MOTOR SET UP
Be sure the motor is properly broken in using the
manufacture instructions. Set the throttle throw to
shut the motor off when the trim is pulled down
and idles reliably with the trim up.
After the motor is set, run one tank of gas at full
throttle, measure how much time it takes to run the
tank dry.
CONGRADULATIONS you are now ready for
test flights.
Before leaving for the field be sure your batteries
are fully charged and you have all the required
support equipment {fuel, starter, glow driver, etc.}.
Although the HURRICANE will fly well in wind,
wait for a nice day.
At the field have a helper hold the airplane,
following the radio manufactures instructions
perform a range check of the radio. Do this with
the motor off, start the motor and do it again.
Perform this test
EVERY TIME YOU GO TO FLY!
TRIMING BASIC FLIGHT
The HURRICANE is NOT a trainer. A true
aerobatic aircraft, it goes only where you point
it and will not recover to level flight without
control input. If you do not have high
performance experience seek the help of
someone who does.
Line up on the center of the runway and slowly
open the throttle, using the rudder to maintain
directional control. Once the tail is up apply a little
up elevator and allow the plane to gently lift off the
runway. Keep the climb angle and turns shallow
until you reach a safe altitude. Reduce the throttle
to about 60% power. With the airplane flying away
from you adjust the radio aileron trim tab till the
wing stays level. Turn and line up the plane with
the runway. Adjust the elevator trim till the plane
maintains level flight. Once again with the airplane
flying away from you adjust the rudder trim till the
fuselage tracks straight {it may be necessary to
correct the aileron trim after this procedure}.
Continue to fly and trim until the aircraft is
tracking well, land before the fuel runs out. Carry a
little power on final approach until over the end of
the runway, then cut power to idle, hold the plane
just off the runway till the airspeed bleeds off and
the plane settles on. If the landing is too long add
power go around and try again, don’t try to force it
to the ground.
Now its time to zero out the trims. To do this
measure the control location, center the trim tab
on the radio and adjust the servo horn for large
changes, the control clevis for small changes.
For example if after the flight the rudder is 3/16
inch to the right, center the radio trim and
adjust the clevis till the rudder once again
measures 3/16 right. By doing this whenever you
fly, setting the radio trims at center will result in
a well-trimmed plane. Increase the control
travel, as you become more familiar with the
flight characteristics until loops take about 50
feet and knife edge can be maintained with 80%
stick deflection. Final roll rate should be 300-
360 degrees per second.
If you have followed the procedures in this
Manuel you will now be rewarded with one of
the finest flying sport models available. All
primary aerobatic maneuvers are at your
fingertips and the aircraft will perform them
with ease. No further trim work will be required
until you are ready for unlimited and advanced
3-D flight. Before attempting any of the
ADVANCED FLIGHT TRIM procedures you
must be completely comfortable with inverted
and knife-edge flight. The following trim
sequence is very time consuming and you may
not be able to complete it in one day. Every
change made during this procedure will affect
all others so it will be necessary to start the
procedure from the beginning after each
adjustment.
ADVANCED FLIGHT TRIM
All the following tests should be performed at
80% power unless noted.
