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.
