Hello ModalAI,
what are the performance specs for the Sentinel Drone? 
Specifically those which are not mentioned on the Sentinel webpage:

•	Cruise speed (normal operation)
•	Max horizontal speed
•	Max wind speed for safe operation
•	Max range
•	Max altitude MSL
•	Max rate of climb
•	Max rate of descend
•	Max gross weight (empty weight + battery + max payload) – Sentinel Drone without 5G modem

Thank you,

We have the following on [our datasheet](https://docs.modalai.com/sentinel-functional-description/#flight-specs), the rest are un-measured

* Cruise speed (normal operation)
> Not on datasheet, but as a development platform this is configured by the developer via standard PX4 configuration

* Max horizontal speed
> "5m/s per PX4 setting"

* Max wind speed for safe operation
> Max not measured, but tested at 30MPH gusts

* Max range
> Not measured

* Max altitude MSL
> "122m per PX4 setting"

* Max rate of climb
> Not on datasheet, but as a development platform this is configured by the developer via standard PX4 configuration

* Max rate of descend
> Not on datasheet, but as a development platform this is configured by the developer via standard PX4 configuration

* Max gross weight (empty weight + battery + max payload) – Sentinel Drone without 5G modem
> 1347g (1011g without battery), 1kg payload capacity

Thanks, Chad.
Any chance we can get some better numbers or estimates ?
The PX4 related items are just user-defined and don't correspond to the actual physical capabilities of the drone, which we would need to categorize the UAS into a safety class.

We really don't have anything better, sorry. The Sentinel is really intended to be a development platform, and not support any mission critical activities.
