Product description

The newest MULTIROTOR-product is called "Recon One" and is the result of a consequent development, many years of drone

construction experience and typical customer needs concerning a Surveillance UAV with special lengthy flight duration:

The focus is on the enormous flight time of 50 - 90 minutes depending on the loading and use concept.

This is possible through latest drive dimensioning. Unusual is the outstanding flight stability of the MULTIROTOR Recon One, which

you did not know from comparable products with slow turning rotors.

Decisive is the innovative and prizewinning MULTIROTOR flight-control of the 4th generation, which corrects the flight position 512

times per second. Thereby missions are also possible with bad weather conditions. The handling is very easy and safe.

As camera sensors RGB-Zoom cameras and infrared or thermal image detectors are provided.

Finished RTF Solutions (ready to fly) are as upgrades for Defense- and survey missions (Surveying) available.

The system is fully scalable and therefore provides the ideal base for demanding UAV applications according to your wishes.
