TIPS & TRICKS
RACK 'EM!
Unless you're wealthy enough to add a new wing onto your house to serve
as a 1/4-scale hangar, chances are that you have to store your models in a
limited area. A great way to make the most of the space you have is to
build a hanging rack out of 1/2-inch PVC pipe. You'll need about 4 feet
of tube, four 90-degree elbows and two 45-degree elbows. Cut the
tube into seven pieces: a top crosspiece, two medium-length diagonal
extensions, two short vertical extensions and two long longitudinal
extensions—exact lengths will vary, depending on the size of your air-
plane. At the midpoint of the crosspiece, drill a 3/16-inch hole to fit
a 2-inch deck screw, from which you will hang the rack.
When all the angles are squared, glue the pipe together,
and just like that, you'll have a multipurpose plane rack for
less than $2 in parts.

BULLETPROOF YOUR PLANE
Kevlar weave is one of the strongest materials
around; it's no coincidence that it is the prime
ingredient in airbags and police body-armor. Ounce
for ounce, it's much stronger than fiberglass, and as
such, it's great for laminating into an airplane to
reinforce high-stress areas such as firewalls, wing
supports and landing-gear mounts. An inexpensive
source for Kevlar is an auto junkyard; deflated
airbags are easily found in late-model wrecks.

SAWDUST-FREE WORKSHOP
Here's a neat way to keep sawdust under control in your workshop.
Take a standard box fan with a rectangular shroud and duct-tape a
filter element from a forced-air heater/air conditioner onto the
intake side of the fan. These filters are available in various sizes
and can be found at hardware and home-improvement stores; they
can be trimmed to fit, if necessary. Be sure to seal the edges well
with the duct tape. When you turn on the fan, the intake air
will be drawn through the filter. If you position
the intake side near you as you
sand, the sawdust will collect in
the filter instead of all over your
workshop (and you).

ALL-TEMPERATURE PUSHRODS
The plastic pushrods that are included in many kits can stretch or contract, depending on the temperature. This can throw off your trim settings and put
extra stress on parts. A good way to avoid this problem is to run a length of wire through the center of the plastic-tubing pushrods. You can solder the cle-
vises to the wire, which makes a stronger joint. More important, the wire will not be affected by temperature changes. The plastic pushrods now serve as
support for the wires.
