Sorry, ad you asked we have also sent you a declaration for your insurance. Unfortunately sometimes happens that you touch something with the propeller and don't notice it, was the propeller the same as when you start or was the propeller broken upon returning? Look at your pictures. Why you have payed for the Damage?our service is perfect because we have the propeller photographed before each rental, make a negative review after having done damage is not a great thing, but anyway we hope you can have your money back with your insurance. we do not glue any propeller! Ciao
