Fit the stabiliser
These instructions only apply to installing tailplanes with part number 2A109A0D (for the J230 kit) or
2A032D0D (for the J170 kit). Older tailplanes require different instructions.
These fitting instructions also apply to the special short horizontal stabiliser (P/No 2A109F0N, for the
J230 kit) which is about 300mm shorter then 2A109A0D and uses large end caps to make up the
difference.
Note:
It is important that you determine which horizontal stabiliser
you have.
Prepare the stabiliser by taping up the inboard elevator hinges to prevent any resin getting into the
hinge pins barrels. From the previous task you will have a marked centreline on the stabiliser: test fit
the stabiliser to the rear of the fuselage using the stabiliser centreline as a lateral location guide against
the fuselage centreline.
Push the stabiliser fully forward into the rear of the fuselage and check that each end of the stabiliser is
an equal distance back from the straightedge
–
use 2 tape measures as shown circled above, one each
side, and carefully move the stabiliser until the measurements are exactly the same. Sight along the
fuselage from the rear and confirm that the stabiliser is level and lined up with the straightedge. The
chord line of the stabiliser is to be angled down
1.5 degrees
at the leading edge. Make any adjustments
necessary.
When the stabiliser is aligned correctly, secure the stabiliser to the fuselage with self-tapping screws,
using 10 screws per side. These screws will be removed after the stabiliser has been finally fitted. Run a
pencil line around the stabiliser along the fuselage join.
Remove the stabiliser from the fuselage and remove the peel cloth from the rear of the fuselage, then
lightly sand all the surfaces to be joined
–
the pencil line on the stabiliser will act as a guide for where
to sand and where to coat with resin.
