Tas:
I'm working part time in Ireland as an instructor getting a per hour flown wage and damn lucky to be doing so. I got the weekend gig which means that if the weather is bad (which Ireland wouldn't be unknown for) I get no flying.
Instructing's main disadvantage: Signing students off, you'll soon realise you need balls of steel to do it, one mistake by them could mean your license.
On the bright side, I got my instructors rating a few months back and I have nearly 400hrs already. If you can get a full time job doing it-do it, think about the money later (don't go to the pub)
See ya,
Pan
