Dear Sir or Madam: 

March 1, 2016 

Pursuant to Section 333 of the FAA Modernization and Reform Act of2012 and 14 C.F.R. Part 11, Natalie 

Contracting, LLC seeks to modify its current exemption to add additional sUAS aircraft types to Exemption 11354. 

Natalie Contracting, LLC. Seeks to add the following UAS to its fleet operating under Exemption 11354: Homebuilt 

Hexacopter 550 

Aircraft Make and Model: Hexacopter 550 

Configuration: Hexacopter 

Aircraft Performance/Specifications: 

• Ground Control Station (GCS): The aircraft will be primarily controlled through the use of a handheld 

console or laptop via 900 MHz, 2.4 GHz, or 5.8GHz. 

• Lost Com: Aircraft will autonomously return to the launch location and safely land. 

• Emergency Procedure: Should the need arise the aircraft can be commanded the tablet GCS to safely land 

immediately or return and land at the launch location. 

• Power Supply: Lithium polymer batteries 

• Dimensions: frame arm 350mm, center frame diameter 240mm, landing gear height 

320mm 

• Maximum Speed: 8 m/s (15.5 knots) 

• Normal operating speed: 5 m/s (10 knots) 

• Weight without payload or battery: 2.6kg

By having the option to utilize this additional aircraft types under our existing exemption, we would be able to 

improve safety since this aircraft has controllability with one motor inoperative.
