I used to fly at a small strip behind a flood control dam in the foothills above L.A. It was 350 feet by 40 feet (about). The departure end rolled out into a boulder lined flood channel. There was a 30 foot obstacle 150 feet from the approach end. (At first, a telephone line. Replaced by an elevated road way when the developers came in [Anyone intersted in an overpriced home built on a fill out over a flood basin?].)

A couple of guys used to fly 35 percent IMAC planes from it until encroaching development forced the club to impose a size limit, or loose the field.

IMHO, the ability to land a model plane on a 25 foot wide strip in the minimum distance should be a performance goal of all r/c fliers, even the most casual sport fliers.

I currently fly of a road to nowhere I found out in the desert. It is 25 feet wide and the length is virtualy unlimited. The heaviest (almost only) traffic on it is Friday night when the local high school students go to party at the end of it.
