    Yes. What you all will miss even more than the noise is the vibration.

    I'm not sure if Jedi missed the double entendre or nailed it...

    Speaking as someone raised in Los Angeles, I can say I'm pretty sure he nailed it.

    ...and had to hand swing a prop, sometimes standing in snow and hoping the idiot in the cocpit knew the difference between cracking the throttle and half throttle.

    Sounds like a gearbox or something clunking. Is it direct drive?

    The shop video indicates direct drive, the noise seems to be erratic. Also looks like they have a pile driver working to extend the docks.

    Background noise came from a variety of sources.
    They did the test flight under the approach to Vancouver International Airport and a helicopter flew past - at low altitude - during the Electric Beaver test flight.

    The EAA reporter got it wrong. The flight used Lithium ion, not lead acid. In the article the EAA linked to as a source, the founder/CEO stated:
    "The demonstrator Beaver carried 135Wh/kg lithium batteries – a relatively low-density battery that, while close to aviation standard, generally lacks sufficient power-density for viable commercial operations, McDougall says."

    I think this has been mangled because he stated that they used a "tried and true" (CEO's words) battery on their first flight instead of a more powerful one, and people assumed this meant lead acid rather than a lower density lithium ion.

    A Google search for "Harbour Air" "lead acid" doesn't give any notably reliable sources that connect the two.
