I would strongly recommend getting the original cord from the manufacturer. So many have tried with hardware store bungee but it is just not suitable. You cannot fit shock absorbers on the Hanuman model that I am aware of because the shock absorber does not work in compression it works in extension and that is why they use bungee cord. If there was some sort of reverse shock absorber available then I am sure you could get to work but it is under extension not compression.

We have replaced a lot of parts for people who have used hardware store bungee which has failed on the first landing on some occasions even in the hanger when the aircraft is just sitting there. One example was it failed and the wing drop down on the workbench putting a hole in the wing fabric courtesy of a vice attached to the bench....? Just by the correct stuff that we know works and get on with flying.

I'm considering changing the bungees on my undercarriage, they seem a bit tired. I have seen some people replace them with gas shocks, which I would love to do, but don't know the details of what would be done. I haven't found any kits, and I'm not super familiar with the specs of shocks. I was told one fellow used the kind on dirt bikes, but nothing more specific than that.

Has anyone swapped to shocks, and if so, what were the parts and how did you do it?

Has anyone replaced the bungee cord? If so what kind of cord did you use and are there any tricks to it? (I know to wrap it with the weight off, but that's about it)

?

Thanks!

Tom
