iflyjax Exemption No. 12669

Regulatory Docket No. FAA−2015−1156 update

In the interest of being in full compliance with curret FAA UAV regulations, I would like to add the 

following 2 aircraft to my existing Section 333 exemption.

dji Phantom 3 Pro

dji Inspire 1

Both of these UAV's have significantly improved dependability and safety. I believe it to be in the best 

intrest of all involved to add these to the list of qualified aircraft available to iflyjax LLC exemption.

Improvements include:

ROTOR DESIGN

The all new 13 inch quick release rotors are built with the unique DJI "Z-Blade" design. They have been 

reinforced with new carbon fiber compound material to ensure excellent performance with increased 

stability.

CURVED MAGNETS

Brushless motors pioneered by DJI are now the standard in the multirotor industry. But the Inspire 1 

takes the next step in brushless development by integrating curved magnets that fit flush around the 

edge of each motor. Although much more difficult to produce, these magnets eliminate airflow gaps 

within the motor, greatly increasing efficiency.

SINGLE-WIRE DESIGN

Several strands of copper wire have been replaced by a single, dense strand. Reducing the wasted space 

between wires results in more copper within each motor, providing more power and less resistance. A 

centrifugal pump increases airflow inside the neat, tight copper windings dissipating heat much faster 

while greatly increasing the life of the motors.

NEW ESCS

The revolutionary Electronic Speed Controllers (ESC) with sinusoidal drive replaces the square wave 

drive of traditional ESCs redefining the whole drive system. The patented algorithm in the ESCs have 

been tuned and customized specifically for the Inspire 1 offering features such as closed loop torque 

control and distinct functional redundancy with the highest efficiency and the most reliability.

INTELLIGENT POWER MANAGEMENT SYSTEM
A fully integrated intelligent battery powers your Inspire 1 and virtually manages itself.

When in flight, your remaining battery power is shown live, letting you know how long you can continue 

to fly. Advanced algorithms calculate the distance of your aircraft and estimated time to return home, 

letting you know when it’s time to fly back.

POSITIONING

As it flies, the position of your Inspire 1 is constantly updated and recorded using a high-strength, 

intelligent GLONASS + GPS system. This dual positioning system enables higher precision and quicker 

satellite acquisition, allowing you to see where the aircraft is on a live map and giving it a point to hover 

at when you release the controls.

MAIN CONTROLLER

This is the "brain" of the entire system, receiving thousands of bits of data every second and translating 

that data into action as you fly. The Main Controller tells every part of your Inspire 1 what to do, 

calculates environmental conditions in real-time, and ensures that the aircraft responds to your control 

commands instantly.

IMU

Automatically keeping the Inspire 1 stable and steady during flight only looks easy, as DJI’s advanced 

Inertial Measurement Unit (IMU) handles everything. The IMU incorporates both a 6-axis gyroscope and 

an accelerometer to monitor miniscule changes in tilt and movement. This allows the aircraft to 

compensate and adjust immediately, holding its position at all times.

FAILSAFE

All of these features combine to put your Inspire 1 on autopilot when needed. If the battery runs low or 

connection with your remote controller is lost, the Inspire 1 uses its positioning system and smart flight 

technology to return back to you.

THE COMBINED VISUAL DATA AND SONAR WAVES

DJI built the Vision Positioning System from the ground up, customizing it to meet the rigorous 

requirements in place for anything that handles position holding on our flying platforms.

This system combines visual data and sonar waves in a single unit, detecting both variance in patterns 

on the ground and current altitude. With this information, your Inspire 1 can hover in place and 

automatically raise or lower its arms as you liftoff or descend to the ground.

THE CPU CHIP

But the sonar and visual information is just one half of the fully integrated package: processing this 

information is handled by a dedicated CPU chip. This chip takes in feedback and outputs data in 

real-time, and is intelligent enough to distinguish between objects and ground patterns. All of this data 
is given to your Inspire 1’s flight controller, which in turn communicates with the entire aircraft.
