More information

The under cabin bay is the main for payload installation. This bay volume is 5.15 m3. Maximum weight of payload installed there is not more 900 kg.
The under cabin bay has 3 zones for payload installation: Name ( number ) of bay / Bay volume [m3] / Weight of installed payload [kg]
- Bay 1: 2.052 m3 and 360 kg max payload
- Bay 2: 1.963 m3 and 430 kg max payload
- Bay 3: 1.135 m3 and 100 kg max payload

The fuselage bay has four zones for payload installation:
- Bay 1: 0.315 m3 and 60 kg max payload
- Bay 2: 0.600 m3 and 80 kg max payload
- Bay 3: 0.580 m3 and 25 kg max payload
- Bay 4: 0.380 m3 and 30 kg max payload
