Humbrol Tiger Moth

[Piecost]

Ribs cut out from reasonably light balsa. Those at the interplane strut locations, four on the top left, are from denser wood and have lighter 1/16" balsa doublers on each side. It is poor structural design since the doublers terminate just short of the trailing edge. They would look less structurally egregious if from 1/32", but the kit did not employ this wood thickness.

Since they they did not prove to be a weak spot on the original model: I have kept them.

The cabine struts are shown slotted into their ribs. I have departed from the plan and made them and the interplane struts from bass. I had a nightmare when repairing the original model in picking broken balsa struts from their rib sockets, so do not want the parts to be easily damaged. I will glue the struts sparingly with balsa cement, so they can be dismantled with thinners if repairs are needed.

I will next tidy up the spar slots and
stack all the ribs together and sand them to a consistent profile.
