3) Using a 1/16” drill bit, drill a hole through
the side of the fuselage, near the receiver, for
the antenna to exit. Route the antenna out of
the fuselage and secure it to the vertical stabi-
lizer using a rubber band and a modified servo
arm. See picture as below.
When balancing the airplane you may
need to move the battery or receiver for-
ward or after to achieve proper balance.

PILOTS INSTALLATION.
!
1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
your plane to lose control and crash. The cen-
ter of gravity is located 6.5cm-7.5cm back
from the leading edge of the wing measure at
the wing tip. Balance the
PT-19
upside down
with the fuel tank empty.
BALANCING.
CONTROL THROWS.
!
1) We highly recommend setting up
the
PT-19
using the control throws listed be-
low. We have listed control throws for both
initial test flying/sport flying and aerobatic fly-
ing.
!
2) If the nose of the plane falls, the plane
is nose heavy. To correct this first move the
battery pack further back in the fuselage. If
this is not possible or does not correct it, stick
small amounts of lead weight on the fuselage
sides under the horizontal stabilizer. If the tail
of the plane falls, the plane is tail heavy. To
correct this, move the battery and receiver
forward orif this is not possible, stick weight
onto the firewall or use a brass heavy hub spin-
ner hub, similar to those offered by Harry Higley.
When balanced correctly, the airplane should
sit level or slightly nose down when you lift it
up with your fingers.
