RE: 35% Giles...
The G202 flies and lands well with the CG about 1/2" to 3/4" in front of the front edge of the wing tube. The manual used to say 1.5" to 2" forward, that was very conservative and difficult to achieve with any engine lighter than a briggs and stratton. I changed it because yje general consensus was that was too conservative.
IF your balance point is no more than 1/2" ahead of the wing tube the plane should just settle in gracefully and set down without bouncing. Maybe try some low bounce tires?
