More information


Aircraft modifications

Nose boom



A bubble window with operator location and navigation telescope at the right front-side of the cabin.


Cabin floor: 1 x W2.06 m x L0.52 m and 1 x D0.48 m
Cabin roof: 1 x D0.40 m and 1 x D0.15 m at the back ; 1 x D0.15 m at the front

Hard points

6 hardpoints in the middle of the fuselage floor for external loads up to 200 kg. It is planned to install a radom for the protection of sensors.
Each fuselage side provides 3 hardpoint pairs below the cockpit area for a load of max. 50 kg (e.g. SLAR).
Below both wings, not within the area of the propeller, there are hardpoints for 100 kg each.


4 in total.

Additionnal systems

Additional mounting rails for measuring equipment in the cabin.
Tubes in the wing and the fuselage for measuring and supply lines.
Breathing oxygen system for a max. of 5 persons for flights lasting up to 5 hours in a flight altitude of up to 25000 ft.

Acquisition systems

Onboard data recording system. Telemetrie-link to a ground station on development.
