Gents,
As the OP, may I thank you all for your comments and I've read them all.
There is a suggestion from a poster, that I may not be getting the best out of my system. Many thanks, I'll follow this up.
There were of course one or two 'keyboard macho warriors' who took the opportunity to insult me. Only if you insult me to my face will I respect you.
This sim so far has provided more than enough to discover,learn and enjoy; even though I can't yet fly at treetop height.
The silent majority don't whine. They recognise potential,effort and determination when they see it.
Sorry for my whine
Best Regards,
MB_Avro.
