I didn't know that "Kavan RC" still exists. But here in the USA they still sell the Kavan RC version of a finger guard for flipping props. The finger guard tends to be sliced up and destroyed fast if you use those razor sharp plastic props though. That was what destroyed mine when I used to use them. The long rubber rails or ribs on the bottom side of the pic is for the back of the finger for when the engine kicks back and the prop blade hits the back of the finger. The little bumps on the top part of the pic is actually the part that makes contact with the prop for flipping.
