Construction Manual

Step 6 - Center Section (F6)

Locate F6 from LP3 Glue it in position 

making sure it is 90° from R1.

Step 7 - Center Section (F6)

Locate F8, F9 and R0 from LP3 

Glue F8 in position making 

sure it is 90° from R1. Once 

the glue has cured, position R0 

and F9 in position as shown, 

making sure that R0 fits in 

the center notch of F9. Once 

they are aligned properly, glue 

them in position.

Step 8 - Center Section (attach the other R1)

Locate the remaining 

R1 assembly. Glue it 

in place as shown, 

making sure all of 

the tabs from F5, F6, 

F8 and F9 fit into the 

slots on R1. Make 

sure both sides are 

straight and parallel.

Step 9 - Center Section (F7)

Locate F7 from LP3. This fits on the 

underside of the center section and 

the rounded side points towards 

the firewall. Once satisfied with the 

fit, glue in position.

Step 10 - Center Section (attach R1Ds)

Locate the two R1D 

pieces from BP3. 

These are glued to 

the outside of the 

R1s and will act as a 

shelf when attaching 

the  forward sheeting 

later on in the build. 

Use the lightening 

cutouts and the 

extended tabs on F6 

to properly align these pieces.

Step 11 - Center Section (affix to building surface.)

With the main work on the center section finished, it is time to 

attach it in place over the plans. Carefully pin it in position making 

sure it’s straight and true. When in position, locate the 2 TEJ pieces 

from BP2. These 

are jigs used to 

properly space the 

ribs. These pieces 

are symmetrical so 

no worries about 

 

placing them in the 

wrong direction. 

Pin these in place 

as shown on the plans, over the trailing edge. Use a long straight 

edge to assure that both edges line up. The inner notch will fit 

around the extended tab on the back of the R1 pieces.

Step 12 - Wing Assembly (R2s)

Locate both R2A pieces from LP1 and 

both R2B pieces from the LP2. Align 

the curvy cuts in R2A and R2B to create 

a finished R2. Pay attention when 

joining so you align the engraved 

circles next to each other. Make two 

finished R2 pieces.

All of the following steps to build the wing should be 

performed to construct both the left and right wing at the 

same time. 

Step 13 - Wing Assembly (LEJ)

Locate both LEJ pieces from BP2. These are also jig pieces and 

will be used to locate the forward tabs on each of the ribs. The 

un-notched end will fit up against the center section and will angle 

rearwards towards the outer rib. Do not pin in place yet.

Step 14 - Wing Assembly (R2s)

Locate both completed R2 

ribs. Carefully place these 

in position, one on each 

side of the center section. 

The rear tab will fit into the 

REJ jig and the front tab 

will fit into the LEJ jig.

Step 15 - Wing 

Assembly (ribs R3-R5)

Locate both R3 ribs from 

LP2 and both the R4 

and R5 ribs from the BP1 

sheets. Carefully place 

these in position. The rear 

tabs will fit into the REJ jig 

and the front tab will fit 

into the LEJ jig. Make sure 

the tabs are pushed all the 

way into the jigs, so they are resting on the plans.

When satisfied of the alignment, pin  both LEG jigs into place on 

to your building board.
