Glue a servo mount under the wing and between the first and second rib, attached to the second rib
and the vertical spar. Glue a 2.75”x.5”x1/8” balsa servo mount reinforcement under the servo
mount and behind the rear servo backing plate.
!
Build the second wing.
Make sure that you are building a mirror image so that you don’t end
up with two of the same side.
Covering the wings
The MiniFlash kit comes with a clear, paintable covering called Doculam which is actually a
laminating film. The frosted side has a heat activated adhesive. Unlike most coverings, Doculam
does not have a backing sheet. Compared to SoLite (Solarfilm Lite – another excellent choice for the
MiniFlash), Doculam is stronger, heavier, and needs a higher temperature to adhere and to shrink.
!
Lay the wing on the table and cut a piece of covering so that it overlaps the wing by ~2”.
!
Tack one corner of the trailing edge then the other corner of the trailing edge with a covering iron,
ensuring that the covering is tight.
!
Pull the covering tight and straight then tack the two corners of the leading edge.
!
Tack down the entire leading and trailing edge. Wrap the covering around the back of the trailing
edge and tack it down across the back of the trailing edge.
!
Pull the covering tight across the high point of the wingtip and tack.
!
Here’s the fun part: work the covering around the curve of the wingtip so that the wrinkles are
evenly distributed. This will make shrinking the wrinkles out easier.
!
Tack down the covering to the inner rib.
!
Trim the covering so that there is a 1/8”-1/4” overlap around the inner rib. Tack down the overlap
to prevent the covering from pulling away when you shrink it.
!
Cover the other side.
!
Once both sides of the wing are covered, shrink the covering with a covering iron or heat gun. If
you are using the supplied clear covering, you will need a fair amount of heat to shrink the
covering but too much heat will result in a hole.
!
Tack the covering down around the servo holes then cut the holes out with a sharp Xacto.
!
You can paint the supplied covering with Testors car body paint, which has been specifically
designed for lexan car bodies.
