    Thanks Pete. We are going through the circuit today looking for any stiffness. There are flettna strips fitted - fairly sure they were as described but I'll check.

    Subject: Cradle for rotating fuselage wanted
    From: "graeme bird" <graeme@gdbmk.co.uk>
    I need a jig to allow me to rotate the fuselage for smoothing/painting. Before I order an engine stand which I will have to modify and store to ever and ever, I wondered if anyone had brought or made one that I could beg/steal/buy? Don Kesterton has made a smart one with a Clarke engine stand and a propshaft universal coupling. I am in Milton keynes and could collect in a trailer. Thanks -------- Graeme Bird Read this topic online here: http://forums.matronics.com/viewtopic.php?p=315190#315190

Graeme, Alex Bowman made a quite simple jig cut from two sheets of 1/2" plywood, suitably reinforced. With a cutout for the fuselage, taken at the firewall, the plywood was cut to become a large wheel, perhaps 6 or 7 feet diameter, which rotated on rollers or castor wheels attached to a plank resting on the floor of his workshop. The tail was raised to level and supported by a cushioned trestle. I have no details, but I believe there was a picture of it in a story published in Sport Aviation several years ago. Alex found it was particularly useful since he was making his own cowl w/ a rather elaborate monowheel fairing...he's told me it worked quite well, as the fuselage could be rotated like a chicken on a rotisserie.

    Thanks for that, interesting, I have drawn up something very similar using 18mm ply and using boat rollers on the board -------- Graeme Bird Read this topic online here: http://forums.matronics.com/viewtopic.php?p=315222#315222

    Paul, Neutral means many things. The Europa aircraft should indicate nearly dead beat return to trimmed speed when the stick is pulsed upward sharply and released. Quickly pull the stick back about one inch at about 90 Kts. (I hold my forearm against my knee and pulse the stick with my fingers) and release.) If the plane corrects back in less than one oscillation cycle that is what is meant by dead beat over here. If the nose basically stops in a climb or very slowly continues up, and the stick does not return exactly where you had it and it does not return to the trimmed speed, you have friction in your pitch system and it must be worked out with lube, or whatever is necessary. If you pulse the stick up and the nose continues up but does come back to trimmed flight after a bit, your stabilator counter weight is a little too heavy (acceleration forces pull the leading edge down). If you pulse the stick back and the correction is quite quick back to trimmed level, your counterweight is too light and the acceleration has pulled the stab trailing edge down causing a nose down pitch. This makes flying in turbulence fatiguing. I suspect you have friction in your system. Please try the following. In the hangar and no wind, push down on the dorsal fin area just forward of the stabs, bouncing the aircraft briskly, and watch your stabilators. Normally they will move a bit as you bounce the aircraft but essentially stay where balanced. If the TE of the stab goes down, the counterweight is too light and vice versa. If the stab doesn't move at all, too much friction. If you move the stick or the trailing edge of the stab, the tail plane should move easily with little or no friction or stickiness. The bearings may still have dirt from finishing in them, or your trim tube could be dragging a bit, and must be clearanced. Vague trim is an indication your Flettner strips are too small and the trim tab can't feel the change in air pressure and transmit that to the stab. It's a start. Hope it is something simple. As for checklists, I was a standardization pilot for years in the military and used to build/update operations manuals, checklists and local procedures manuals for quick reference.. I made a personal checklist for my Europa trigear or mono or glider, equipped with an old 914 or 912 series engine. I plastic coated it for durability and have it as a ringed flip checklist. There have been changes over the years but basically it works OK. Take a look. In my feeble brain, it works to my logic. This is a personal checklist, it is for my use only, I still carry the engine manufacturers operational checklist and the Europa checklist in the aircraft. I do not intentionally deviate from anything in the operators handbooks. Many items are excessively abbreviated and may not suit other pilots. It is my belief that we all should have a personal operators quick reference card that can be accessed quickly, similar to the one produced by Europa, and refer to it often. I fly with this one next to me at all times. An excel spreadsheet is attached. You may use the format if you see fit. As everyone knows, I can't do anything briefly so it is a number of pages...
