My wings have been in the 150° to 155° on the leading edge, granted this wing is less angle, here's the data
Reduced drag across the whole wing.
Reduced tip stalling even further than the original
increased Lift to drag ratio. The Wing (starts) stall at 9-11* AoA at 240 mph, and approx 11-14* at 180mph. Meaning it is a crank and bank machine....
PS: Its a wing and a fin only nothing else to drag around
