I'd be careful, I became a CI and thoroughly enjoyed my one evening a week teaching RAF and aviation history, theory of flight, and map reading. However the CO pushed me for an increased commitment which I was unwilling to commit to. I wanted to take the youngsters out on navex's but to do this the CO insisted I attend a Wing induction programme which covered a number of weekends. I opted not to do this and consequently became little more than a classroom assistant overseeing practical exercises set by others.
It's a noble thing to give a little back but it's difficult to give solely on your own terms.
