For temperature and ingress protection info, please refer to the technical specs section:
No hotswap protection. Do not mate or demate Smart Dovetail while the aircraft is powered.
If the payload has even modest capacitance or other inrush current the connector contacts on both aircraft and payload side will be eroded.
We have tested this payload up to a speed of 15m/s, climb rate of 4m/s, and descent rate of 3m/s. There has been no significant performance testing past these limits. Refer to the performance section of the Astro wiki for more information.
