BASIS FOR THE AMENDMENT TO EXEMPTION #12113

KADOO AERIAL received a 333 Exemption # 12113 to operate an X-UAV Skysurfer MAX to 

conduct aerial photography and videography, inspections, and monitoring. Upon testing and research, I 

Cody A. Porter Owner/ Operator of KADOO AERIAL have determined that the X-UAV Skysurfer MAX is 

not suitable for future application at KADOO AERIAL, due to the design of the aircraft, it was not able to 

carry the aerial camera we were going to attach for inspections. I am amending that it be removed from 

#1 of Conditions and Limitations granted to KADOO AERIAL Exemption #12113. I would like to amend to 

add two addition UAS that will be replacing the X-UAV Skysurfer MAX. KADOO AERIAL has not 

registered the X-UAV Skysurfer MAX so no commercial operations have or will be conducted. KADOO 

AERIAL is requesting this amendment to operate two additional UAS. The KA X800 Multirotor and 

Skywalker 1900.

UAS that KADOO AERIAL is seeking to add upon removal of the X-UAV Skywalker MAX

The first UAS I am requesting to add to KADOO AERIAL Exemption #12113 Conditions and Limitations 

part #1 is the KA X800 Multirotor. The KA X800 Multirotor has an overall flying weight of 5.0 pounds 

with a total width of 42 inches. Additional information is attached below.

The second UAS I am requesting to add to KADOO AERIAL Exemption #12113 Conditions and Limitations 

part #1 is the SkyWalker 1900. The SkyWalker 1900 has a total flying weight of 4.2 pounds. The wing 

span is 75 inches. Additional information has been attached below.

All operations that were approved for the X-UAV Skysurfer MAX will be followed for the KA X800 

Multirotor and the Skywalker 1900 including the safety and maintenance checks upon approval of this 

amendment. 

CONCLUSTION 

KADOO AERIAL is requesting an amendment to #1 of the Conditions and Limitations issued with 

Exemption #12113 for KADOO AERIAL. KADOO AERIAL would like to remove the X-UAV Skysurfer MAX 

and replace it with the #1 KA X800 Multirotor and the #2 Skywalker 1900 in part #1 of Conditions and 

Limitations for Exemption #12113.

Thank You,

ADDITIONAL INFORMATION

I believe allowing KADOO AERIAL to amend and add these UAS to the Conditions and Limitations part #1

of Exemption #12113 will allow for even safer operations because they have the ability to carry the 

ARDUPILOT flight controller board giving KADOO AERIAL the ability to Geo Fence which will allow 

KADOO AERIAL to set a predetermined distance from the operator that will automatically return to the 

predetermined launch site if the UAS reaches a certain distance away from the operator. And the 

ARDUPILOT will also allow you to program points of no fly zones and return to a safe fly zone and alert 

the operator that the UAS was near a potential no fly zone boundary. The ARDUPILOT also has a built in 

barometer and optional attachment of a sonar device for height above ground. Which will allow you to 

set a predetermined height and will alert you if you are near that height at any time. The ARDUPILOT 

also has the ability to measure real-time data and send it via telemetry to a ground station that will 

audibly play alerts and warnings and will return to the launch site if a failure were to occur.
