Thanks Jab7252, I read your “light reading” - and will never approach my Savannah again without my acid-resistant protective gloves! But, seriously, there was obviously something wrong for a Jabiru to spontaneously ignite. In this particular situation, even though the Jabs were used fairly frequently for student training, the standard batteries were often unable to start the engine. Hence the need for leaving them on a charger. Maybe there is a need for some guidance on best battery or best way to maintain adequate charge.
