Lu Z.
When you started to post on this forum, Helidrvr explained that he'd suggested you did so, that you'd effectively been driven off another Heli Forum by personal abuse, and he'd assured you that you wouldn't get the same treatment on Prune as you had previously. (I think the last part was a gentle hint to Pruners!)
It all seemed very odd. Why would people be abusive to you? I didn't understand it at the time.
Now I do.
Don't you realise that you drive people to distraction?
Your Robinson contributions were interesting at first, but it soon became clear that you had an obsession not only about Robinsons, but even against Frank Robinson personally.
You've even managed to alienate the people who at one time were defending your right to express your views, and asking others to be patient and polite! Helidrvr does his best to keep some sense of decorum. A lady PPL occasionally reminds us that you've increased the volume of posts etc.
But you get on most people's t*ts.
Most of the contributors to this forum have enormous practical experience flying all types of helicopters. Some seem to have fixed-wing experience as well. They've not only flown, but operated civil and military helicopters in many different spheres. There are instructors who, between them, must have trained thousands of pilots, on many different types. Individually and collectively, there is a wealth of talent to be tapped by anyone prepared to learn.
You are spoiling the forum, Lu.
Haven't you noticed that for months people have been asking you to back off?
To let things drop occasionally?
Not to spoil discussions?
Not to try to turn every thread into a Robinson debate?
Suggesting you stopped posting?
There's now even a suggestion that you ought to have a forum of your own where you can waffle on to your heart's content.
I'm not surprised you ended up being subjected to personal abuse on the other Heli Forum. You obviously drove people to distraction there, just as you have here. People start off responding politely, and then, eventually.......
Why not move on to some forum where people discuss theories instead of what actually happens in real life aviation?
Or start/find a forum which discusses your other interest, model aircraft?
You might be happier - it seems like a lot of people here would.
