Fully redundant twin engine design


VelosV2 core innovation is its twin engine fully redundant design. There is a set of every major component including the main motors, batteries, electronic speed controls (ESC), belts, and gears. VelosV2 has new enhanced features and accessories. Unlike most UAV helicopters that are based on common hobby grade helicopters, we chose to design the Velos UAV from scratch with three main objectives.

Safety – Efficiency – Reliability

Our patented highly innovative drivetrain-gearbox renders Velos UAV the only UAV helicopter in its class with the ability to tolerate a complete failure of most major components allowing it to safely land and protect its payload and surroundings under those circumstances. The system automatically isolates the faulty part without introducing additional drag to the operational part of the drive-train.

Any or all of the below listed types of failures can be tolerated by the Velos UAV’s mechanics while these would lead a normal UAV to a crash

Motor failure, broken belt, gear – one-way bearing failure, Burned ESC, main battery failure, BEC failure, servo failure.

Second Version (V2) of Velos UAV

The Second Version of Velos UAV, VelosV2  has enhanced new features:

  • New blades (V3) are specially designed for the specific helicopter, based on the data from the first 2 generations. Their revolutionary design leads to higher lift with lower battery consumption.
  • The helicopter fuselage has new more aerodynamic design and it is built from new lighter components resulting to lower weight, higher speed/range and improved waterproofing of the mechanics.
  • The new skid pads allow a bigger space for different and larger payloads
  • New more efficient electric motors especially designed for VelosV2
  • Most of the components are now made from carbon fiber and are stronger and lighter

Velos UAV mechanics are extensively tested and proven to be extremely reliable and maintenance free thanks to the ingenious design. Having clocked more than 10000 hours in the air there are no hidden surprises and our UAS just performs flight after flight.


Payload Integration

Velos UAV  is a professional UAV helicopter designed in way that it can be easily adapted in a variety of different applications. The unique payload rail system provides plenty of flexibility and free space thus allowing almost any possible payload to be mounted on the helicopter in a fast, easy and reliable way. Furthermore, it is very easy to switch between different equipment, e.g. remove a gimbal and add a thermal camera or a LIDAR in few minutes.

In addition, you can add simultaneously more than one payloads. For example, in the front of the payload rail we can mount two small cameras like an FPV day or night and a thermal camera and we still have the most part of the rail available for a gimbal, LIDAR sensor, delivery box, magnetometers, a powerful flood light or whatever you may need to attach.

This is possible as the helicopter’s payload rail has a total length of 55cm (21.5inch) and there are 14 sets of extruded bases along its length. They are placed along the rail every 4cm and there are M4 threaded holes in all of them.  With 28 in total different locations for mounting payloads it is easy to integrate your payload in the way you wanted to be or even combine different payloads.

With all that flexibility available the only limit is your imagination.


We are using customized firmware for flight controller, that is specialized for helicopters and is optimized through thousands of flight hours. This is compatible with all the ardupilot supported ground control software like mission planner, Q ground control, UgSC and many others.
