No aeros.....?????
Whats is the point of flying them straight and level. Its just a noisy Cessna unless you go inverted.
Try Gennady at Worlverhampton International World Spaceport for conversions/ trial lessons.
I guess the issue is its hard to get a cofa on them so there aren't that many that are for hire.
You could always approach a group with a view to buying a share.Lots of them available, I recall one at Popham for £2500 share (bargain)
