The club that I belong to has a grass flying field. While it is cut once a week, if you go flying the day before grass cutting day, the grass can be thick; great for nose overs on takeoff. So for a long time I have been putting larger than normal wheels on my models. It all started years ago when I bought my first Multiplex FunCub, which came with Tundra Tires. Never have a problem flying off grass no matter how thick or deep with those wheels. So I continue to use larger wheels even on my foam board planes. When I take the Speedster in to a club meeting for Show & Tell, it will have the wheel pants option. But when I go to the field flying it will have the larger wheels.
