One thing you could to is take off the landing gear and hand launching and belly landing. This lightens the plane, reduces drag in the air, and the wheels won't get caught in the grass on landing. It also looks better in the air with no landing gear. If you do go this route, I suggest having a friend hand launch it for you the first time. Just give it a good stiff throw directly into the wind, throw the plane straight out, not up. Then after it picks up some speed, you can do a climbout and fly as normal. Then the landing is pretty much the same, just come in a couple of inches lower and set your belly down right to the ground.
