Hey everyone, it always bothered me when my Quad hit the ground hard, so I started looking on a way to add a suspension to it and after 2 weeks of trying, this is what I came up with:

I got some shock absorbing from a 1/10 scale buggy and added wheels, one on each side of each leg with a total of 8, they are very light (used on some airplanes like Apprentice etc). Had to 3D print some parts to hold the shocks on the Arm, I also printed the Sonar support. I am very happy with the result of the suspension. To test it I cut the power off at about 2 feet high and it hit the ground but it doesn't bounce at all (the shocks absorb all the impact). I'm very satisfied with the results, and I just wanted to share.

yes, looks very strong, did you drill all these holes on the Arm or you can buy them like that?

I drilled my self :-))  Square tube 3/4 or 1/2   from Home Depot

How about this for inspiration.  The pads are light weight and allow for some slippage when landing with lateral velosity and there must be some shocks in there somewhere.  And the gold foil is a nice touch.
