Temptation

[Wayne Galligan]

After all this discussion about the material in this type of lay-up I just had to chime in.    I think the guys at AeroSlave have got it nailed then.  The use of coremat as part of the composite lay-up seems to have been a good choice of materials.   Everything I have glued into my two airplanes is glued with C/A except for the landing gear plate(epoxy)  This stuff takes to C/A like a duck to water.  When used with C/fiber or glass it proves to be a very stiff lay-up.   Their new Symphony that has a huge fuse cross section shows the advantages of using this material.   In my Aries I have no formers its that stiff(using the c/fiber layup).   
NO I am not sponsored..... but I am an indentured servant.

   Be real careful with anything you glue to the inside of the fuse. We have had many an experience with things falling off. Bobby almost crashed once when his wing adjuster came unsecured in flight. I've gotten into the habit of throwing a little CF chop around the critical spots like that to secure them better. Mike

    I just remembered some advive from Charles Williams
    when gluing parts in the fuselage . . . the fuselage
    construction is chemically compatible with CA, but the
    heat generated when it kicks can melt the foam
    slightly and cause a dimple.
