blade to increase and the speed of the upper main rotor blade to decrease. If both rotor blades are not
responding properly to rudder input, simply reverse the locations of their motor plugs on the 5-in-1
unit.
With both rotor blades rotating in the correct directions and responding properly to rudder inputs, your
Blade mCX2 is ready for flight. But you will need to review the following sections of the manual BE-
FORE proceeding with the first flight.
Understanding the Primary Flight Controls

Dual Rates

This feature allows the pilot the toggle between the high and low control rates available for the aileron,
elevator and rudder channels. To toggle between the high and low rates, push in on the right-hand
stickonthetransmitter(whilethetransmitterispoweredon).

Note: The throttle curve in the low rate mode is also different than it is in the high rate mode. This
makeslow-rate-modethrottlesmootherandeasiertocontrol.
Choosing a Flying Area
When ready for your first flight, select a relatively open indoor area free of people and obstructions.

Once you properly trim your helicopter and become familiar with its handling and capabilities, you will
be able to fly in other smaller, less open areas.

Flying the Blade mCX2
Note: In addition to reviewing the flight maneuvers outlined below, we recommend you watch Videos
located on the product page for the Blade mCX2 on www.horizonhobby.com to see many of these
maneuvers and adjustments performed by the helicopter and pilot.
• Slowlyraisethethrottle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

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.
As you will find, the Blade mCX2 requires minor throttle adjustments to maintain its altitude in
hover.Remembertokeepthesethrottleadjustmentsasminimalaspossibleaslargeadjustments
could result in a loss of control and/or a possible crash.

find the helicopter constantly drifts without any directional control input, it will be best to land
themodelbeforemakinganyadjustmentstothetrimsettings.Additionaldetailsregardingthe
location and function of the trim buttons can be found in the “Understanding the Primary Flight
Controls” section of this manual.
- If the nose of the helicopter drifts to the left or right, adjust the rudder trim.
-Ifthehelicopterdriftsforwardorbackward,adjusttheelevatortrim.
- If the helicopter drifts to the left or right, adjust the aileron trim.
Continuemakingtrimadjustmentsuntilthehelicopterhoversatalowaltitudewithverylittle

besttohavethehelpofanexperiencedhelicopterpilottotrimthemodelforyoubeforemaking
your first flight.
• With your Blade mCX2 properly trimmed and maintaining a stable low-level hover, practice using
the rudder, elevator and aileron controls to familiarize yourself with the helicopter’s responses to
controlinputs.Remembertokeepthecontrolinputsasminimalaspossible.
When comfortable with low-level hovering, you can transition to hovering and flying the helicop-
ter at higher altitudes of three to four feet. At these higher altitudes you will become comfortable
with the flight characteristics of the Blade mCX2.
• If you feel the helicopter drifting out of control during flight, release all of the
controlsexceptforthrottle.Youwillneedthrottletomaintainaltitude,butbecauseoftheinherent

• IN THE EVENT OF A CRASH OR ROTOR BLADE STRIKE, NO MATTER HOW MINOR OR MAJOR,
LOWER THE THROTTLE STICK TO THE LOWEST POSSIBLE POSITION AS QUICKLY AS POSSI-
BLE TO PREVENT DAMAGE TO THE ESCS OF THE 5-IN-1 UNIT. ALSO BE SURE THE THROTTLE
TRIM IS SET TO THE MIDDLE POSITION OR TO A LOWER THAN THE MIDDLE POSITION.
Failure to lower the throttle stick to the lowest possible position in the event of a crash
could result in damage to the ESCs in the 5-in-1 unit, which may require replacement of
the 5-in-1 unit.
Note: Crash damage is not covered under warranty.
