I thought they might be cast alloy plastic dippedHey, how precisely do you need to know that? If I estimate I would say its ABS oder a similar kind of plastic material.
Yes I see now , so do they bend at all or ust prune to snapping, why I ask is a friend of mine was using his drone to get a throw line around a tree then it got hooked up , it fell about 5 meters and landed on a single arm he thinks its bent is that possible ?Here on this post from an unlucky pilot you can see that they are made of plastic material.
