I have a DJI F550 Hexacopter, and I purchased the landing gear for it, and all the legs broke in just a few lightly hard landings.... those legs are way way way too fragile!!
So I decided to do my own DIY landing gear, and I am really happy with what I came up with :)
I went to Home Depot to look for some wooden sticks to make my landing gear, and I looked around and I was in the pipes area, and I found the perfect thing!
I found a Plastic Hose Pipe Splitter with the hole diameter perfectly matching the wooden sticks I found there (7/16 inch). So I purchased 12 pipe splitters (70 cents each), and 2 wooden sticks ($1.30 each).
The wooden sticks are very easy to cut with a cutter just cut a little bit all around the wood, and then just snap it. Very easy to repair the landing gear in the field, or even pre-cut some sticks and bring it with you...
So far, I had harder landings than the ones I had with the original landing gear, and my DIY landing gear still did not break.
What I like the most about this, is that it is easily removable, since the sticks go inside the plastic pipe splitter by force / friction, so there is no need for glue, or screws... easy to remove, easy to repair, also surprisingly light! and best of all... very cheap!
