C-I-M.....
I notice from your profile that you are a ppl student (nothing wrong with that) however this is a forum for
instructors 
. No one is forcing you read this topic so with respect I do not see what it has to do with you
The purpose of pprune is for interested parties to air thoughts, opinions and comments about aviation (originally 'professional aviation'). Whilst my own topic on this thread is indeed personal I have made comment for two reasons...1/ to see if I can induce the 'other party' into paying me (I do know he reads Pprune) and 2/ to draw attention to other instructors of the risks involved in dealing with unscrupulous and untrustworthy flying clubs and their owners.
Remember this thread is titled 'Shafting of Instructors'
