Thanks again guys, prop issue was a few months ago and a new prop has been fitted, not sure about shock loading etc tho!
Just need to sort alt issue out at this time, the guy running the group is putting up his share for sale, but has cried wolf before, we'll see if he goes this time!
The reigns have been passed over to another "in his fold" so we'll see if I get more joy out of him, but I feel that he will still have an influence using the new front man as a "puppet" while he is still in the group and not so sure how detached he will be if he leaves.....
Any info on light aircraft max permisible alt error on ground is still what I'm after if anybody has concrete figures on paper, which I can be directed.
Thanks for the word of caution nutloose, trying not to give too much info awaya and too many details and thanks for lycoming docsd too.
