DH164, without any respect I think you have a problem:
If you want to pull yourself over your xxx POINT FOUR! hours in a Moth thats fine by me.
You were merely being asked what qualifications you had to make the statements you made, but what we get back is heavy sarcasm because Arawa clearly has a lot more Tiger Moth expertise/experience than you do.
Or are you embarrassed at the contradiction in your statements about the value of slats in your various postings.
Please take the time to re-read the last two paras of Arawas last post; I happen to agree with these and there's no way they deserve your petty, unhelpful and spiteful response.
