Step 9: Finishing touches, CG and throws
Install your electronics in the usual
manner. If you have a 4 channel radio
you will need to install 2 servo Y-
harnesses to combine the two aileron
servos and the rudder and nose wheel
servos.
The location for the CG is shown to the
right. Adjust the location of the battery
such that the CG lies between 53 and
58mm behind the leading edge of the
main wings, as measured at the
fuselage.
The control throws should be +/- 6mm for
the ailerons and elevators and +/- 10mm
for the rudder. If you are using dual
rates, add and subtract 1.5mm on these
values for high and low rates
respectively.
Important:
!
Pre-flight adjustment and trimming must be done before flying. Check that all
linkages, nuts, servo horns, linkage nuts and screws are tightened.
!
Ensure the flying field is spacious and safe to fly. Bench test the electronic power
system on load for 1 minute.
!
Check all electronic equipment. Range-check the radio equipment. Test all control
surface are moving in their assigned directions before each flight.
!
Check the battery voltage before use, even the batteries are recently charged.
!
After the first flight, it is prudent to check the CG for all subsequent flights.
