With the fuselage skinning virtually complete following application of the pieces each side of the tail skid, it’s time to move on to the wing structures before closing up the lower fuselage root areas.
Once the 1/2” x 1/4” spruce main spars have been spliced up/tip ends tapered & the false LE + main spar web pieces joined up, it’s a straightforward task of assembling the majority of the wing structure.
I started by glueing the spar onto the lower front face of the spar web, remembering to have the tapered main spar surface on the inside of the wing & also remembering that the web ends at R28 - not the tip!
Also remember to fit the main spar doubler at the root end of the spar.
Note that the spar web only goes inboard to R6 as individual web sections go between each rib towards the root.
I started at R6, working steadily outboard, adding servo plates, flap linkage pivot plates etc. as I worked outboard.
If a few widely spaced ribs are initially fitted onto the spar web/lower spar + false LE, then subsequent ribs can be dropped in between these two span-wise main members.
I suggest adding the slotted & tabbed flap & aileron LE webs before the full span rear spars are added, as these will locate the rear of most ribs. If you leave this till later, you are likely to find that the rib rear ends are in the wrong place
Anyway, after only a day & a bit, I now have the 1st wing with nearly all of its cut parts & spars.
- Root end view
- Tip end view
- Flap/brake servo areas
- Outer flap/Inner aileron break
The twin brass joiner tubes have also been slid into position.
Note that R1 & R6 are handed for right & left wings as the joiner slot positions are staggered differently in these ribs for each wing.
