    Beware of going low. Don't practice to below 200 ft till you are VERY good at it. It requires very good control of Airspeed by precise pitch management. The controls are very crossed up .The Rate of descent is much higher. Recovery to the flare has to be very controlled and precise. Many people who think they are sideslipping are Just doing an ugly SKID. I've often asked pupils and other instructors to do one for ME and MOST FAIL dismally in doing it Properly. IF you have flaps or a very draggy plane you don't need to do it. The Wing must go down first and you stop the Nose falling with rudder. The correct speed should be low but safe. HIGHER SPEEDS stress the Plane. This requires LOTS of Practice to get right, and you won't get it right IF you are NOT taught it Correctly. Practice at Height till you are real good or you will hurt someone. Nev

    Such things MISSING won't do it any good. It cannot be Designed for that. Nev

    It does have two separate Parts and some studs have snapped and there's only 4 per cyl. Nev

    Alumiprep and allodine are the two treatments. Leaves it looking slightly yellowish. I got them from Aviall. Nev

    Not often will that have much relevance to how WE fly. OAT would be Below minus 60 C. I don't know how the Oil or coolant would cope. Nev

    The primer should probably be an etch or use some other al preparation for aircraft. I would NOT recommend any soft surfacer that must be sanded. I'll look up a couple I still have some of Here, later today. Nev

    Isopropanol is an ALCOHOL and won't mix with Wax, Petrol or oils other than Castor. It's a solvent for shellac. But that's not much help. Nev

    Why paint ALL of the surface IF it's alclad? Nev

    Head gaskets are the Weakness/Failure spot in Many Motors. Bolts etc compromise Port size, position and shape. . Nev

    Why chance things? It's an aeroplane. Nev

    The Merlin has no head gaskets. Each Bank has the cylinders and heads made in one piece and held to the case by long studs. Nev

    Hard to do valve seat Inserts Bugatti's are similar. Nev

    Genthin thinners will do. I think it has acetone in it. Nev

    POP Rivets are a bit crap anyhow but have to be used in some Places, because of lack of accessibility on the inside. Nev

    You'll NEVER GET it Turbs. Planes are Not race cars. Nev

    You're over thinking it. Under laws of STRICT LIABILITY the whole scene is farcical. Nev
  19. facthunter
    It's to Better cope with the reality of the situation you operate Under where LIABILITY is HIGH. This is CASA's responsibility to Manage, Ultimately. THEY have the Ultimate say. You can't deny that. Nev

    For an Engine well before it's time, Look up 1914 Delage Four valve desmo Racer, One of three still left. I knew it before the Block had to be replaced. It was worked on By Jack Nelson at Romsey, A very good friend of mine and IT was a " Runner" for quite a while being entered at the Geelong sprints several times. The replacement block complete with Head was done At Malden involving "Up the CREEK Motors" which specialised in Austin 7 s. THAT CAR is Priceless. Another NICE motor was MILLER a racing speedboat Motor which was the BASIS of the OFFENHAUSER race car engines, later. US made. Superb quality. Late 20 and up to Post war. I had the Privilege to work on one in the 50's. It's well worth looking this up. Nev

    The engine never had a TBO above 650 Hour's and only a Very few countries allowed it on the CIVIL register for RPT. Nev

    . The whole set up is not very impressive, Valves are near Vertical . The shafts each side are for the Rocker Pivots. Apparently the Hydroplane Boys blew up Lot's of them. There's a piece been out of the end of that head casting for a while too. Nev

    Stop fires before they become BIG. Usually started by lightning in remote Mountain areas. Nev

    Runs and dust are the problem. Paint is also heavy. Keep the thickness to a minimum. Thick Paint chips. Something like acrylic Lacquer is easy to touch up. If you can rotate the fuselage it would help. Don't spray on cold days. Keep everything clean and have no water in the airlines. Have clean guns and no blobs in the Paint. If paint has fully dried you have to light sand before the next coat. The lights I use warm up the surface. Wear a proper mask. Nev

    Just Pour boost into them . Four valve Head and overhead cams. Lot's of engines these days use roller cam followers. Most American bikes since about 1913 Speedway JAPs since 1932. Nev
