Seadancers are pretty docile airplanes and should not tip-stall.

I suggest you examine the leading edge of the wing. If your leading edge is not correctly profiled, you are asking for problems.

Make a card-stock template by tracing the plans, and see how close your leading edge shape is to the printed shape.

Previous post advising you to add washout is also a good suggestion. First check to see that your wing is rigged per the plans. I usually get 8-10 feet behind the plane and sight -check to see if there is any washout/washin. If you have trouble with that, attach sticks to the bottom of the aing with rubber bands, (one at teh root and one at the tip), then sight down the wing to see if the sticks are parallel. Correct everything to the as-designed shape first, then if there is still a problem you can twist in a little washout.
