Hard landings with my 3DR quad always puts it firmly 3 inches into the ground, splitting the legs up and destroying the nylon spacers.

I created these very simple bumpers so i don't have to dig up my quad anymore:

They are made from pipe insulation and a wooden hub from a broomstick i had laying around.

I cut up the stick in four 18 mm pieces to replace the nylon spacers and drilled a 3 mm hole in the center.

CA glued the hub to the middle of the foam piece and cut openings for the two legs.

Finally i replaced the two short 3 mm screws with a longer one that goes through both legs and the hub, securing it with a locknut.

Very clever! There have been a few discussions about the legs over the months.

Your solution is cheap and effective. A+

Very good solution!  Simple, lightweight and cheap!!

BTW where did you get the red arms from?

in texas we use mud tires XD no this was a very smart idea, it would be wise to think of different situations that can occur because of our landing spot. mud is one of many things.

Very nice solution, give the legs less "biting power" on surface too! I like it a lot! 

BTW I sell the red arms (but for legacy 3DR frames using 28cm arms compared to the new ones 24cm) 

RED replacement Arms
