A 4 day vacation.

  I found out today that there isn't any school on Monday and Tuesday. This is the longest I've ever gone to school and not had an absence. The planes are just about built with one still being assembled. I had a lot of trouble  fiberglassing the wing center joint using the schools epoxy. I think the shelf life is showing up and the 2 to 1 mix isn't strong enough to cure it. I mixed another sample 1 to 1 and it cured. By then I had fixed the stuff with another type of epoxy they had. Mounting the servos as shown on the plans is going to be a problem as the screws needed are 1/16 in diameter. Last years  builders used the servo arm hold down screws to hold the servos down. One of the teachers mentioned using two sided tape but I didn't think that would hold. Then I remembered that the servos in the Sig Kobra were held in with two sided foam tape. That will solve a big problem. The money for the covering and stuff has been approved and we should be getting the stuff in a week or so.
  I have the Stuka framed up. I'm using an OS .25 and the plans show a Brodak .25 which is 3/8 shorter than the OS. I didn't figure that out until this morning. That brings the engine real close to the fuel tank outlets and running the fuel lines will be a problem. I bought the kit at the Brodak flyin in June. I still haven't come up with a scheme for the scratch built plane yet.
