Hey everyone, it always bothered me when my Quad hit the ground hard

 

Heh-heh. My co-hobbyists call these "Navy landings"... I'm a pro at them.  ;)

Very nice solution! Very rugged.

Nice.  Love to see some video of it in action.

Cool! How much weight do they add?

Comment by Luiz Miranda on April 15, 2012 at 7:38pm

Luis, can you give me the dimensions of your quad?. what props are you using? I have some identical motors and want to take your experience. Thanks

I like your design a lot.  Did you find some light weight shocks?  Or modify them for lightness?  How expensive was everything?  What is the size and weight of your quad?  I think somebody could sell a kit like this. 

 

The picture is of a crazy large prototype nose gear I built also using 1/10 scale shock (from a slash) it was going to go on a large drone.

Hi skyracer, my Quad is the 3DR bought the kit here at DIY Store, as far as dimension I measured 24" from center of the motors on diagonal, I have project that I downloaded, if you want it I can email to you. For my props, I use the 12x4.5 made in Germany, found it to be much better and more resistant also, I buy them from this website (http://www.innov8tivedesigns.com/product_info.php?products_id=994)

John, I used a stock shock (19g each) , the wheels are only 3g each, as far as price, I spent about $50.00 because I had to buy 4 rear (Apprentice) suspension to get the wheels etc, If we can find the source to buy just the wheels I am sure it would be lot cheaper. I did not weight the entire Quad, but the suspension only added about 100-120grams.

Like your design too, looks really good

I think the 100 grams is a little too high., though It's almost the weight of a GoPro camera.

Maybe you should use wheels made specifically for aircraft, like this:
