3-in-1 Control Unit Description, Arming and Adjustment
The unique 3-in-1 Control Unit installed on your Blade™ CP Pro is a lightweight combination of main motor and tail
motor mixer, main motor and tail motor electronic speed controls and piezo gyro. The 3-in-1 unit also contains a
gyro gain trimmer pot, proportional tail rotor mix trimmer pot and status LED.
While each Blade CP Pro 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 performance of
the 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:
The following are tips for use and adjustment of your 3-in-1 unit to achieve the best performance of your
Blade CP Pro.
•
Each time before you fly you must ALWAYS turn on the transmitter power first before connecting
the flight battery to the 3-in-1 unit. Never connect the flight battery to the 3-in-1 unit before first
powering on the transmitter. Never turn off the transmitter before disconnecting the flight battery
from the 3-in-1 unit first. Also, be certain to fully extend the transmitter antenna before flight.
Note: The antenna exiting the receiver 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 Pro, you will not want to fly it very far away from yourself in order to keep proper orientation.

Both the throttle (left-hand) stick and throttle trim MUST be in their lowest possible position in order
for the 3-in-1 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.
