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.

Like your idea, sure we all had it at some point but only few implemented it! nicely done

now a bit of constructive comments: 

Lose the wheels all together... rotate the legs to the part that is round hit the ground first and it will act like a skid... 

you may need to find the optimal angle and all to make ti fold but this is the same principle as the X1 quads we sell.

Your solution is stronger as the X1 only uses a regular spring so adding a shock is nice.

yes Ellison, this would definitely be lighter, some thing to think about...tks

Veikko, that is a good idea also, just need to find a very light one...

Tooooooooooo Heavy

hummm, not too bad Alex if I fly without the GOPRO i don't even feel any difference, but I want to upgrade my motors and ESCs anyways, I am thinking getting the AXI 2814, what do you think? does it worth investing on the frame or should I get a Droidworks or something like that?

Luiz,

With all gears you have ,maximum recommended take off weight must be 1600gr
Actually total weight frame, motors ,ESC and radio with APM average 1000gr, plus battery 2200Mah 200gr
Total 1300 . You have left 300gr for gimbal and camera.
For training flights I would recommend flights without camera. You don’t need huge landing gears. Landing must be gentle and smooth.
Training training and  training. Don’t rush to spend a lot of money for new gizmo

thanks Alex for you advise, I have this thing in my mind that I am always trying to improve things, I am a designer and when something bother me I want to fix it.....or improve it..., but you are correct I need more training..and training....thanks again

Luiz, your design is Ok, but for all flying objects on first place durability and less weight

Comment by Alex on April 16, 2012 at 7:40pm

My quadro has very strong frame Total weight with camera and gimbal 1485gr
