The first sub assembly of parts C, K, M and N can be glued together on the bench before fitting and glueing into the fuselage.
Once the woodwork is aligned I used an old6 volt battery to hold everything in place whilst the glue sets.
I actually cut off the “rib” parts from the bulkheads K and L as I wanted to alter these for mounting the mechanics. This will depend on what time of mechanics your fitting.
Woodwork
Parts G & H held in place with a piece of wood while the glue dries.
Fitting the cockpit floor and strengtheningplates for the flight batteries and mountingpoint for the receiver switch.
