I have 2 conventional geared KR2's, on both the landing gear is attached to the front of the spar. With the seats empty and the front tank full they are very light on the tail and it is easy to tip them onto the nose especially if the plane is level. Once 1 or both seats are filled and the tail is on the ground there is a lot more weight on the tail.
The attachment point can be seen on the photo below: http://www.rudix.site/ZU-AMV/dsc_9518_std.jpg Fly safe, Rudi
