HMF-U580/PixHawk Hexacopter 

The HMF U580 Pro is a professional level quadcopter frame that has the unique ability to fold 

the arms down for easy storage and transportation. The HMF U580 Pro also includes a set of 

retractable landing gear too, this means that when using a gimbal attached to the anti-vibration 

mounting booms you can retract your landing gear in flight for a full unobstructed view of the 

action. 

The anti-vibration gimbal mounting tubes are also compatible with many of the most commonly 

used gimbals such as Tarot and DYS types. 

The HMF U580 Pro features precision CNC aluminium motor mounts with carbon fiber plates 

designed to absorb any vibrations your motors may produce. These motor mounts are also 

compatible with basically any multirotor motor such as 2212, 2216, 3108, 3110, 3508, 3510, 

4108 with 10-15inch propellers. 

The central plate is designed to be used with many of the popular flight controllers such as APM, 

Pixhawk, DJI, Zero, and with the PDB central plate, wiring all of the power between your ESC's 

is a breeze.

OVERVIEW 

The benefits of the Pixhawk Flight Control Unit (FCU) system include integrated multithreading, 

a Unix/Linux-like programming environment, completely new autopilot functions such as 

sophisticated scripting of missions and flight behavior, and a custom PX4 driver layer ensuring 

tight timing across all processes. These advanced capabilities ensure that there are no limitations 

to your autonomous vehicle. Pixhawk allows existing APM and PX4 operators to seamlessly 

transition to this system and lowers the barriers to entry for new users to participate in the 

exciting world of autonomous vehicles. 

The flagship Pixhawk module will be accompanied by new peripheral options, including a digital 

airspeed sensor, support for an external multi-color LED indicator and an external 

magnetometer. All peripherals are automatically detected and configured. 

Note: Pixhawk is a PPM-input autopilot, which means that it gets RC input from a single cable 

to the receiver, either via the PPM port, the Futaba S.BUS port, or the special satellite receiver 

port for Spektrum gear. Most modern RC receivers (and all those sold by 3D Robotics) allow for 

PPM output, but some, such as non-S.BUS Futaba receivers, do not. If your receiver does not 

support PPM output, please add a PPM encoder board option to your order below.
