Chill,
I'm with you, perhaps hand swing a four cylinder with a two bladed prop, but a six with three blades , no thanks!
Fortunately for me covered this in my training, with the key ingredients also being two people and plenty of chocks!
Is'nt there half a dozen charter companies and at least three maintenance hangars within walking distance of where this accident took place, all of which have battery carts. If your stuck in the middle of nowhere with no options improvise, but if you have access to facilities, walk the 50 metres and use them.
A little knowledge is a dangerous thing.
Thankfully no major physical injuries . HH.
PS: who is/was crash test dummy?
