It is not us who fear the tailwheel, its the insurance companies. Don't
pick on me because I am building an 'A', after all, I respect the
physics that say a trike is more insurable ... er .. I mean stable
I would be willing to bet all of Spikes money that its the same reason tailwheels will flip over. Excessive speed and excessive brakes!! I think your right though, I would expect the nose wheel has to fail somehow for the A to flip. Of corse, you can still "ground loop" a nose wheel if you lock up one wheel and let it turn sharply with enough speed. Gear fails, wing tip hits the ground, over we go!!!
-A models flip over while tailwheel models spin in circles. Maybe the airplanes just want to bite off own their little wheel no matter where it is put.

RV-6A Wings
"If it was easy, everyone would be doing it."
As I stated earlier you need to have proper clearance on wheel pants on all airplanes! You also should stay off of wet slusht runways because the wet slush will turn to ice when you get to freezing tempatures. The only RV-A's that I have heard of having difficulties besides wheel pants bing to tight had a not properly bolted together nose wheel leg. He didn't use the washer's Van specified and over tightened the AN Bolt which broke and allowed the nose wheel gear leg and wheel to rotate 90 degrees or there abouts prior to a landing. Resulting in a ground loop. It was not pretty! I have heard of certified airplanes with nose wheels locking up when not proberly maintened or abused.
Actually, the picture John posted is of a converted Tailwheel Grumman. But they are similar in look to the RV-6.
I realized it wasn't an RV in the picture, but after I followed his link I started searching around on ebay and came across a RV-6A that was damaged in a roll over. I tried to go back and post the link, but the auction ended yesterday.
That was an RV-7A that was listed on e-bay and somehow ended upside down when doing some highspeed taxi tests. No specifics were given other than that. There was considerable damage and I am not sure it was as easy to repair as listed on e-bay. That is one of those things only an RV-7 builder could tell with a personal inspection in my mind.
