RE: Tip stalls..... any fixes?
What is so hard to swallow about DICKs' advice? If this plane was built light enough, [inspite of it's inherent design flaws that don't scale down well], the low speed handling problems go away. All the other "fixes" are gimmicks that only postpone the inevitable. On this .40 sized model, the outer 15% of each wing panel is just going along for the ride at landing approach speed, and at the weight it is being asked to carry.
