You rather fly for free n piss a few people of in Pprune than be a flight instructor when you don't really want to be one .. The worst thing you could do is be one of those sitting right hand seat n stare at the VDO n airswitch and wait for it to tick over.... And instructing is not the easy way to built hours ... As a junior grade 3 an effects of control lesson should take 45-50 mins long brief then 10 mins preflight demonstration then n hour flight followed by a de brief going through training record with student and providing him with study notes for next lesson. So you should be doing only 40 odd hours in a month ..... Or you could head to kunns wait a few months drinking beer and pump out 80 hrs a month Insted .... Ps you can't really say you are not keen on instructing and expect people to say go for it !
