No, I wouldn't and to be honest you would be hard pressed finding someone who thinks the T-6 Texan was closer to a WWI aircraft in design than it is to a Spitfire, Me109 or Hurricane. Even despite this fact, a taildragger is a taildragger is a taildragger and they ALL have a tendancy to ground loop due to the reason I pointed out about centre of gravity being behind the main wheels. As Scotty was fond of pointing out in Star Trek, "Ya cannae change the laws of physics", unless you are in CoD then anything goes I suppose.
It was the 'physics' aspect of the design to which I was referring. The wheels on the biplane in that video are in front of the wing, much further forward than the 3 planes I refered to in my post, the Spitfire, Me109 and Hurricane, which have the main wheels directly under the wings. Therefore the distance between the 'pivot point'(the wheels) and the centre of gravity is shorter, making the tendency of the aircraft in question to groundloop less. Your other points I do not dispute Mariocart though! Come on its not that bad.....
