Re: Docket No. FAA-2015-2313
U. S. Department of Transportation Federal Aviation Administration

Dear Mrs. Robeson,
Since filing the FAA Petition for Exemption, I have changed my choice of a multi-rotor's from the “MicroKopter” to the “Tarot 680Pro”. The Tarot 680 Pro is identical in size and weight to the MicroKopter listed in my petition but is powered by more modern and sophisticated flight and planning software. Below list shows spec ification for the Tarot 680Pro:
TAROT 680PRO six axis aircraft designed by TAROT company, with a number of patented technologies. TAROT 680PRO has a convenient folding design with low center of gravity and stable flying design. The 680PRO is equipped with high strength matte gold process of composite PCB circuit, integrated PCB board connection to power supply, electric adjustable connection more efficient, safe, providing adequate space for various flight control system. The Dongli 3K hollow pure carbon carbon fiber tube (non 3K glassy carbon tube) all CNC processing. Design standards higher than similar products. Model 16MM carbon tube folding seat widened 3 point support, to prevent cracking breaking effect, contact surface increases and the carbon plate, the new anti skid design can tightly lock the better carbon tube. The new carbon tube fixed set of imported fiber reinforced nylon material,upper and lower using M2.5 ladder screw fastening, the diameter of M3.2 contact surface can make the PCB board and the arm fixedly connected. The new folding bipod whole independent design safety locking device, to prevent the impact force caused by the overall damage tripod contraction,aircraft. The new motor a new brushless electric adjustable mounting position, wire harness protection clamping, clamping type design easy to adjust the motor base level. From the angle of impact has strong double color eye-catching color appearance design, provide good visual direction for the body. TAROT 680PRO is especially suitable for monitoring,remote sensing, mapping, aerial observation, fire, life exploration, cable line, farm monitoring applications.
TAROT 680PRO: Full weight 2.76KG Hovering flight time 20 Minutes.
Diameter 695 MM Rotor size 10 inch carbon fiber propellerPropulsion 4S/620KV 4006 brushless motor TL68P02 Battery specifications: 14.8V 4000-6000MHA The Tarot 680Pro is powered by Pixhawk and is a very stable and reliable multi-rotor platform that has been previously approved by the FAA through through multiple exemptions:
Exemption No. 11889 Exemption No. 12315 Exemption No. 12171 Exemption No. 12720 Exemption No. 12206 Exemption No. 12177 Exemption No. 11998

Since filing for FAA 333 Petition for Exemption, I have purchased a Sensefly eBee fixed-wing aircraft and would like to include this UAV in the petition. The eBee is a light weight and reliable fixed-wing aircraft that has also been prev iously approved by the FAA through multiple exemptions including the Sensefly corporation (Exemption No. 11263). Below list shows specification for the Sensefly eBee fixed-wing UAV system:
Weight (inc. camera) Approx. 0.69 kg (1.52 lbs) Wingspan 96 cm (38 in) Material EPP foam, carbon structure & composite parts Propulsion Electric pus her propeller, 160 W brushless DC motor Maximum flight time 50 minutes Nominal cruise speed 40-90 km/h (11-25 m/s or 25-56 mph) Radio link range Up to 3 km (1.86 miles)
Since my original filing for Petition for Exemption, I have joined the Academy of Model Aeronautics and have been certified as a pilot for SkyCatc h. Please let me know if you have any additional questions.
Sincerely, Dave Spurlock
