HOW DO YOU CHANGE STALL CHARATERISTIC

How do you change the stall characteristic of a flexwing.
My new wing stalls about 2 inches forward from neutral bar position and has a violent nose drop at the stall. Bar about 4 to 6 inches from profile tube when stall occurs.
Would it help to adjust end cups, and how is it done on a Raptor wing?

Wow coatwise!
You do not have the best of luck with this trike hey!? Is this still the same wing that made the hole in mother earth? Wish I had a answer for you... Did you measure the angle to which the wing banks and pitches? Should not pitch more than 30 degrees. Would say if it touches the profile tube max 35 degrees.
Hope you come right!

You really need to be talking to the manufacturer or a suitably qualified AP for this one

Agree with Morph,
Don't mess with a wings stall unless you know what you are doing.

Hi Karl
No not the same wing, the wing that tried to commit suicide was totally destroyed. New Raptor wing flies like a dream, just the stall position a bit worrying.
Morph I have spoken to Manfred already and he is waiting for some data from me at the moment, but the bloody wind in the Eastern Cape won't piss off long enough for my instructor to fly the Trike and get the exact speed the stall occurs at. When he test flew it Sunday he says the stall was at about 42 to 45mph. Manfred says the stall should be about 35mph, so once I can get the info to him he will probably be able to advise on what to do.
Thanks to everyone for their advise.
