TJP - Ditto, mine pitches to the belly in knife edge, as well. I do not see the "float" on landing that you've observed, or certainly not to the extent you describe. One thing that I have not investigated yet... at low speeds, mine is more stable inverted than upright. I suspect an aileron (spoileron) trim problem.

I also upgraded to 4-40 hardware on all the pushrods, as well as the tailwheel assembly, right out of the box. One other weak point IMO, at least if you're flying off asphalt or concrete, is the "rubber" on the mains. Unless you grease every landing, and never skid the plane getting it slowed/turned, they are going to start throwing off big chunks of foam fairly quickly. I observed this and replaced them with the Sullivan "Skylite" wheels. No problems at all with these, probably 20 full stop landings and at least twice as many touch & goes since installation.

CNSASS - I'm not sure, at least in my case, that I would call the wing loading on this plane "light". Mine is pushing 33 oz/sq ft with no fuel. Of course, I moved up to this plane from a .60 Extra (22 oz/sq ft), so I may need recalibration!
