We have 130+ but not all of those fly.
We have a few groups, the day time unemployed and retired, then at weekends you got everyone else, maybe 20-25 flyers at most.
New commers are easy to spot. ( ok not for you if they come from other clubs )
They all have MDS engines, have castor in the fuel and a brand new trainer.
Most of our new flyers come to the field first with no plane, then get interested, so we know who they are to start, or they contact the club officials.
The worrying bit is these people tend to show up when no one who is good enough to buddy box them is about, which leads the the ( just gone solo ) bloke to take them up. You know, the bloke who did it last week and now cant stop flying, the one thats always on the field.
The problem being they might well be able to fly a plane ok, but not one thats out of trim, or regain control quick enough when the newbie gets it wrong.
We do have a club training plane, and it has two trannys, which is good for me as my memory is full on mine. but sometimes the better pilots than me normally pass on the job coz they dont want to stand there and not fly them selves.
I hate it when you say "ok help you fly", then you find a problem, spend ages fixing it, find the next and same again, get them flying, and you've just wasted your flying time.
Whats WORSE!!!!!!! is when your training a 12 year old and showing him how to land, then let him do it and his first try is perfect and makes you look stupid
