Rip, I've personally flown a 1C around in big lazy circles with half a wing(or in other words visually half a wing actually the tip shot off, no aileron) left and got kills. Trick is to not get shot down first. It flies quite well, or better than I think it should, with the wingtip gone, like the P38 used to, but now the 38 is a handfull with a tip gone. I have also seen people flying around still getting kills in this 'configuration'.
I may not be able to shoot you down, but someone who shot my tip off, and thought I disengaged because I was having a hard time just flying, might ignore me and concentrate on that other con or 20 about to jump his ass, only to have that same wingtipless 1C(me

)come back and shoot him down. I've personally done this.
While you might simply call this dweebish behavior, and I agree, I think anyone missing the aileron and wingtip should have his hands full and be thinking about nothing else other than suriving. But that's my opinion, I don't have any data to back up my theory.
