Setup
☐
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 will be controlled by the elevator
channel of your radio. Moving the elevator
stick back should move the elevator up,
moving it forward should move the elevator
down.
Fly Baby Bipe (UM)
is designed to be a very
docile flyer, therefore the flight controls are
set up for fairly minimal throws. With the
pushrods connected per the instructions in
this Assembly Manual, the control throws
should be as follows:
Rudder Travel (rudder is VERY effective)
Low Rate +/- 12 degrees 30% expo
High Rate +/- 15 degrees 70% expo
Elevator Travel
Low Rate +/- 12 degrees 30% expo
High Rate +/- 15 degrees 70% expo
The above Exponential settings apply only to
computer radios.
Pre-Flight
Have an 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
Fly Baby
Bipe (UM)
balance. The model should
balance on the mark etched on the bottom of
the upper wing at the wing tips.
☐
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 along F4/F8 appears to
hang level with horizon line, then the
Fly
Baby Bipe (UM)
is properly balanced to fly.
Move the battery within fuselage to obtain
proper balance.
☐
Check Weather
- The
Fly Baby Bipe (UM)
first flight should be outdoors and in
zero
wind conditions. The
Fly Baby Bipe (UM)
is
capable of flying in winds up to 5 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 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.
☐
Check for traffic.
Proceed to the flight line
(With your mentor/instructor if you are a
novice pilot) and observe other RC traffic. If
the runway is clear, and no one is in the
pattern to land, loudly announce your
intentions to take off. Remember etiquette
dictates that all aircraft on ground must yield
the runway to those landing.
