Flew into East Fortune a few years ago. It may have all changed butThe microlight strip was very short, but on the other side of the road there was a racetrack which had a good long run.
We fuelled up, then hopped one up across the road to the racetrack ( we had asked permission) and then loaded passengers and then took off from the race track. Went round the first chicane at about 20 knots before giving it full throttle!.
The only time Ive ever flown around a race track!
