We are planning to replace the standard 2 leaf spring with something stronger. Some time back it was mentioned that Aircraft Spruce sold a leaf spring set for another plane (Cub, Champ?) that went straight into the Maule tailwheel and the bolt positions matched up to the Kitfox. Can anyone say which of the AS three leaf spring sets fits the S5 with standard Maule tailwheel? We realise we will need longer bolts etc... Also Skystar was rumoured to be developing a replacement leaf spring set but I can find no evidence of it on the website. Has anyone heard anything? Kerry > > Don't just search. Find.

I made it out of a piece of aluminum about .060 x 3.5" x 20" then riveted an aluminum piano hinge on and then riveted to the trailing edge of the left side elevator aft tube. I made a standoff on the tab to mount a cable to, running it under the elevator and through the fuselage fairing for the horizontal stab, I then used a push pull cable like used on a lawn mower that I purchased in bulk from a hardware store. Then made a small lever from aluminum that was mounted just in front of my flap handle on the fuselage support structure. It was simple, quick and cheap but most of all very effective. (Didn't look to bad either) Could easily set for level flight and once finding the best setting for landing, I could set by feeling it's location in reference to the mounting hardware so I never had to look at it.

It didn't matter whether there were any springs connected to the pedals or not - as soon as that cable gave up its ghost all that remained was the possibility to apply LEFT pedal, but with no means to change the direction other than to release that left pedal and let the rudder try to find back to its neutral, straight-ahead position on its own.

On my model III, I built a small tension adjustable friction pad that is connected to a coil spring that is connected to the elevator control. By moving a short lever on the friction pad the coil spring (made from a lawn mower thatching blade spring) 'pre-loads' the elevator control to stay centered in any position. Small control movements return to the pre-set center when pressure is released. Large control movements, as in a landing flare, simply overpowers the friction pad and move the trim to a new 'centered' position. The trim does not need to be set for take-off or anything as the large control movements just push it around. When cruise flight is stabilized trim for level flight. The entire mechanism including mounting bolts etc. weighs barely one pound.

Well, actually it is more shaped like a banana but since we got your story first hand, Johannes, I'd like to ask again: Has anyone considered having rods instead of wires? What appealed to me when I decided to buy a Kitfox was its simple push-rod concept. While having no prior knowledge of aviation, my good sense told me that e.g. wires controlling ailerons, inside a wing, could be a source of problems. I like the ease of inspection of the flaperons. The only weak control was the rudder. But does it have to be?

It was an idea given to me by my Scandinavian Jabiru dealer. Obviously, the hole is smaller than the cooler so it should be, somehow, funnel shaped. I was thinking of maybe a section of a tyre's inner tube. Maybe one can stretch it enough to fit the cooler.

Now I'm trying to get the exhaust to fit better. I've got a round-cowl IV with a 582 and stock exhaust. (I think.) My problem is that the cowl is hard up against the exhaust on the right side. I'd say there's over 1/2" of interference. Is it possible I've got a "long" exhaust manifold? Mine sticks out pretty much horizontally and has two welded EGT bosses. The elbow outside of it is quite tight; indeed I don't see how I could pull the exhaust in to clear the cowl without making it a right angle and ruining the exhaust flow. I'm afraid that the lateral motion of the exhaust manifold, it being above the mount, will vibrate the cowl to death if I let it rub. Does anyone else have a similar clearance problem? Any solutions? Thanks, Guy Buchanan K-IV 1200 / 582 / 99% done, thanks to Bob Ducar. ________________________________ Message 18 ____________________________________ Time: 06:42:48 PM PST US Subject: Re: Kitfox-List: Return Springs From: Lynn Matteson --> Kitfox-List message posted by: Lynn Matteson Wouldn't have to be,Michel....it could be like model planes do and have a long rod (like the elevator on the Kitfox) actuate a horn on the side of the rudder, but a lot of model guys (me included) like the idea of pull-pulls, and toss the rod and horn and use kevlar thread on their models attached to two rudder horns, just like our 'foxes. The geometry gets a little involved sometimes, but no biggie.

Can you post a drawing or pics!!! Gil Levesque John Stoner wrote: --> Kitfox-List message posted by: "John Stoner" Hi Gill, I see no one has waded in yet, so I'll toss in my $0.02 worth. On my model III, I built a small tension adjustable friction pad that is connected to a coil spring that is connected to the elevator control. By moving a short lever on the friction pad the coil spring (made from a lawn mower thatching blade spring) 'pre-loads' the elevator control to stay centered in any position. Small control movements return to the pre-set center when pressure is released. Large control movements, as in a landing flare, simply overpowers the friction pad and move the trim to a new 'centered' position. The trim does not need to be set for take-off or anything as the large control movements just push it around. When cruise flight is stabilized trim for level flight. The entire mechanism including mounting bolts etc. weighs barely one pound.

Right side elbow and left side barrel of exhaust. P put a small sheet of aluminum rivited to the side to deflect and dispate the heat. Paint doesnt flake or fade at all. I also bought header wrap that i use on harley exhausts to wrap around the links to keep exhaust from leaking out connectors and keep the spots close to cowl from heating and burning the fiber.

I also mostly lurk here since my Sonex made first flight in June, 2003. I still fly to Lowell's Annual Cameron Park Kitfox Fly-In in June.
