Thanks for all the ideas for the bungee replacement.Now I have a good way to do it. One other question though.With new bungess did the gear droop at all or was it right up against the stops. My gear is drooping about an inch to inch and one half from the stops at center fuselage.It doesn't appear to be that bad but I have ordered the bungees from John so I will have them on hand as it appears it won't be too long before I have to replace them and I always like to be prepared

        Thanks again for all your replys !!!

I think I got a set from john and was back in the air in a few days.  I believe these should be changed at least every two years.  However I would not order them until you are getting close.  The set we got with the kit sat inside for about 4 years but lasted less then a year in service.  With that said I think the aging starts weather they are stretched and in the elements or not.

Dick, with new bungees the gear should be tight against the bottom of the fuselage with two people sitting in the plane.

Hi Dick.

   

  Alot of great ideas to replace bungees. I've tried many of them, twice. Haven't yet had the one-man "easy" experience though. It was more like the "2 guys with badly busted knuckles quitting for dinner and coming back after cooling off" experience.

   

  The bungees should hold the gear tightly against the rubber pads. If it doesn't, either they're too long or you haven't got enough turns yet (7 as I recall). That last turn is a bugger. Enjoy!

   

  Happy new year to all you Kitfoxers.

Mine is against the stops when empty.

Guy,

    Thanks for the excellent bungee replacement procedure! I have copied it and will use it as a guide along with the other suggestions, when I replace them.(Right now they are being made)

    I found out yesterday that I have some gear misalignment.  As I push the aircraft into the hanger the gear droops about 1 1/2 inch from the stops and as I go forward about 15 ft it tightens up against the stops. So, I have some toe in on the gear. I also had this on a Luscombe I use to own and some of the old timers suggested I get a big piece of pipe and put it on the axles to bend the gear into alignment as that is how they use to do it. I just lived with it instead.

                                   Thanks again !

I had bungee's on my Model IV.  You must keep them very tight.  If you can see them moving when you taxi around, they are too loose.  They are designed to move if you land hard, if the wind gets under a wing and the bungee sags you will be doing wheelies on the runway or taxiway.  I have spring gear now with 6 ply aircraft tires.  A very different airplane in the wind.  Clint 1300 hours

Be careful with this. If you have any camber, as I do, there will 

always be "apparent" toe in when in a three point attitude. (Camber 

is when the bottoms of the tires are closer together than the tops.) 

If you picture rotating the aircraft so it points straight up and 

then setting the tires on a table, you'll see the maximum extreme of 

the toe in associated with camber. Even though it's much less in a 

three point it's still there. (Toe-in due to camber will 

theoretically be zero when the fuselage is horizontal.)



My plane has a bunch of camber resulting in about 2.5 degrees of 

toe-in in a three point attitude and about 1 1/4 degrees when the 

fuselage is horizontal. I have no problem with this configuration 

other than that I have to replace my tires after 200 hours and ? 

landings. I think the reason for my camber and toe-in is that when 

the plane hits hard and the camber goes negative then the toe-in will 

go to zero. Just a theory. (The original builder built beefy new tube 

gear with more camber and a little toe-in.)



You'll see many toe-in arguments in the archives. I personally 

believe toe-out is theoretically better, but as you can see I've been 

flying with toed-in tube gear and have had virtually no problems in a 

wide variety of conditions: high speed, low speed, wheelies, 

three-point, crosswind, pavement, dirt, and mud. Go figure.

I think that the toe out situation is far worse than the toe in .Just my .02

Thanks for the pic, Michel. Others who have solved the bungee replacement issue would really help the rest of us by posting videos of your procedures. Written instructions are helpful but, as they say, "one picture . . . . ."

  Happy new year!

I can't say if I have a camber because I never tried to measure it. 

Nothing is apparent visually, though. I do have a slight toe-in, which 

I realised when I installed my wheel penetration skis. When I push the 

plane in the hangar, the gear also droops but once in place, I lift one 

wing and the gears get together again and the bungees are tight.

Incidentally, here is a photo of how I made a tourniquet to keep the 

gears together when I replaced the bungees. My son is under and I am 

with my head inside the plane.

See you next year!
