When we were designing the Phantom Rain Wet Suits for the Phantom we considered adding these to increase the strength of the props so if we got into a tangle of some branches , the props would not pop right off , but rather it would back the drone off and allow it to continue flying.
With that said the problem we had was that the inside of the Props were Plastic and the tabs that are inside of the Props were so fragile that you can pry them off with just your finger nail.
See Picture below as to how thin these clips that hold the props on really are.
So these base Aluminum plates were not the answer to locking in the props so we designed the Prop Covers that added a very thin layer of neoprene to the inside of the Prop itself to strengthen the bond of the inside of the prop locking it on tighter and stopping the rain water from getting inside of the drone.
This proved to be very beneficial in many ways. The first being that we did not have to worry about the props wearing and flying off . Second that we could get thu so tough areas to fly, branches and twigs and such without the worry of them just popping off.
But nothing stopped the blades from cracking when they came to a rock and hard place and we were finewith that.
Below you can see a picture of the inside of the Prop itself and how weak the clips are , how thin they are , and how they give away very easily.
You can also see in the other picture the Prop Cover and how it sinks inside of the prop cover giving it a really good lock while protecting the integrity of the motor and the drone.
We wanted every chance to get the drone back to safety , and if by chance the drone motor gets damaged that is better than the drone crashing into the ground because it lost a prop hitting a tree.
The rings on the bottom provide a roof for the water to drip off of and over the drone while keeping the vent open at
the bottom.
The other weak link on the drone are the Leg Clips and we have seen many posting how they fall off and so the Leg Wraps were designed to keep the clips on tight by wrapping and them and providing water protection to the electronics inside.
