There was a reasonable thread on this a little while back which you can find
here.
The best advice is to give it a try and see if you like it. There is quite a wide range of machinery available in the microlight class from extremely good value (but very slow) older flexwings to extremely expensive (but only a bit slow) 3-axis machines.
There are some flexwing flyers here who may be able to advise on the Medway. I must add flexwings to my list of things to try next year on the other
thread.
You would be far from the only heavy metal flyer on the microlight scene. I was taught to fly microlights by a retired DC10 pilot, given conversion training to my current machine by an Airbus training captain and have a 747 captain friend who flies a Jabiru.
That's not to say they haven't all lost it as well, but at least you needn't feel lonely!
