    --> Tailwind-List message posted by: "William Bernard" <billbernard@worldnet.att.net> Guido, et al: I'm not jim C, but I'll offer my comments. The fuel valve will probably work as a simple on/off valve. Use the 3/8" size. A fuel pump is not needed to feed from the main tank to the carburetor. If you are using fuel injection, this pump won't put out enough pressure. For transferring fuel from an auxillary tank to the main tank, it is fine, but I would suggest the FP-40108 since it has the connections for flared fittings built in. The choice of static port depends on the type of tubing you plan to connect to it. If you plan on a tygon-type tubing and barbed fittings, the BP40-FL would be convenient. If you are going to use nylon or aluminum and need to use threaded fittings, I would choose the other style. I used a raised static port that was salvaged from a Cessna 150. Hope this helps.

    Subject: Stub spar
    TailwindForum <TailwindForum@yahoogroups.com> --> Tailwind-List message posted by: Brian Alley <n320wt@yahoo.com> I welded in the H-stab stub spar today, man what a job. After everything cooled, I measured the angles and found that the right side was turned up 1.5 deg. Has anyone else had this much misalignment? Is this something I can heat and bend back into level? I used the 1.00X.049 tube inside the 1.125 tube and ovaled both in the vise. The tube was straight before I welded it into the fuselage.
