I found that transitioning from PA-28 to Remos GX and FD CTLS was a complete non-issue and I just cannot fathom how people flying basic singles manage to have a problem with it, even crash. Coming down from a 757, I can understand a problem. But GX and CTLS fly pretty much like the 150, only better: controls are more responsive, there's a good authority at low speeds, loss of speed at the back of the power curve is actually less severe than in 150 with 40 degrees flaps. I think my only issue with them was that cowls are oddly shaped and featureless, so I had to use an internal reference to avoid landing sideways (in CTLS it's the plane right between the rudder pedals). I am sure it's a problem of complacency, not skill.
Transitioning into Carlson was a big deal for me, I even had a landing accident before I became used to its handling. But a plastic-fantastic LSA? I don't think it's problematic. Should take a minimal amount of respect for the airplane and 2 or 3 landings with a CFI at the most.
