bungees... again

[jean.poirier]

Hello

Has I told before, I bought 12 x shock cords rings #9044 from Aircraft Spruce (by far the best price over all other supp.) to replace the single piece Murphy bungee. I made a tool to fit them on the bolt.
First 8 already installed (do not put your finger on the bolt when the cord fall from the tool, it will be slim and large!). But a question is not clear to me (as many other questions, past, present and futur!).

Aircraft spruce list : #9044 at 400 pounds test and 4 of those for a Hazt bi-plane of 1400# gross weight
#1080HD at 900 pounds test and 4 of those for a PA-22 of 1650# gross weight
#1380 at 1160 pounds test and 4 of those for a Pitts S-1,S-1C,S-1S of +/- 1200# gross weight

How calculate I need 12 x 400# shocks cords for a 1600# Rebel? Is it because the design of the landing gear, or just because I should expect "overgross" landing with many "G"... or someone add rings
until the results where goods!
