    Subject: EUROPA 25 YEAR CELEBRATIONS AT TURWESTON UK
    From: "willydewey" <willydewey@gmail.com>
    I should like to give thanks to all the organisers of this well attended 2 day event at Turweston in the heart of England We were blessed by a large anticyclone centered over the uk and gave unbroken sunshine, warmth and light winds contrary to recent time where events had to be abandoned due to bad weather.. That said I am sure that all Members will give thanks to Ivan Shaw for his witty and revealing lecture on the cicumstances in his life that led up to the concenception of the Europa and for an insight of all the various individuls who helped along the way. God bless them all!! I think there were 42 aircraft at Turweston mostly from the UK but others from France and the Netherlands. The Dinner wes superb thanks to the staff at Turweston but also to Irene Watson the half builder of my G-IANI (ian and Irene) Last but not least thank you to the many friends I made at the event and for the help I received from the head wound I sustained by my stupidity of walking in to the propeller just before dinner -------- Give a wise man knowledge and he will be yet wiser Read this topic online here: http://forums.matronics.com/viewtopic.php?p=481179#481179

    Yes guys this is the time to do it in the northern hemisphere Mine work well enough but were supplied with screws that have a tapered, angled shank., this put undue pressure on the cent and caused starring on the vent which I find unacceptable.. Better to substitute straight screws with no taper on the shank -------- Give a wise man knowledge and he will be yet wiser Read this topic online here: http://forums.matronics.com/viewtopic.php?p=481180#481180

    Thanks for all the responses...I conclude that 1450 is perfectly doable.
