I am in the process of hooking up my aileron cables and was wondering if itis better to locate the turn buckles inside the wing and cockpit or is itok to locate them at the aileron horns. I know that they would create lessdrag inside the wing and cockpit. They sure would be easier to install andadjust out on the wing. Any comments on this will be appreciated. Anotherquestion I have is how much aileron travel is the correct amount? Thankjasjimsury(at)fbtc.net________________________________________________________________________________

I'm no expert at all. Once somewhere a long time ago I saw a pietenpol withone aileron turnbuckel. It was on top of the wing exactly over the center. Iremember it because I thought at the time it was so strange,but maybe clever.Cheers Steve Yahn>I am in the process of hooking up my aileron cables and was wondering if it>is better to locate the turn buckles inside the wing and cockpit or is it>ok to locate them at the aileron horns.

I just finished installing the aileron cables on my GN-1 and see that Ihave a small problem. Seems that when I deflect the ailerons fully thecables get loose. I was just wondering if any of you have experienced thesame thing. The ailerons horns are identical as they were shaped whilebeing bolted together. Is this the norm or what? Where might the problembe? If I tighten the cable with the ailerons fully deflected than thecables are too tight in the neutral position. Anybody have any suggestionsas to where I might look for the problem? Thanks jasjimsury(at)fbtc.net________________________________________________________________________________

What I realize is that I will never deflect thestick to full travel under normal conditions. What I did was to nicopresstwo short cables to my down elevator cable and add a heavy tension springapprox 9" long between them. I then adjusted my cables so when I had fullup elevator the tension was correct and as I push forward stick the springpulls slack in the cable. In case the spring would ever break or come loosethe orig cable would still be intack, it would have some slack in it butyou still could fly it.Hope to be in your postion in riggin ailerons soon.

The rudder is easy. You need stops to keep the rudder from banging intothe elevators. I set mine with 1 inch. clearance. The elevators are alittle harder. You need enough up elevator to flare at low speed. That youhave to figure out.I think I found out why my cables go slack at full aileron deflection.There is some difference in the distance between the pivot point of theaileron and the ends of the horns. Not a lot but it is there. Looks like Iwill be remaking the aileron horns. jas>>I just finished installing the aileron cables on my GN-1 and see that I>>have a small problem.

I had the same problem Douwe. Congratulations! This just shows that youraileron horns are square with the torque tube (if they are square, thecables can't help but hit each other).Problem was solved by judicious application of a hammer to one side of theaileron horn on the torque tube. Just bend one of the horns (or both, butin opposite directions) enough to give some clearance between the cables.Depending on your enthusiasm with the hammer, you might have to enlarge theholes where they pass through the plywood under the instrument panel tomaintain clearance.Jack PhillipsNX899JPRakeigh, NC-----Original Message-----
