Re: X-Air Ultralight Aircraft Hanuman suspension bungee replacement
|
Hi guys, I've had no luck finding the right bungee for my Hanaman so used 4 shock cords # 9044 from Aircraft Spruce. Did fine for 4 or 5 flights but with 2 on board and a full load of fuel the gear got weak so adding 2 more 9044 shock cords. Made my own tool to stretch cords from threaded rod and tubing. Used picture of tool selling on Barnstormers as a guide. Works great. Good luck with your bungee replacement.

Hanuman suspension bungee replacement
?
?
I had a similar experiance with my Xair 'H'.
The? original kit bungees did take a lot of effort to install.? I
did get the 9 strands on but had to pull so much that?they were at their
elastic limit, not leaving any left for actual suspension flex certainly not
the 2" plus required.
?
When I came to replacing them?I experimented
with different?bungee diameters, 12mm
looked promising but had trouble getting them in the space behind the nylon
washer, I inserted longer bolts but they bent. I went back to the 10mm and
found that less that 9 strands was to soft, 9 strands bought me back
to?the elastic limit. Thats how I left it, not very satisfactory but at
least I don't now rock and roll taxying.

Hanuman suspension bungee replacement
?
After flying my Hanuman for 6 years, I decided to replace the
bungees on the suspension with new bungees from RandKar. I bought these
bungees a few years ago and have stored them inside my house.
The manual calls for 4.5 revolutions or 9 strands in the center of
the loops. I have been unable to stretch the bungees more than 3.5
revolutions (7 strands) and it was very difficult to get that far. I must be
a weakling but is there a trick to getting them stretched to 9 strands? Even
with 7 strands, the bungees are tighter than the 9 strands that I
removed.
Advice? Thanks in advance. Superhuman strength is not
available...
