They mention that thermal cycling is a big issue. It get s super cold at night. Eventually some soldering joint fails. Other issue is the CPU is not rad hardened so there might be a fault. Also a mechanical failure like the blades breaking or tipping over.
- olex 6y agoI imagine the batteries aren't liking the thermal cycling a lot either - they are normal (albeit rather high-quality) 18650 Li-Ion cells, that are usually quite sensible to storage and operating temperatures and will tend to lose usable capacity and power output after being stored and used in the cold.
- Tsiklon 6y agoI recall reading somewhere the majority of the power consumed by the helicopter is used for heat to prolong the life of the battery cells.
