    --> Europa-List message posted by: "Jos Okhuijsen" <josok-e@ukolo.fi> Thanks for all the good advice everybody. Reminds me of the old saying that there are so many standards, that you can always choose a suitable one. Josok is short for Jos Okhuijsen, which would have been clear if not somewhere the signature between the europaowners forum and Matt's list was amputated. Steve, can we do something about that? Do not archive Jos Okhuijsen

Steve, can we do something about that? The amputation was necessary to save the patient. Signatures can contain HTML, BBCode, Smlies, photos, animated gifs, and other coding nightmares that would make Matronics rightfully reject the posting. I'll see if I can scrub them out..... "ah what a tangled web we weave when first we practice php" I think thats the way it goes... : ) Steved. Do not archive ---------------- Visit EuropaOwnersForum http://www.europaowners.org/

The Mark 4 Harvard (plus the T -6G model) had the tailwheel swivel slanted somewhat forward at the bottom! I asked why as we transitted to the machine, and the Big Boss said it made it easier to land because the tailwheel became self-steering and fought the tendency to groundloop early into the touchdown and stoogents had less trouble with it. It was restricted in this travel each side. I concur it worked, but the apparent relaxation from primal fear was the undoing of some. One can see both sides of the topic............ Cheers, ferg

    Subject: TailWheel Mod
    --> Europa-List message posted by: DuaneFamly@aol.com Good day all, I just came in from my shop to ask about the length of the pushrod from the bellcrank to the rudder. In my instructions of Grahams tailwheel mod, the pushrod is stated to be in the neighborhood of 21 1/2 inches in length. With my rudder temporarily mounted and the pushrod temporarily connected to the bellcrank, both rod ends in the center of their adjustment, rudder pedals at the middle of their range, I am measuring only about 19 inches in total length bolt center to bolt center on the rod. This seems to me to be too short. Before I trim the rod or tear everything apart and start over, I was wondering what others came up with in real life?
