DECAL APPLICATION
The decals in this kit are made of sticky-back mylar with an
extremely aggressive adhesive. They are NOT water activated
transfers. These decals are not die-cut and need to be cut from
their sheets with a sharp hobby knife or scissors. Trim as close to
the image as possible.
Putting sticky-back decals on a model can be tricky! Especially
medium to large size ones like those in this kit. If you don't do it
right you will end up with unsightly air bubbles trapped underneath
the decal. The best method is to put large decals on "wet".
You will need a "soapy water" mixture (water mixed with a very
small amount of dish soap, or SIG Pure Magic Model Airplane
Cleaner, or Fantastic
®
, Windex
®
, or 409
®
type cleaners all work
good). You will also need a supple squeegee (the SIG 4" Epoxy
Spreader #SIGSH678 is perfect for this job), a couple clean soft
cloths (old tee shirts are great), a good straight edge, a ruler, and
a hobby knife with sharp #11 blades. We also suggest that you
have some trim tape handy for making temporary guidelines (1/8"
width or so is perfect) for help in aligning the decals.
First spray the surface of the model where the decal is to be placed
with a soapy water mixture.
Then peel the backing sheet
completely off the decal, being careful not to let the sticky side
double over and adhere to itself. Place the decal onto the wet
surface of the model.
Do not push down! The soapy water
solution will keep the decal from actually sticking to the model until
you have had time to shift it around into exact position. Once you
have it in position, squeegee the excess soapy water out from
under the decal. Mop up the water with a dry cloth. Squeegee
repeatedly to get as much of the water out from under the decal as
possible.
BALANCE THE MODEL
While all airplanes must be balanced to achieve flight, the balance
of an aerobatic airplane like the MAYHEM 40 is especially critical.
The final placement of the longitudinal Center of Gravity, or
Balance Point, will have a great effect on the aerobatic
performance of this airplane.
Balancing this model should be
approached with patience and care.
for the fuel feed tube. Use the longest of the aluminum tubes for
the vent tube. Gently bend the vent tube upwards to 90
O
, so it will
be near the top of the tank.
Adjust the length of the internal
silicone fuel tubing to allow free movement of the metal clunk
pick-up inside the tank. Install the stopper assembly into the neck
of the tank and secure by tightening the clamp bolt.
Be sure to label the "vent" and "carb" lines for later identification.

2) Trial fit the tank in place into the front of the fuselage to
familiarize yourself with how it mounts. The front of the tank should
fit through the hole in the firewall. The main body of the tank is
supported by the contoured hole in the fuselage former. Take the
tank back out of the fuselage.
❑
3) Apply a bead of silicon adhesive around the neck of the tank,
where it will contact the inside of the firewall. Put another big blob
of silicone on the front of the tank just below the neck. Slide the
tank in place into the fuselage, pushing it in until the neck goes into
the hole in the firewall.
❑
4) A 5/16" x 1/2" x 2-7/8" balsa stick is provided to keep the fuel
tank in place. Install the balsa stick across the back of the tank,
gluing it to the front of the fuselage former. This will keep the tank
from sliding backwards in flight. If the tank ever has to be removed
for service, you can break the balsa stick loose to get the tank out.
