Does anyone that is flying have any views regarding the fitment of stall
strips. We were initially advised that these were a bad idea and that an
electric stall warner was a better option. From what I remember, stall
strips are supposed to have an adverse effect on the landing characteristics
of the aircraft.
We just recently completed our annual test flight and were a little
concerned that the aircraft has a habit of stalling left-wing down. With
the flaps up this is fairly benign, but with the flaps down is fairly
dramatic. The wing drops are easily recovered using standard techniques but
it would be nicer if we could eliminate this problem somehow. I discussed
this with several people last year and they were of the opinion that the
wing drop could be caused by the aircraft being out of balance prior to the
stall, however we tried repeated stalls with everything in balance and there
is still a significant drop to the left.
Has anyone attempted to eliminate a dropped wing by playing around with the
positioning of the stall strips and if so how successful was this. For the
time being we are relying on an electric stall warner which is excellent and
we are very happy with it but it would still be nice if we could get the
wings to stall in a more symmetrical manner, not that we intend to make
habit of stalling the aircraft.
Also what effect do stall strips have on landing/ takeoff performance.

PS: If you fitted stall strips, how close to the factory reccomendations did
you end up. The book says about 12ins outboard of the fuselage and slightly
below the centreline of the leading edge (as per the template).
