Our field is an all grass runway, actually, it is a full-scale grass runway. We keep it cut pretty well, but it is mainly crab grass and quite bumpy. We roll it out as often as we can, but it still is quite bumpy.

I solo'ed with the Hobbico NexSTAR. I changed the wheels to the 3.5 inch light-weight (foam tires) and it did not affect anything. It made it easier to taxi around and take off and land.
