• To complete installation and wiring hook-up of the brushless ESC, connect the remaining JST male connector of
the battery power lead Y-harness to the female JST connector of the 2-in-1 control unit. Be sure to then secure
the battery power leads of the brushless ESC and 2-in-1, along with the now unused main motor power lead
of the 2-in-1 unit, so they cannot come into contact with the gears or any other moving parts, and so you can
readily access the remaining JST female connector for connecting the battery pack .
Now that you have completed installation of the optional brushless power system, it will be necessary to check
that the ESC is properly programmed to ensure maximum performance, and that the motor is operating in the
correct direction . However, before proceeding with these checks, unplug the tail motor from the 2-in-1 control
unit . Also, remove the main rotor blades and mounting bolts/nuts from the main blade grips to help ensure safety .
Then, follow these steps if using the E-flite 20-Amp brushless ESC (EFLA311B):
• Turn the transmitter on first and advance the throttle stick to full power. Then, after placing your hand on the
rotor head and securing the helicopter so it will not be able to move and you can quickly disconnect the battery
if power to the motor is applied, plug the battery into the battery lead Y-harness connected to the 2-in-1 control
unit and brushless ESC. You should then hear the beep to signal power up of the brushless ESC, followed by an
additional beep to indicate that the ESC has entered the programming mode .
Note: Exercise extreme caution and care when programming the brushless ESC with the motor pinion
gear meshed properly to the main gear. Although the ESC is equipped with safe power-on software
and should not apply power to the motor, you must still be very careful. If, at any time, power to the
motor is applied and the rotor head begins to spin, unplug the battery immediately to prevent any
damage to the model and electronics, or even personal injury.
• Follow the instructions included with the ESC to set the programming for the brake and voltage cutoff to the
following:
Voltage Cutoff – Auto LiPo ON
Note: With the voltage cutoff programming set to Auto LiPo ON, a soft cutoff of motor power (usually
noticeable as a quick “pulsing” of motor power under load) will occur when the voltage of the 3S LiPo battery
pack reaches 9V under load . This is generally preferred in most cases, however, you can disable the Auto LiPo
soft cutoff entirely by setting the voltage cutoff programming to Auto NiCd/NiMH ON . In this mode, soft cutoff
of motor power will not occur until approximately 5 .0V under load, even when using a 3S LiPo battery pack for
power . However, this means you must exercise extreme care to prevent over-discharging the LiPo battery pack
during flight .
Brake – OFF
Note: It is extremely important that the motor brake of the ESC is disabled in order to prevent damage to the
main gear and other components .
Once you have confirmed that the ESC’s programming for the voltage cutoff and braking is correct, disconnect the
battery from the power leads. You will now need to confirm that the motor is operating in the correct direction.
• Turn the transmitter on first and lower the throttle stick and trim completely. Then, plug the battery into the
battery lead Y-harness connected to the 2-in-1 control unit and brushless ESC. You should almost immediately
hear beeps from the brushless ESC to indicate that it is armed and ready for use .
Note: The brushless ESC will almost always arm before the 2-in-1 control unit. This is extremely
important to remember because the main motor will then run if the throttle stick is advanced, even if
the 2-in-1 has yet to arm. Be certain to exercise extreme caution when waiting for the 2-in-1 control
unit to arm, especially if the brushless ESC has already been armed.
• Once the brushless ESC has armed properly, you have placed the helicopter in a safe place free of obstructions,
and are clear of the flybar paddles, you can safely power up the model to check the operating direction of the
motor .
• Advance the throttle stick slowly, just until the flybar paddles begin to spin, and note the direction they spin.
The flybar paddles should spin clockwise when viewed from the top . If they are spinning in the wrong direction,
unplug the battery, then simply reverse the order of any two of the brushless motor leads where they connect
to the ESC . Then, repeat the test to confirm that the flybar paddles (and motor) are spinning in the correct
direction before proceeding .
After confirming that the brushless main motor is operating in the correct direction, and you have disconnected
the battery, reconnect the tail motor to the 2-in-1 control unit . Then, re-installed the main rotor blades in the blade
grips using the mounting bolts/nuts .
Your Blade CP Pro 2 is now ready to fly with the optional brushless main motor power system. Be sure to take
extra care when making the first test flights with the new power system as it can offer a significant improvement in
power over the stock brushed main motor power system . Also, be sure to take your time to re-adjust the tail rotor
proportional mix and gyro gain as necessary in order to maximize performance with the brushless power system .
