INSTALL THE TAIL

Install the Horizontal
Stabilizer & Elevators
❏
1. Temporarily fi t the wing to the fuselage using two 3mm
x 25mm machine screws and two 3mm washers.
❏
2. Use some 220-grit sandpaper to roughen the ends of
the elevator joiner wire.
❏
3. Test fi t the joiner wire into both elevator halves and lay
the joined elevators on a fl at table. Both elevators should lie
fl at. If they are not aligned, remove the joiner wire and twist
it slightly using two sets of pliers. Note: DO NOT attempt to
twist the joiner wire while it is installed in the elevators. You
will damage the wood! Remove it completely and make a
small adjustment. Then re-check it.
❏
4. Place the elevator joiner wire in the horizontal stabilizer
slot and slide it all the way back in the slot. Center the
stabilizer in the slot and slide it all the way forward.
❏
5. Align the trailing edge (TE) of the stabilizer left to right
so that distance A = A1. Align the stabilizer tips fore and
aft so that distance B = B1. Use a fabric measuring tape to
measure these distances.
❏
6. Prop the tail up and take a few steps back from the
model. Check to see that the tips of the horizontal tail are at
an equal distance from the wing so that C = C'. If one side
is higher than the other, remove the stabilizer and sand the
bottom of the stab slot slightly (on the high side) and recheck
the alignment.
❏
7. When you're satisfi ed with the alignment of the stabilizer,
wick thin CA into each joint.
