Hi
I am looking to build a trike unit for a microlight aircraft as in the photo.
but using CF tubes in place of the aluminium tubes.
Some tubes needs to be rigid with good tensile and compressive strength but with little or no flexibility.
The pair of undercarriage legs, 1 meter each, need to flex about 3 to 4 inches when landing.
Total weight including pilot is 170 kg.
Recommendations please on the type of CF tubes by Easy Composites.
Also is there a website or calculator to figure out how much a particular type of tube will flex for a given load?
Thanks!

0°, as you are bending the tube.
