These will breakaway in the event of a hard land. That is a good thing, they are much longer with the graphite 7mm x 150mm rods and are much much lighter. I just had a hard land due to a battery and lost 1 leg, recovered, put it back down and broke 2 more of them. Nice thing is that you can print another set of legs in 30 mins, and reuse the broken leg mount as feet. :)
The angle I printed them give it a wide footprint, so the gimbal does not see them as often too.

Here is a picture with the above legs, with both ends setup as backup legs and weigh 12.6g
I just made another version that I still need to test
