    Default Vertical Stabilizer & Rudder Ribs alignment

    I've got the ribs setup on the vertical stabilizer and rudder. There's no clear instructions on the ballpark spacing between them before bonding and adding the fiberglass fairings. I guess I can test fit and figure it out but want to know what you guys have been doing.

    Spacing was in my builder's manual. You might want to check again in yours. Harlan

    Yes, there's vertical separation between the ribs.
    I'm refering to the distance from the vertical stabilizer rib's trailing edges to the rudder rib's leading edges.

    Ok I understand. You will adjust that after you put the fiberglass on with the hardware that attaches the two together, but final adjustment will be after you put covering and paint on to know the thickness to adjust to.
    You want them as close as you can and have them still operate freely. Harlan

    Got it, thanks! great vids on YT by the way. You've saved me many hours of research, build time, and provably hundreds of $$ on avoiding mistakes.
