Tips From The Pros; Control Surface Hinging - Model Tech Mini Mach Racer Assembly Instructions Manual

During the covering process, sometimes color may smear slightly from the seams. If you see any smeared colors on the covering
l
material, they can be quickly removed by simply wiping them off with a paper towel and a small amount of acetone.
Make sure to test-fit the parts together before applying glue. This will ensure that the parts fit properly before gluing them together.
l
When gluing anything that has a smooth surface, it's important to lightly roughen the gluing surfaces with 220 grit sandpaper. This
l
will allow the glue to stick better. Also, never glue directly to the covering material. Always remove the covering material from the gluing
surfaces prior to gluing the parts together.
When cutting away the covering material from the gluing surfaces, be careful to cut only through the covering material. Try not to cut
l
down into the balsa structure because that can compromise the integrity of the airframe.
We do not suggest storing your aircraft in an extremely hot environment (like the back of your car in direct sunlight) for any length of
l
time. The extreme heat could cause the covering material to wrinkle or sag and possibly damage the fragile components of the radio
control system and/or LiPO battery.
Epoxy can be cleaned up before it dries using rubbing alcohol, and C/A can be cleaned up before it dries using C/A Debonder.
l
To prevent current loss, make sure to use high-quality connectors between the battery and the ESC, and between the ESC and
l
the motor.
Insulate solder joints with heat-shrink tubing to prevent short circuits and corrosion.

IMPORTANT The hinges are NOT glued into place from the factory, they are simply slid into place dry for shipping purposes. You
must glue them into place.
C/A-style hinges are used to hinge the control surfaces. These hinges are designed to be glued into place using thin C/A. Do not
glue these hinges into place using any other type of glue, such as thick C/A or epoxy. Use of any adhesive other than thin C/A could
result in failure of the hinges during flight.
For flutter-free control surfaces and crisp control response, it is imperative that the hinges be glued in properly. This is achieved by
having a tight hinge gap [no more than 1/32" (.7mm) wide] and using plenty of thin C/A glue. Poor hinge installation can lead to control
surface flutter which can result in a catastrophic failure of the airframe.
q Remove the two elevons and the six C/A-style hinges from the wing.

PRO TIP The T-Pins will keep the hinges centred and square to the hinge
line while you are hinging the elevon.
