Thank you all so much for your replies! They are very helpful and have answered my question.
Im not too sure the H&S aspect of sticking airfield cricket in a bag is going to go down too well lol! We have to get them specifically farmed, might be good fun sticking a sweep net on the back of the aircraft and collecting all those in the prop wash!
To be honest i had not considered that the 10 hours gained gliding may be wasted due to the difference in 'feel' etc of a powered aircraft.
I'm also keen to have a go in a microlight such as the Jabiru/Ikarus models as they seem to be a good way forward, being less expensive to fly/attain NPPL but still having the look of a Cessna 150 for example. Does anyone know of a field in Kent that runs lessons with such aircraft?
Thanks again
Ben
