Amex,
Hear, Hear - he's obviously a 100hr weekend wonder! oh, and for your info Saveloy the reason we dont paint plastic gliders, is because of vast temperature ranges the aircraft is likely to fly in:
Spain / Africa / USA + 42 degrees @ sea level, and in Scotland, minus - 50 degrees in wave @ 30,000 ft - a height that you will never get to, unless you either fly airliners / biz jets or have the skill to get a glider up that high!
And for the record 90% of the Farmers i have met on land-outs are extremely helpful, pleasant and are always interested in the sport- farmers would prefer gliders to land in their fields rather than Hot Air Balloons, due to the damage caused to crops with the basket dragging.
