I built the Tiger 60 kit and the Tiger 2 ARF.
In both cases the plane is quite tail heavy and in both cases, even after balancing with a heavy spinner and some weights, the plane will sit very precariuosly in the trycicle gear... it may drop the tail if hiting a bump while taxing or taking off.
To correct the last I raked the wing mounted mains back something like 1/2". Incidentally, those wing mounted mains are far apart and the landings are made very easy.
If you built the taildragger option it may correct both problems since the mains will be forward and the tailwheel mill probably not add too much weight to the tail end. But then the mains are going to be closer together...
In any case, it flies like a dream...
