Canberra just went into COVID lockdown today, so I guess I’ll have some time to work on the wings.
Good thing I measured the shed out right. I’ve got some vehicle dollys coming. If I push the Viper to one side and mount a wing, I have a foot of clearance to get around it and fit it before removing it to do the opposite side. As long as my fat covid lockdown guts doesn’t expand, I’ll be fine to squeeze past.
Right now I am just using cardboard to work it all out. The cannons are not terribly heavy, but they are mounted on the wing tips, causing a bit of a cantilever effect. I will be using a steel strut welded to two mounting points in the side of the nacelle, that will support the longitudinal length of the wing, plus the cannon. In the series set prop, there was a sneaky little strut poking out of the cockpit fuselage, attached to the side of the gun, giving it one more support point forward of the wing roots.
Once that’s all measured and cut, I will then build the wings out of polystyrene, with two steel poles inside, radiating from the wing roots to the outer edge. Shape, sand and fibreglass with the rest of the hull.
The rounds are 30mm, similar to the A10 Warthog’s gun. These are turned out of wood, painted and I made the link a couple of years ago out of sheetmetal. I have a plan later to have a transparent or cutaway section on one wing so you can see the load-out of the link to the side of the cannon. More on that down the track.

More work on the wing.
I’ve welded up two wing frames, using the cardboard template as a guide. After welding two solid brackets to the inside edge of the port side wing, I have fitted it to the corresponding arm that protrudes from within the nacelle.
Now that it is solid and set at the right angle, I have press-fit the first layer of polystyrene, then using expanding foam adhesive, glued on the second layer, locking it all together around the frame.
The sanding and shaping has started, however i have run out of glue, so I moved onto fitting the cannon.
