Of course not, thats why I am on here!
by the way Chuck did you check out the fatal at humberside. it sadly lends some weight to my point that its one thing to talk about single engine performance and entirely different doing it near the ground for real!
ps have you seen the size of the stall strips on a aa5 traveller there are 2 and there the total length of an aileron!

Thanks very much djpil - that website has some excellent diagrams. Yes, it seems that the stall strip on the Warrior would ensure that the stall progresses steadily from root to tip instead of jumping root --> tip --> midspan. I might use those diagrams in future. 
Many pilots over-simplify stall strips by stating that they cause the wing root to stall before the tip. However, a more correct explanation: "They are designed to modify the stall characteristics of an airplane by inducing a stall at a controlled location along the wing.” (NTSB Safety Recommendation A-97-41 through -45) leads to questions that aerodynamicists are best equipped to answer!
Seems a shame that the aircraft manufacturers are unwilling to assist flight instructors with actual data for their aeroplanes...
Thanks again,

stall strips or more correctly leading edge spoilers encourage stall at the root before the tip, isnt that what i have been saying all along.
so now we have got some agreement on that, perhaps we can agree that washout allows aileron control at the stall in some a/c in some stall configs. and encourages the root to stall before the tip.
that only leaves slots and slats!!!
