Magpies + Crows

I had a problem with Gulls attacking the Inspire and after reading loads online about how to deter Gulls, I ended up spraying my fuselage Day Glo Orange which has worked out for me.
Not sure about Magpies & Crows though...

Ive never had any birds bother mine, they all flee, however no crows or magpie encounters yet. use carbon fiber blades and ignore them or establish dominance and chase them and they might leave you alone, they probably wont get close enough to hit it anyway but if they do, sliced salami and unlikely to break the carbon fiber prop, lol!
