The wing is the thing, and this airplane is all wing. Mud is not a problem here except for in the parking area in front of the house, and the horses cause it by milling around. Mill, mill, mill. The airfoils would not be laminar, so the lift will not change much due to rain, and I wouldn't want to fly when it is rainy anyway. Bugs are rare at this altitude during the day. Grab handles for ground handling is a good idea, as are oversized tires. There is no where to land for a hundred miles except for the flat spot we made with an excavator, so this plane would not be for 'going places' and buying things, it is envisioned as being just to fly around the local area, taking off from and landing in the same place.
