4-in-1 Control Unit Description, Arming and Adjustment (continued)
Below are tips for use and adjustment of your 4-in-1 unit to achieve the best performance of your Blade CP.
While each Blade CP model is test flown at the factory with adjustments made to both the gain and proportional
trimmer pots, further adjustment to these trimmer pots may be required based on the type of battery used, or
preference and flying style of the pilot. However, before any changes to the trimmer pots are made, test flights will
need to be conducted. Use the following check list for your first and all subsequent flights:
• Each time before you fly you must always turn on the transmitter power first before connecting the flight battery
to the 4-in-1 unit. Also be certain to fully extend the transmitter antenna before flight.
Note
: The receiver antenna exiting the 4-in-1 unit will be coiled around the landing skid struts. We have made
many successful flights indoors and out (some nearly out of sight) with the antenna coiled this way and did not
experience any problems with performance of the radio system. If you are tempted to uncoil this antenna, please
be sure to route it safely away from all moving parts and electronic items. Remember, due to the relatively small
size of the Blade CP, you will not want to fly it very far away from yourself in order to keep proper orientation.
•
Both the throttle stick and throttle trim need to be in their lowest possible position in order for the
unit to arm.
The “idle up” flight mode switch must also be in the “normal” position with the switch toggled
toward the back of the transmitter for the unit to arm.
• 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.
• Once confirming the transmitter has been turned on and has an adequate level of battery power as displayed by
the LEDs at the top of the transmitter, it is now safe to plug the flight battery into the 4-in-1 unit.
• With power applied, the 4-in-1 unit status LED will blink red, then blink green. It is extremely important that
during this time of calibration the helicopter is not moved or swayed in order for the gyro to properly
initialize. If the helicopter was moved or swayed during this time, unplug the flight battery and repeat the
initialization process.
• When the status LED becomes solid green, the unit is armed and ready for flight. Use caution as both the main
and tail rotors will now run with throttle stick input. For safety, once the unit is armed the main and tail motors
will not run with the throttle stick and trim in their lowest positions. Do not advance the throttle stick until you
are clear of the rotor blades and ready to fly.
• Once you have placed the helicopter in a safe area to fly, free of obstructions, and are clear of the rotor blades
you can safely power up the model. Advance the throttle stick slowly, noting the direction of the main and tail
rotor blades as the rpms increase. The main rotor blades should spin clockwise when viewed from the top, with
the tail rotor blades spinning counterclockwise when viewed from the right- hand side of the helicopter. If either
set of rotor blades is operating in the wrong direction, unplug the battery, then simply reverse its motor wire
plug polarity on the 4-in-1 unit.
• Once the tail rotor has begun to spin, and before lifting off, it is best to check that the tail rotor is responding
properly to transmitter inputs. When inputting a slight amount of right rudder, the tail rotor rpms should
increase, pushing the nose of the helicopter to the right. If you are on carpet, grass, or an otherwise uneven
surface, be very careful not to allow the helicopter to catch the vertical tail support when testing the tail rotor
control on the ground or during liftoff.
• If both rotor directions are correct, and the tail rotor is responding properly to rudder inputs, you can now lift
your Blade CP into hover to check gyro gain and tail rotor proportional mix.
