My landing gear bungees now sag enough to raise the strut plate a  

good 1/2" above the wing surface when parked.  This is relatively new.



These bungees were purchased with the kit circa 1995 ... I guess it's  

time to replace them even though the airframe is still low  

time ....?  Is there a "specification" for how much sag is allowed?



Does anyone have a good source for these bungees?  I recall  

discussions a few years ago where there were some issues finding new  

bungees of the appropriate length.  Is this still a problem?



Thanks in advance

Grant,  Zenith says they are 1080HD bungees.  ACS has them listed as 

Mill Fresh Shock Rings 

<http://www.aircraftspruce.com/catalog/lgpages/shock_rings.php> size 

1080HD for $19.30 each.

Leo - thanks.  I ordered them at ACS - but my link shows 35$US each  

for the 1080HD. fwiw

I searched the archives and I think that in the past some builders  

had problems but it might have involved subbing a 1080 non-HD?  

(stretchier?), or a 1280HD (3/4" thick vs. 5/8") ...



At the same time I'm installing Mac Machine's lower gear plate  

upgrade (to 1/8" by 90mm) and the plastic bearings top and bottom on  

the struts.



Does anyone happen to have any good sequential instructions for  

changing out the bungees?  It's been a long time since I assembled  

all that and I did it on a work bench.  I'm not looking forward to  

doing it now from under the plane, in a 'dirty' gear box with  

accumulated dust and grease...



You can be sure I thought deeply about changing the whole thing over  

to one of the spring/steel legs ala XL but... $$$ and total weight  

tipped the scales back to the original gear legs.



Thanks all

Grant
