Fuselage
☐
Inspect the wings for any warps that may
have worked their way in when covering or
while the model was in storage, and remove
prior to flight.
DO NOT ATTEMPT FLIGHT IF
THE WINGS ARE WARPED.
Lack of aileron
control on this model will make contending
with a warped wing very difficult.
FIX THE
WARP.
☐
Center the rudder, then set the direction, rate
of travel, and dampening (expo).
The Rudder servo should be controlled by the
Aileron channel of your radio, as Rudder on
this model also controls the roll of the aircraft.
Rudder should follow aileron stick travel, i.e.
moving the Aileron stick to the
RIGHT
should
move the Rudder to the
RIGHT
of the aircraft.
The Elevator servo will control the pitch of the
main wing, and should be controlled by the
Elevator channel of your radio. Review Step
107 in this manual for the correct setup of the
elevator servo, wing saddle and pushrod.
Pulling
BACK
on the Elevator stick should
cause the main wing to pitch
UP
and
BACK
,
at or near the
FORWARD
mark on the wing
pylon. Pushing
FORWARD
on the stick
should cause the main wing to pitch
FORWARD
. The
FORWARD
motion of the
wing should not exceed the
REAR
mark on
the wing pylon.
EXCEEDING THIS MARK IS
NOT RECOMMENDED AND WILL CAUSE
ERRATIC OR UNCONTROLLED FLIGHT!
With the pushrods connected per the
instructions in this Assembly Manual, the the
control throws should be as follows:
Rudder Travel
(rudder is VERY effective)
Low Rate +/- 12 degrees 30% expo
High Rate +/- 15 degrees 50% expo
Elevator
(Wing) Travel
Low Rate +6 degrees
30% expo
-2.5 degrees
30% expo
High Rate +8 degrees
50% expo
-3 degrees
50% expo
The above Exponential settings apply only to
computer radios.
Pre-Flight
Have and experienced pilot assist you with pre-
flighting your new model. Just like having
someone proof read something you’ve written,
having a second
fresh
set of eyes to inspect your
final product is often helpful at avoiding disaster.
While not an exhaustive pre-flight check these are
some of the major items that you should consider
using when developing your own pre-flight check
list. Get in the habit of always pre-flighting your
models before each and every flight.
☐
Weight and Balance
- Check the
S-POU!™
(300)’s
balance. The model should balance
at the point pre-marked on the main wing
saddle. Shift radio equipment and/or add or
remove ballast to correct a balance problem.
Use your right and left hand index fingers and
suspend the model from below, between the
marked CG measurements. Site from profile
of aircraft against horizon. If the upper edge
of the fuselage side appears to hang level
with horizon line, then the
S-POU!™ (300)
is
properly balanced to fly.
☐
Check Weather
- The
S-POU!™ (300)
first
flight should be outdoors and in
zero
wind
conditions. The
S-POU!™ (300)
is capable of
flying in winds up to 8-10 mph so long as the
pilot is capable.
☐
Inspect airframe
for warps and obvious signs
of wear or damage. Do not fly a damaged or
warped model.
☐
Inspect control surfaces
for center, proper
direction of travel, rate of throw, secure
pushrod connections, hinges, and receiver/
servo mounting hardware.
☐
Check wing attach points
for damage and/
or wear. Inspect rubber bands, that they are
installed correctly and in good condition to
adequately retain wing.
☐
Inspect battery for full charge.
Never begin
a flight with a partially charged battery.
☐
Clear prop!
Before applying power to the
model, clear and keep clear of the prop arc.
☐
Range check radio.
Follow the radio makers
guidelines for performing a proper range
check.
