Re: Materials in Support of Petition for Exemption Pursuant To Section 333 

of the FAA Modernization and Reform Act of 2012

Dear Sir or Madam:

Petitioner, Unmanned Aerial Systems Development, Inc., is a Massachusetts 

corporation doing business as UAS Development (“UASD”). UASD has previously 

submitted a comprehensive packet seeking exemption for commercial operations of 

their unmanned aerial vehicles (UAVs) for the purposes of cinematography work and 

support services for advanced research of UAV systems and integration. Our 

petition has been assigned the docket ID number FAA-2015-0192.

The material submitted herein is in response to your Request for Additional 

Information dated June 4th, 2015 and sent to us by email from Nia Daniels, Program 

Analyst with the FAA. The request sought comprehensive information regarding the 

UAVs that UASD intends to use in its proposed commercial operations. 

UASD is currently seeking authorization for two distinctive and separate UAV 

Airframes. Specific data for each is outlined in the following page(s) and additionally 

attached materials to this filing.

Should your office require additional information, please provide specific 

direction as to materials not covered in this document, or within the previously 

submitted petition and operations manual.

Sincerely, 

Jeffrey Adams

Co-Founder, President

UAS Development, Inc.
The initial and primary aircraft proposed to be used by UASD is the UASD 

CorbonCore1 (N-243JM). The aircraft is a rotorcraft powered by 8 electric motors in a 

quad-copter configuration. The airframe is built from parts supplied by the 

manufacturer, Carbon Core, Ltd. (UK) and fitted with third party components including 

power supply and distribution, flight control systems, guidance (GPS) controls, 

payload gimbal (operated by a separate radio frequency transmitter) and landing 

superstructure. As such, there is no singular manual as prepared or supplied by the 

airframe manufacturer.

 


                        Airframe:         CarbonCore Cortex

                        Dimensions:    Length: 38.25 inches

                                                Width:   38.25 inches

 Height:   24.0 inches

 Empty Weight (with batteries): 13.6 pounds

 Maximum Gross Weight (with payload): 44 pounds

                        Motors (8):        KDE401XF-400

                        Propellers (8): T-Motor 16: x 5.5 balsa cored carbon fiber

                        Battery: 10 Ah 6S lithium polymer

The CarbonCore1 airframe is intended for operations in high resolution aerial 

filming and cinematography, and as such, the typical payload will include: one (1) 

production grade digital camera and lens package, and a multi-spectrum, frequency 

switchable transmitter for image preview by the ground crew operating the gimbal. 

Comprehensive information regarding frequencies and electronics operating 

parameters can be found within the contents of the original petition material and 

operations manual submitted in our initial filing.

The second airframe we are seeking to incorporate in our standard operations is 

a smaller, mass production unit, a Solo from 3D Robotics. The intent of this airframe is 

for service operations that do not require the robust operating capabilities of our 

primary airframe, as well as for initial scouting and mission planning. The vehicle will 

also be employed in training capacity of our operations personnel. We have submitted 

the manual from the manufacturer for specifics on this airframe along with this filing.

	 	 Airframe:       	 Solo (3D Robotics)

	 	 Dimensions:     	 Length: 18 inches

	 	 	 	 	 Width:   18 inches

                                               	 Height:   10.0 inches

	 	 Empty Weight (with batteries): 	 	 3.3 lbs. (1.5 kg)

	 	 Maximum Gross Weight (with payload): 3.9 lbs. (1.8 kg)

	 	 Motors: 880 kV

	 	 Propellers: 10′′ diameter 4.5′′ pitch self-tightening

	 	 Flight battery: Lithium polymer 5200 mAh 14.8 Vdc

This airframe is not yet assigned an FAA registration “N” number. Filing will be 

undertaken as soon as all required documentation is available from the manufacturer.
