We have built and bought different drone platforms since 2012. Much has changed in that time as companies come and go, new capabilities emerge, and our techniques improve. Currently we are on Mark 7, a custom build hexacopter based on power and frame kits from DJI. In testing drones Mk 1-6 we developed a set of requirements which are described in memo 40. See memo 52 for a summary of recent testing and our motivation for the current design.


Payload Mounts

We typically mount the payload (transmitter, filters, antenna) beneath the drone. Most of the time we use 3D printed plastic. It is lightweight and rigid. Solid model files are here.
