Somebody mentioned Nayland......
It's actually in Suffolk, and is remarkably free from undulations, just a steadily increasing upslope until you reach the crest of the hill, where it flattens out for about 150m. Wonderful strip, not for the faint hearted PPL fresh from GFT....
Normal take off is downhill, landings uphill no matter what the windspeed/direction is, but I have launched a Cub into wind from the 150m flat bit at the top.
I've spent the past 10 years trying to work out how a pilot (believed to be 'an instructor'), in a 150hp Super Cub (almost the world's best STOL aeroplane), managed to leave the aircraft in rather a mess in the upwind hedge????
