2 MosquitoBite Planes Robin
Installing Ribs
Place Main Spar upside down on its top edge. Along side it, place
a
3
⁄8" x
3
⁄16" stick - wide side down. Dryfit Rib B into the first slot so
that it holds the balsa stick against the Main Spar. See Figure 2.
Note: In Figure 2, Rib B and the Main Spar are shown upside
down, as constructed. Also note that the end of the stick must
extend slightly past the end of the Main Spar. This will be
trimmed later.
Continue to dryfit Ribs C to J.
Dryfit the remaining
3
/ 8" x
3
/ 16" stick along the Main Spar. Glue with
thin CA, the upper and lower sticks along the Main Spar. (Using
wood glue here would warp the wing due to its moisture
content.) Watch the Main Spar doesn’t develop a curve.
Repeat instructions to create the opposite side of the wing.
(Be careful not to make two left wings.)
Constructing the Leading Edge Spar
Locate Rib F1. (half a rib)
Install Rib F1 against the forward half of Rib F, between
Ribs F and E.
To install Leading Edge Spar, you must first ensure that all ribs are
evenly spaced. Therefore, use the Rear Spar as a tool and dryfit
the Rear Spar into the rear slots of all ribs. Then place the other
Rear Spar over the leading edge of all Ribs to ensure the spacing
is correct. See Figure 3.
Do note Glue the Rear Spars yet.
Glue (wood glue) a
3
/ 16" square stick to the leading edges of Ribs F
to J. Use masking tape to hold the stick in place while glue cures.
Remove the two temporary Rear Spars.
Once the leading edge’s stick has cured, remove the tape.
Repeat for the opposite side of the wing.
