CENTER THE CONTROL SURFACES
Use the trim buttons to center the positions of the
control surfaces.
CENTER OF GRAVITY
The recommended balance point is 2-5/8" [67mm] from the
forward edge of the battery compartment. Do not apply any sort
of tape to the decaled areas of the plane. Peeling off the tape
will most likely lift the decals. Instead, we recommend marking
the recommended balance point with very small marks using a
felt-tip pen. With the battery installed in the battery compartment
and the canopy hatch in place, use a Great Planes C.G. Machine
or use your fi ngers to lift the Eraze upside down at the marks
that you made. With an ElectriFly 7.4V 600mAh LiPo the plane
should be close to balancing at the recommended balance point.
If the plane tips forward then it is nose-heavy and weight will
need to be added to the tail of the plane. If the plane tips back
then it is tail-heavy and weight will need to be added to the nose
for it to properly balance. Stick-on lead weight can be used to
balance the plane (GPMQ4485). If you have added weight, be
sure to re-check the balance point of the plane before fl ying.
Later, you may wish to experiment by shifting the C.G. up
to 3/16" [5mm] forward or 3/8" [9.5mm] back to change the
fl ying characteristics. Moving the C.G. forward may improve
the smoothness and stability, but the model may be less
responsive during launch, aerobatics, and will require a longer
glide during landing. Moving the C.G. aft makes the model
more maneuverable, but could also cause it to become too
diffi cult to control. In any case, start at the recommended
balance point and do not at any time balance the model
outside the specifi ed range.
ARM THE MOTOR
The Eraze requires that an arming routine be completed before
the motor will operate. With the transmitter on and the throttle
stick in the idle position, connect the fl ight battery to the ESC.
Move the throttle all the way up and listen for the beep. Move the
throttle back to idle and you will hear two beeps confi rming the
motor is now armed. Moving the throttle up will now cause the
motor to operate! Keep items and fi ngers clear of the propeller.
CHOOSE A FLYING SITE
The Eraze is a fast fl ying model and an adequate space free
of trees and buildings is required. A park or open fi eld that is
at minimum the size of two football fi elds side-to-side with no
obstructions or your local AMA sanctioned fl ying fi eld would
be ideal. The Eraze can handle winds as much as 10 mph.
However, we recommend your fi rst fl ew fl ights be done in
calm conditions so you can safely trim the model and become
accustomed to its fl ying characteristics.
RANGE CHECK
As a precaution, an operational ground range test should be
performed before the fi rst fl ight each time you go out. Performing
a range test is a good way to detect problems that could cause
loss of control such as low batteries, defective or damaged
radio components or radio interference. This usually requires
an assistant and should be done at the actual fl ying site you
will be using. First turn on the transmitter, then install the
fully-charged battery into the fuselage. Connect the battery
and install the hatch. Remember, use care not to “bump”
the throttle stick. Otherwise, the propeller may turn and
possibly cause damage or injury. To range check the Tactic
TTX404 radio control system, switch on the transmitter and
connect the motor battery to the ESC. Set the model on the
ground and have an assistant hold the model. Walk 100' [90m]
from the model and while pointing the transmitter at the plane,
operate the controls ensuring that the plane’s surfaces operate
according to the transmitter inputs. Operate the motor at
different rpm. Have your assistant alert you if the controls quit
responding or move suddenly or erratically. If you are using a
different radio control system, follow the instructions that came
with your radio control system to perform a ground range check.
