I have not read this full thread but I know from building our VeFoil (flying jet surfboard) that standard RC (remote control) wire sizing just does not cut it for safety. There is a huge difference in running something remote controlled without your being attached to it VS something you are strapped to thousands of fee up in the air.
I had to meed Canadian and US Coastguard wiring regulations and this will be an eye-opener for most of you still thinking 10awg, and even 8awg are heavy duty.
I am not trying to be negative here just want to make you think twice about your wiring. 400+ degrees wires that are desoldering, and or a flare up on a lipo if your body gets exposed to those while flying gives you two options… both do not end well. I cannot stress enough the importance of certified low awg wire, and heavy duty connectors likely WAY heavier than you are using now. An extra day worth of upgrading and a $100 more in parts is no brainer.
