The next thing I want to do to the fuselage is to fit the cabane struts, but I don’t like to put my trust in geometry for this critical job, especially if it’s my geometry!
This means that before I do this I’ll make the top wing centre section, hold it in position with a temporary jig and then fit the cabane struts thus ensuring that the wing incidence etc. is correct.
If I’m fairly confident that what I’ve drawn on the plan will translate into the actual part when built then I usually make a “kit “ of parts.
The 2 outer ribs are 1/16th ply the others 1/16th balsa made using the “sandwich” method and then the inner ribs are shortened to fit the trailing edge cut away.
The hardwood blocks have a hole for the wing location wires drilled at 5º
[ EDIT: information received later suggests that the correct dihedral angle should be 3º 20’. I hope to be able to modify the model accordingly. Information received even later suggested that the dihedral angle was indeed 5º; because of this conflicting information I decided to leave things as I'd first designed] to give the correct dihedral and grooves routed to fit onto the 1/8 x 1/4 spruce spars. The yellow “pegs” are in fact snake inners tapped 2mm that will have grub screws to lock onto the wing wires to hold the wings in place.
The build starts with the trailing edge.
