First of all let me say that after a very stressfull 6 months I am able 

to keep the plane. Also all that is left is to get current and will be 

back in the air again.

Now for the question to those of you with bungee gears still. How many 

wraps are you running? I am running the recomended number but it sags 

just a little and is very bouncy on landing.

Al, what is your tire pressure? Which tires are you using?



I've got the Carlisle ATV knobbies, at about 3-4 PSI. No bounce at all (at

least not the plane's fault <g>), and I've been told that my bungees are too

loose. I disagree, but since I didn't put them on, that may be true.



I don't sag at all statically, but my toe-in pulls them out a little when I

push back into parking. I have to lift the right wheel and move it in, so it

doesn't sit that way overnight. 



BTW, I've got 5 wraps.

Al

   

  I have the same problem.  I am thinking of making the bungee about one turn longer.  I often land on very rough fields and like to have the bungee absorb the shock rather than transmitting the load to the frame.  If you try this before I do please post your results.

.. and I have got 6 wraps. My bungees are 7/16" thick and 55" long, 

unstretched, from eye to eye. After 13 years, they are sagging a bit. 

So, I went to buy some bungee cord and made myself a pair of new ones. 

Alas, bungees don't come only in different thickness but also strength, 

or rather, resistance to stretch. The new ones were way to soft!

So, I put back the old one on and ... it's ok for the time being. 

Interestingly enough, they  only sag when I am not flying for a while. 

The moral of the story is: I have to fly more. Please could you send an 

email to my wife, telling her I have to fly more? Thanks in advance! 





Cheers,

Michel

Dear Mrs Verheughe,



I have consulted a number of colleagues regarding Michel's sagging

condition, and the consensus of opinion is, that the condition, usually

found in males, relates specifically to his corpus avion.



Typically, this condition occurs when insufficient stimulation of this

part occurs, or occurs at irregular intervals, such that it's performance

degrades over time. While mechanical intervention may be indicated in

extreme cases, a simple remedy first to be applied is, to correct the

lack/irregularity of use.



Reference to the literature indicates that, the active and positive

support of one's spouse has a direct and positive effect on outcomes. His

recovery may be immeasurably enhanced by your personally

encouraging/inviting him to more, and regular use of his flight skills.



Regards

To clear up how many wraps I have. There are 8 cords on my landing gear.

about these shock cords ,, My series V manual says 8 wraps on the P/N

63003.101 bungee cords , i know for a fact that on mine 7 wraps were not

enough to keep it from sagging and eight worked fine . and 8 wraps were very

difficult to achieve ( at least for me ), good luck with the wrap session

Yes, I did the mistake to forget mentioning that I had a model 3. I 

guess the model V is heavier and needs more turns. In any case, the 

model 3 is certainly not meant to have more than six because there is 

already very little place for six turns and if I had to add a couple, 

they would have to be on the top of others, and that is not wise, is 

it?

And I agree, it takes two strong men to pull the bungee to a fit around 

the bars, one under and one from the inside.



Cheers,

Michel

I have a Model IV with 5 wraps instead of 6 and it works fine. 

I have the 7/16s  Bungees as well.   I think they have 3 stripes on them. 

My empty weight is under 550 lbs though.

Michel I think the Model ll and lll take the same size bungees which is 

60" long and 3/8" dia. If you would like I would be glad to check the 

size and color. I read some where that one of the colors that had been 

used was bad and no long recommended. I have also read that some 

builders have made the sixth wrap when the bungee began to sag.

Hey! I found a way to do it solo that's not too bad. You have to be careful 

though.



I first wrapped the bungee as many times as I could and hooked the end over 

the lug. (I think I got three or four wraps.) I then, using channel-locks, 

(a type of plier with a lot of leverage and a lot of grip area,) and 

working from the center wrap to the outside, pulled all of the "slack" to 

the last loop. This left the last loop with enough slack to disconnect it 

and gain another wrap. Re-connect the end and go through the process again. 

I was able to get my full six wraps doing this. You have to be careful that 

you don't damage the bungee by crushing or tearing it. I found it wasn't 

too much of a problem.

as has been suggested before, the use of large wireties as each loop is pulled as far as it will go allows the carrying of the slack to the end. Others have used a wood wedge jammed between the bungy and the frame carry through.

FWIIW, an excellent tool for pulling the shock cord without damaging it is a 

(pliers?) made for pulling spark plug wires off an auto while it is running. 

NAPA has them.Mary and I can now install one shock cord on out 4-1200 in 

about 10 minutes.   Larry Huntley

Sorry for the late answer, Dee, I am getting email from so many 

different lists, and in three different languages ... I am getting 

confused.

Yes, thank you. The size is quite evident but I am not sure I 

understand the idea about the colours. I "googled" a bit about it and 

it seems that colour code is used on chock absorbing cords as an 

indication of the date of manufacture. What I don't understand is, are 

there different strength of bungees, or rather, different stretching 

lengths? Because I have the right diameter, the right length as 

indicated in the building manual but ... it still sags. Should I get 

another type of bungee, in which case, which? Or should I make the 

length (now 55") even shorter?



Cheers,

Michel

The bungee on my Model II is 3/8 dia. and 60" long.  Looking at the gear =

This is what is needed for Coloured  Bungees  

We refer to it as MIL SPEC   



Most aircraft supply houses carry it.  

It is 3/8s sizing but you will find it measure about .41

Thank you, Dee and Dave.

I purchased this - now useless - bungee cord at a local ship chandler. 

I didn't see why requirements to quality would be different from 

aviation to maritime use. Yet it must be because if what I purchased 

was 60" long, it would sag way too much. So, aviation bungee cord 

stretches much less than their maritime equivalents. It doesn't 

necessarily mean that they are stronger but they stretch less. However, 

they are both strings of rubber in a nylon sleeve. Could it be that the 

aviation one is pre-stretched in some way?



Thanks for the link, Dee. I know that Aircraft Spruce also retails 

bungee cords. I might have to purchase from the other side of the big 

pond but, as you know, given the shipping cost, the enormous 25% added 

value tax in Norway, on both goods and shipping ... it makes me try 

first local goods. Yet, if not available, I'll do in the US as I have 

done many times before.



Cheers,

Michel
