Here is my Bixler 2 FPV HomeMade Landing gear with Shock absorbers
It's made from some "hair elastics" and "metal gas lines".
I cut a "slot" in the Gas line to hold all elastics.
I used some rods from bicycle tires. They are very strong.
I also used plastic Bic stylos.
The tires are from another Plane.
Look at the video, it's easier to understand...
