Those few of us who still build from plans or kits have long known that
wax paper offers less-than-satisfactory protection of plans when gluing
with CA. Here is a solution: Use the backing sheets from your covering
film instead. CA absolutely will not stick to this stuff. Save the large
pieces from covering wing panels, and use them to protect your plans.
Saving money while recycling—it’s a win-win!

Lock it DowN
Here’s an easy method to help hold canopies in place. Take a 1/8-inch-
thick piece of rubber sheet, cut just a small piece to fit onto the back
side of the blind nut, and carefully glue it in place with CA glue. Once it is
trimmed to fit, drill a 1/16-inch-diameter hole from the front side through
the rubber. When the canopy screw goes through the back side of the
blind nut, the rubber acts like a nylon locknut. This keeps the screws from
backing out and getting lost, saving you time and money.

MakiNg the cut
Straightedge rulers tend to slide when you run a knife along them to strip
balsa or to make cuts in covering. To help guide your blade with more
authority, use a cork-backed stainless-steel ruler. The cork will grip
slippery surfaces, allowing you to create a straight cut on your balsa or
covering. The cool thing is that the ruler will flex and follow the contour of
a wing or fuselages. The cork-backed ruler can also be used for making
panel lines on your plane because of its flexibility and straight edge.

Dot MarkS the Spot
To mark the center-of-gravity balance points on the wings of your model
airplanes, first run a piece of 1-inch-wide low-tack tape along the wing
where it meets the fuselage. Then measure the prescribed distance from
the wing’s leading edge and make a mark on the outer edge of the tape. At
that mark, stick an adhesive-backed door bumper to the wing and then
remove the tape. The bumper is easy to locate by feel when checking the
center of gravity, and because it’s transparent, it can’t be seen.
