❏

12. Use a fine-point felt-tip pen to mark a line behind the

strut brackets on both sides of the bottom wing 3/4" [19mm]
from the aileron hinge line. Fit the right strut to the wing
against the outside of the brackets. The aft end of the strut
should be contacting the line you marked. You’ll know you’ve
selected the right strut because the top and bottom will be
angled correctly to fit the top and bottom wings.

❏

13. Mark the holes in the bottom strut brackets onto the strut.

❏

14. Drill 1/8" [3.2mm] holes at the marks. Bolt the strut

into position with two 4-40 x 1/2" [13mm] socket head cap
screws, flat washers and lock nuts.

❏

15. Mark and drill the holes in the top of the strut the

same way. Mount the strut to the top and bottom wing.

❏

16. Mark and drill the bottom holes in the left strut, then

mount the strut.

❏

17. Holding the top wing and left strut together, mark the

holes in the top brackets onto the strut. It’s okay if pressure
is required to hold them together. The struts will hold the
wings at the correct incidences.

❏

18. Remove the left strut, drill the top holes, then mount

the strut to the top and bottom wings.

Now the wings are mounted! If you will be mounting the
optional flying wires, skip the following two steps, then
return and perform these steps after the wires have
been mounted.

❏

19. If not mounting the optional flying wires, lift the model

at the recommended balance point on the tape lines previously
marked on the bottom of the top wing. The strongest part of the
top wing is where the center panels join the outer panels, so
this is a good place to lift. Be certain your fingertips are on the
middle lines, not on the forward or aft lines.

❏

20. Observe whether the tail or nose drops, indicating a

tail-heavy or nose-heavy situation. This will give you an
indication of where to mount the receiver battery inside the
fuselage to reduce or eliminate any additional lead ballast
that would be required to balance the model. Make a mental
note (or write it down on a piece of paper) whether you will
be mounting the battery pack in front of, behind or directly
below the cockpit.
