WARNING: Stopping the motors while the quadcopter is still in 

 ight will cause the quadcopter to crash. Crash damage is not 

covered under warranty.

After landing, hold the motor stop button, programmed during the 

transmitter setup, to stop the motors.

If the quadcopter is less than 20 ft above the original starting 

altitude, hold the stop button for 1.5 seconds to stop the motors.

If the quadcopter is more than 20 ft above the original starting 

altitude, hold the stop button for 3 seconds to stop the motors.

To restart the motors, position the transmitter sticks

• Slide the fully charged 

battery in until it locks.

• Remove the battery by 

pressing the locking tab

and sliding the battery 

to the rear of the 

quadcopter.

• A green LED cycles around the motor pods counter-clockwise until 

GPS is acquired

• Once GPS is acquired, the front LEDs are white and the rear are green

• Intended for the beginner pilot

• Maximum distance of 200 m from the pilot

• A purple LED cycles around the motor pods counter-clockwise until 

GPS is acquired

• Once GPS is acquired, the front LEDs are white and the rear are purple

• Intended for the intermediate pilot

• Maximum distance of 200 m from the pilot

NOTICE: If the ChromaTM quadcopter loses GPS signal while  ying in either Smart or AP Mode, the LEDs will  ash rapidly for 2 seconds and then once every second. The quadcopter will 

default to a stable  ight mode with similar control response as AP Mode. Return Home will not function. Please familiarize yourself with the controls in AP Mode to ensure a safe return of 

the quadcopter in the event of GPS signal loss.

For information on additional  ight modes, see the online video at www.KnowChroma.com.

Pay close attention to the LEDs while  ying. If at any time the LEDs indicate

the  ight battery voltage is low, as shown in the LED reference guide, land the

quadcopter immediately and charge the  ight battery.

This aircraft is not compatible with the Blade ST-10+ Personal Ground Station Transmitter.

Fold the inner “T” sheet (A) around the

camera, with the metallic side facing away 

from the camera, so it covers the top, sides and 

back. DO NOT peel off the backing.

Peel the backing off the rectangular sheet (B). 

Wrap sheet B around the back of sheet A,

sealing the rear edges and holding the sides together.

The shield is removable and is held in place by the camera 

mount. The front and bottom of the camera are left unshielded 

to allow any RF noise to radiate out and away from the quadcopter.

Install the camera mount to the isolation bracket using the provided thumb screw and nut.

The included static camera mount is compatible with 

GoPro® HERO 3 and 4 cameras.

The Blade® ChromaTM quadcopter includes two 

adhesive-backed, metal-foil sheets to provide GoPro®

users with an extra measure of RF-shielding.

• Slide the assembled camera 

mount onto the pre-installed 

rail until it locks.
