Welcome to the free world, you will find many people here are able to say things that possibly you and your country men (and women) are unable to say freely(from what we read and hear) but you will very rarely ever be sworn at, or cursed or belittled in any way that constitutes Bullying, the Pprune Mods are very good in the way they monitor these threads, but more than that, WE the Pprune members will see nastyness and bullying on a thread, and very quickly will make any person responsible feel very small indeed.
There are some very good people who will answer nearly any question you care to ask on almost any subject connected with Helicopters, I am only a Private pilot able to fly helicopters, but I have read and learnt many things that have enhansed my awarness of mainly safe practices in flying on this forum.
Post with impunity, fear no man, these great pro flyers on this thread will help you, and indeed listen to your added information!
