1973 Bellanca Citabria 7GCBC

Living the dream. Gonna do the big tire bush thing. Beaches, gravel bars and backcountry strips. I wanted that tandem seating and a proper stick with the throttle in the left hand like my Pitts.

The 7GCBC has the larger 160hp motor and flaps. Still in current production by American Champion, so good factory support.

Baggage compartment had failing vinyl interior that was no longer protecting outside fabric.  Redid the right side in  .025 aluminum, just 'cause I had some around.  Overkill, left was done with .016.

Finally addressed the tailwheel shimmy.  Tailwheel pivot post inclination was -6 degrees instead of +6.  Bought a new fabricka pad and aluminum shim from ACAto put under the U-collar.  Re-arched the spring somewhat.  Over the years that spring probably gets pounded flatter, now on spec.
