Just for the laugh and DIY competition spirit, we saw two recent blog posts about how to do the cheapest as possible landing gear for quads. Here is my formula : estimated cost : less than 2 dollars for four legs using swimming pool foam sausages (i do not know how you call this in english, we say "boudin" in french but American do not eat "boudin" , sausage is the closest I find ;). So here it goes with my recipe:
-One long foam "sausage" , found in any sport's shop for old ladies needing support in swimming pools
-Cut the foam sausage in four equal pieces of length = original 3DR leg + one or two inches
-Cut at 60° the bottom of each piece
-Tie each foam piece with zippies on the 3DR leg
Who can do cheaper ?
