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 ?

    @stefan, the aluminium foil (is in fact a thick aluminium tape) is used to shield againt EMI interferences all of the sensitive parts. It is indeed the sonar that you see shielded. Here is another picture for you:


  • Hugues, what have you covered in aluminium foil on the first picture? Is that the sonar?

  • Haha, nice one! Good idea!

    I'll see if I can get a volume rebate if I buy my rubber parts in larger quantities, that should get the price down to 1 dollar :-)

    @Daniel, yes the ball guards are from the heli world. They use it for landing training. For fingers protection though, i am thinking about circling each motor with some material, but i do not know yet what.
  • Ahh nice one Hugues! I've seen the foam used several times, but not in the diagonal position. Unique and probably effective.

    Plus I see you have the pingpong ball guards. I was thinking about doing that too, because we want to keep our fingers.

  • et en France, ils appellent ça des "frites"... 

    in France they call them "fries"

    @Joshua: it is very light. Did not weight it though
