@ Romulus [quoteWhich other systems should have "proven substitutes"?
All of them?][/quote]
ALL other "innovative" technologies that we are aware of in this particular aircraft construction, are well proven in plenty of other applications.
A "decision" was made to fit an unproven, known to be unstable battery and this was compounded by linking it to a "revolutionary, patented" controller/charger.
Are you REALLY suggesting that this was a well-thought out, well-engineered, safe system that met the SPECIAL CONDITIONS applied to it?
read the Forum ROE....don't know what your gripe with me is, but play the ball, not the player, thank you.
