Hi Parkfell,
Thanks for your reply. Just to be clear I don't ever intend to instruct on a full time basis or earning a living from it, just part time as a way of staying current without having to pay for flights and helping others get in to the hobby of flying.
Please excuse my ignorance, what's a P1? Glider tugging sounds interesting.
Just to be clear I'm not looking for shortcuts, these things are difficult and time consuming and rightly so.
