The md4-200 is a VTOL AUMAV (VTOL = Vertical Take Off and Landing, AUMAV = Autonomous Unmanned Micro Aerial Vehicle).

For lowest weight and highest robustness we have designed the drone completely in carbon fiber. This carbon mono frame is also a perfect shield against electromagnetic interferences.

The outstanding AAHRS (Altitude and Attitude and Heading Reference System) uses the following sensortypes: Accelerometers, Gyroscopes, Magnetometer, Airpressure, Humidity, Temperature.

By means of our synchronized, brushless direct drives (transmissionless) the noise level is very low (rpm < 2000, noise < 63dBA @3m). These propulsions recover from stall and overload conditions even at flight time.

The optional GPS provides position hold and autonomous waypoint navigation. 

The onboard flight recorder (microSD card) permits a post-flight analysis in real-time.

With the downlink decoder we provide all important data at the base station (battery state, altitude, attitude, position, flighttime...). For best pilot support we have implemented a talking audio response system (no need to look at a display).

Security features prevent from crashing - autonomous landing on low battery or missing radio signal.

Depending on payload, temperature and wind the vehicle achieves up to 20 minutes of flight time.
