Before the First Flight
Although each Blade 400 3D model is factory assembled and tested, you should check the following
before making your first flight:
q
Check the security of all screws and control/linkage balls on your model. Tighten any screws and
control/linkage balls that may be loose and replace any screws, control/linkage balls or other
parts that may be stripped.
q
Check to be sure that the screws securing the main and tail rotor blades in the blade grips are
tightened so that the blades can pivot in the grips when moderate pressure is applied.
q
Check the security of all the plastic ball link ends on your model. The links should stay attached
to the control/linkage balls even when moderate force is applied. Any link that does not stay
attached to the control/linkage ball should be replaced before flight.
q Check to be sure that all electronic equipment and wire leads are secure and will not come into
contact with any moving parts.
q
Check for proper tail rotor drive belt tension. Proper belt tension plays a critical role in achieving
maximum performance and reliability of your model.
If the belt tension is set too tight, it can result in a loss of power while also causing the belt and/
or pulleys to wear more quickly.
If the belt tension is set too loose, the belt can skip and strip teeth from the belt and/or pulleys. It
can also result in a loss of tail rotor performance and control in flight.
You can check the tension of the tail rotor drive belt by using an Allen/hex wrench (or any other
suitable tool/device) to compress the belt through the opening in the main frame and tail boom located
on the right side of the model. Apply light pressure to the exposed side of the belt, compressing it
toward the other side of the belt. The belt tension is set properly if the compressed side of the belt
reaches approximately ½ of the way to the other side of the belt.
If the compressed side of the belt reaches more than ½ of the way to the other side of the belt, the
tension is set too loose. If it is difficult to compress the exposed side of the belt, or if it does not reach
approximately ½ of the way to the other side of the belt, the tension is set too tight.
You can adjust the belt tension by loosening the two screws that mount the horizontal stabilizer and the
four screws that hold the rear section of the main frame together around the tail boom. After loosening
these six screws, slide the boom further into the frame (to loosen belt tension) or farther out of the
frame (to tighten belt tension). After properly adjusting the tail drive belt tension, be sure to retighten
all six screws while also confirming proper alignment of the horizontal stabilizer and tail rotor shaft
(both should be level/horizontal and perpendicular to the main shaft when viewed from behind the
model).
q If this is the first test flight, or a test flight following repairs, you will also want to center the rudder,
aileron and elevator trims.
Your Blade 400 3D is now ready for flight.
Choosing a Flying Area
When you are ready for your first flight, you will want to select a large, open area that is free of
people and obstructions. Until you have properly trimmed, adjusted and become familiar with the
handling of the Blade 400 3D, we suggest that your first and subsequent test flights be made outdoors
in low-wind conditions only.
While it is possible for the Blade 400 3D to be flown indoors, we suggest that it only be in a very large
indoor facility such as a gym (with proper approval) that is also free of people and obstructions. The
Blade 400 3D is not intended to be flown in small indoor areas or facilities where it may be possible to
fly a micro coaxial helicopter like the Blade CX or Blade CX2, or a micro collective pitch helicopter like
the Blade CP+ or Blade CP Pro.
Flying the Blade 400 3D
Having followed the proper ESC and gyro arming and initialization procedures, confirmed proper
control of the servos and motor, and found a suitable flying area, your Blade 400 3D is ready for
flight.
• Slowly raise the throttle/collective pitch (left-hand) stick, increasing the speed of the main rotor
blades until the model begins to lift off. Do not raise the throttle stick too quickly as the model could
climb too fast causing you to lose control or make contact with objects above.
• Lift the model off the ground just a few inches and concentrate on balancing the throttle stick position
so that the model holds a steady hover altitude. In some cases it may be best to make a few short
“hops” to an altitude of just a few inches until you become familiar with the control inputs and trim
settings required to maintain a steady hover and altitude.
