Hi @Vinny,
Regarding Q2, each material has a constant called the temperature coefficient of resistance that symbolizes the resistance change factor per degree of temperature change. So I was wondering if your team was familiar with the temperature coefficient of the drone frame at any given Celsius. If not, then that's fine. The answer I got from you is enough.
Also, thank you for pointing out the LiPo concern. We will have to design a cooling container for the battery.
