Fit the elevator end caps
Assemble the horizontal stabiliser and the elevator by inserting all of the hinge pins and set
the elevator to a level position.
Use a knife to trim out some of the foam in the end of the elevator and then test fit each end
cap. Ideally you want a gap between the end of the horizontal stabiliser and the elevator end
cap (yellow arrows above) the thickness of 2 mixing sticks. When this gap has been achieved,
align the rear of the end cap with the rear of the elevator and fit with self-tapping screws.
Check that the elevator can swing freely: if there is any binding or rubbing between the end
cap and the horizontal stabiliser locate the source and fix it, either by moving the end cap
position slightly or by sanding away part of the inside of the end cap.
Remove the end cap and sand all surfaces to be joined, then mix a batch of resin and coat
those surfaces. Add flock to the remaining resin and apply a 2mm layer to the end cap stub
then fit the end cap to the elevator and fix in place with the self-tapping screws. Smooth away
any excess flock with a mixing stick, recheck the alignment and leave overnight to cure. Next
day remove the self-tapping screws.
Fit the horizontal stabiliser end caps
With the horizontal stabiliser and the elevator still assembled, test fit the horizontal stabiliser
end caps: the gap between the elevator end cap and the horizontal stabiliser end cap should
also be the thickness of 2 mixing sticks (green arrows above). When this is correct fit the end
cap with 3 self-tapping screws: 1 at each back corner and 1 at the leading edge. Check for
freedom of movement then remove the end cap and prepare the surfaces and flock the end
cops into place and fix with the self-tapping screws. Smooth away any excess flock with a
mixing stick, recheck the alignment and leave overnight to cure. Next day remove the self-
tapping screws.
Separate the horizontal stabiliser and the elevator. The horizontal stabiliser will be fitted to the
empennage in the task
Pre-paint>Fuselage>Empennage>Fit horizontal stabiliser and the
elevator will then be fitted to set the up and down stops.
This completes the Pre-Paint>Fuselage>Empennage>Fit elevator task.
