I bought a simple flexwing a couple of years ago but couldn't find any local instructor. I made the daft decision to teach myself and whilst I had a lot of fun, and flew around the farm ok, a couple of rather heavy landings made me decide to sell before I killed myself
One day I'll get some proper tuition and get another one. the whole excersise cost nothing ... but could have been a whole lot more expensive
Such machines often sell for less than £1000 and (if you know how to fly them) represent the cheapest fun available IMHO.
