Attaching the Fin

After a break to prepare a Cyril for the F3B season it's back to the Phase 5.
Next job is to glue to the fin to the fuselage.

When the fin is glued on it has to be jigged up with anything to hand to keep it all straight and true.

The fuselage and fin are both held firmly in position.

Building the Fin

The fin is a hollow structure. The bottom section is made of ply and holds the bellcrank. The rest is balsa.
