HOW TO CUT COVERING FROM BALSA Use a soldering iron to cut the covering from the stabilizer. The tip of the soldering iron doesn’t have to be sharp, but a fine-tip does work best. Allow the iron to heat fully. ❏ 2. Center the horizontal stabilizer in the slot in the fuselage. Stand back and look at the stab in relation to the wing. The stab should be parallel with the wing. If not, sand the stab saddle until the stab and wings are aligned.
