Duh! It just took me this time to realize you are mentioning problems taking off from grass. Many of these small planes have wheels too small to be effective on grass. If you drive to your flying site, or if you live real close, maybe some sheets of thin plywood or corregated cardboard about 2, 2 1/2' wide and a long as you can fit into a car can be laid out in a semblance of an arc to serve as a temporary runway to let you have a smooth take-off. Just stack one end on top of the nest sheet so that as the plane tracks on TO, it drops onto the next sheet.
