2. Center the 

horizontal stabilizer

, side-to-side, in the 

slot in the fuselage. Also measure the distance from the tips 
of the stab to the center of the fuselage. Adjust the position 
of the stab until the distance is equal.

❏ 

3. Stand back and look at the stabilizer in relation to the 

wing. The stabilizer should be parallel with the wing. If not, 
lightly sand the stabilizer saddle until the stabilizer and wings 
are aligned.

❏ 

4. Insert the 

elevator joiner wire

 in the notch at the back 

of the stabilizer saddle. Use 30-minute epoxy to glue the 
stabilizer in place, being careful that the stabilizer is properly 
aligned. 

Tip:

 Place a piece of masking tape on the top and 

bottom of the stabilizer, just outside the cut covering. Insert the 
stabilizer in the fuse so that part of the bare wood is showing. 

Apply 30-minute epoxy to the wood, top and bottom. Slide the 
stabilizer through the fuse so that approximately 1/2" [12.7mm] 
of bare wood is showing on the other side and apply epoxy 
to the wood. Now align the stabilizer, remove the masking 
tape and wipe off any excess epoxy from the stabilizer and 
fuselage. Recheck that the stabilizer is still aligned.

You can now remove the wings and continue with the 
assembly of the fuselage.

Install the Elevators

❏ 

1. Test fit the 

elevators

 to the stabilizer with the CA 

hinges

If the hinges don’t remain centered, stick a pin through the 
middle of the hinge to hold it in position.

❏ 

2. Install three CA hinges into each elevator half. Install 

the elevators onto the stabilizer with the elevator joiner
