I was aware of it thanks to Mike Connors , he also gived me the advice of not to leave soo sharp the outer portion of the leading edge to avoid that.
I left the inner 50% of the leading edge sharp and the other portion ''kind of round''.
Great! That may be your saving grace. I didn't want to be a buzz kill and tell ya after it's all covered, but you got some great advice before hand.
