I don't claim to be an expert , but IMHO it seems pretty silly to expect a plane to recover from a stall with half the lift [ one wing stalled ] It seems to me setting two wings at different angles of incidence just increaces drag .
The little Pitts I had had demonstrated no unexpected characteristics with both wings set the same . Sure ,
it would snap with too much elevator input at too high a speed , just a matter of flying it properly . Interestingly , after a few dead sticks where I was afraid of using too much elevator and it came down like the space shuttle I discovered that I could input nearly full up [ while dead stick ] to get some semblance to a decent glide .
I doubt those of you who think different angles are the way to go will change their minds . Dave Patrick uses the same angle for both wings .
Have fun
