Whilst waiting for some supplies to arrive, I’ve started construction of the 1st (LH) wing.
The first jobs are to splice up the main spars (tapering the outboard 400mm from 1/4” to 1/8” thickness on inside surfaces only), plus joining the main spar web, LE spar & aileron hinge spar web sections.
With the lower main spar pre-glued to the bottom edge of the spar web (Note that the main spar web assembly goes from the tip rib to R5 only, with a separate section going from the inboard side of R5 to the root), the ribs can be inserted into the spar web & registered using LE web & aileron hinge spar.
Note that some ribs need the lower part of the aileron hinge spar tab slot to be removed before they can be fitted.
(I initially fitted the aileron hinge spar in place using just the ribs at each end to hold it in place, then was able to fit the remaining ribs over all 3 spars).
The building tabs on both the webs & a number of the ribs do a good job at making sure everything lines up & a spare bit of strip wood temporarily clipped across the lower surface of the tabbed ribs ensures that the non-tabbed ribs align at the TE.
I’ve initially fitted about half the ribs outboard of R5, plus the aileron servo plate.
