I have just converted on to the club's Cessna 150 which is fitted with a Rotax 912S - same as we are fitting to the Kitfox S5 - and the "choke" start works perfectly. But I did not understand how it worked. I do now. We have carefully fitted and adjusted the choke cables on the S5 912S and in a few weeks we should be firing it up. Thanks again to the list for all of the info.

I'm just the builders helper but he was complaining the other day that after having the cables swaged they were still too slack and he would have to have it done again. He has turnbuckles at the rudder. Without actually going into it too deeply I felt the cables and they did indeed feel a bit slack and perhaps the adjustment in the turnbuckles would not be enough to tighten them up. Are you saying this doesn't matter? I didn't actually think about the adjustment of the pedals. What should we do before we do something silly? Kerry Builders helper and translator.

Then I bought the following parts that make up the turnbuckle: AN170-16LS cable eye; AN161-16RS turnbuckle fork; and AN155-16S turnbuckle barrel. The fork ends are .108" width where they fit over the .156" (or so) rudder horn. I slipped a .156" drill between the fork cheeks, forcing them a little wider, then squeezed the cheeks back to parallel. It works just dandy. Then up at the rudder pedal ends, I ran the cable through cable thimbles (spruce #AN100C-4) that went in the cable eye end of the turnbuckle, while the fork end slid over the appropriate arm on the rudder pedal. I used the normal Nicopress swaging sleeves (#28-2-G zinc sleeve) to complete the "cockpit"end of the cable. The reason I did this was to get away from the two "adjusting links" that SS has you build....some adjustment! 1/2" at a time. I realize that you can make these adjusters any length or hole spacing you like, but I also like the clean look of the swaged-on fork at the tail. I also didn't like the more recent method of bolting the cable on top of the rudder horn...it just seems awkward to me...the pull seems like it ought to be in a straight line from the cable to the horn, and with the fork it is. I realize that it's not far off line, but that's just me, I guess. I can now adjust tension on the cables, and the left-versus-right rudder pedal alignment. I had to grind a smidgeon off the ends of the rudder stop horns to allow the forks to clear when the rudder is deflected to its maximum either left or right. Sitting on the ground, this system works great...hope somebody doesn't find fault with it, but if they do, please tell me so I don't fly with it. : ) Lynn On Wednesday, April 6, 2005, at 01:10 PM, Kerry Skyring wrote: > --> Kitfox-List message posted by: "Kerry Skyring" > > > Randy wrote.. > > The springs in the adjustment mechanism take up the slack in the > cables.

I did that and it's worked out fine. If one were inclined he could use more hose clamps, too.

Maybe just some confusion as to the geometry of the rudder contfol system. With the Kitfox design, the springs only add sufficient tension to prevent the cables from slopping around. Since the Kitfox is a heavy rudder design - don't expect to fly with your feet on the floor, like my friend in his Skyklane - the foot pressure as you fly will create the tension. In other words the tension is created by the force of right foot on the right pedal with the cable going to the rudder. The left cable comes from the rudder to the left pedal where the force of the left foot picks up the pressure. The only practical value of a turn buckle would be with a Model IV or earlier to adjust pedal position - short legs vs. long legs. The desegn there has adjustable links that accommodater this. The newer models have rudder pedal adjustment build in. All tigntening the turnbuckle would do is stretch the spring. If for some reason the light tension is a problem, just get a stronger spring. I wouldn't do that though, there are just too many Kitfoxes flying out there just as the factory designed them.

Seeing as SkyStar has already modified the exhaust to the detriment of HP I doubt you'd want to lose any more horsepower. The after muffler does not cost you power (loss is 0%).. All you lose in dollars. (Geeese!!!, I'm a Rotax Service Center and I don't believe I just talked someone out of buying some Rotax stuff 8 ) ). I doubt you would notice any difference with the after muffler. Now... If you want to really quiet down your plane try this.... Add about 6 inches to your gear legs..... Change out the gear drive to a 3.47:1 set of gears....Buy a Culver 77" x 53" in prop.....Go suprise everyone in your neighborhood as this combo makes exceptionally little noise. The prop will pull an amazing 430-440 lbs. of thrust. It turns at a very slow rate of 1800 rpm at 6250 engine rpm.. It turns a very quiet 1670 rpm at 5800 engine rpm. I know this works 'cause I have built three planes with this set up. For a couple of grand you can please the neighbors to death. Just my two cents worth.. Bob Robertson Light Engine Services Ltd.

I can see the advantage of cranking the 912ULS without spark during start-up and could add a momentary switch to ground the mags. I am wondering how to properly wire the ALT side of the split master to disable the charging circuit if necessary without causing damage to anything.
