot less noticeable in the dual stick version. This is probably because of the stick position rather than any real change.

I suspect that CH probably intended it that way. He certainly designed the ailerons and flaps thicker than the wing to accentuate the response rate. Elevators that are blanked by the stab tend to have a dead zone around neutral but once active they still are at the same rate.

On the Flight Design CTSW 2006 they have springs attached to the yoke to make it less sensitive and feel more like a Cessna or larger plane...  Night and day difference from the 2005 CTSW.  It works great for that model...  Not sure what people think for the Zodiac
