The point about this type, and as far as I know all flying flea types, the front wing can and does stall, but all that happens is the nose drops and it installs itself. The rear wing stays unstalled. I'm not sure in the accident it actually stalled. I tried cutting the power with the nose high and the stick back. The nose did drop sharply and we lost a bit of height but it did sort itself out without intervention. It only proves I suppose that somewhere sometime somebody will be a bit of a clot!
I did wonder at the time whether a severe roll upset might be a problem close to the ground as you can only right it by lots of rudder and the subsequent response to the skid.
I'd rather have ailerons!
