Thanks for the reply. Although the rules are probably very obvious, being very new to aviation, I havn't come across them yet and this question has been bugging me regarding the definition of 'gain' in the licence regulations. It's also nice to see a FI who doesn't 'ignore the idiot with the stupid question' - thank you. (No serious offence intended to those who didn't bother replying) <img src="tongue.gif" border="0">
Regarding "showing-off", I think you understood what I really meant. Certainly not in my case, but I know it is common, for parents to finance a PPL and it must be common in this situation to show the appreciation of his/her financial backers by taking them on a "thankyou" flight. I didn't mean engaging in amateur aerobatics/hotdogging round the skies.
