Polar Express


Hate at first sight when it came to this motor, mainly because its axle extends beyond the base requiring a shim like this and because there is insufficient depth of thread to play with before the bolts impact the windings. Neither an issue with the U13 model a few grades up ~ this a peril of buying online, its bulk returns and the carbon emissions that go with it.

Does bring proceedings to a halt as I need to know if Loctite will secure that washer or whether I'll need to shop for superglue... which is not the priority come Christmas Eve. In retrospect I should have opened only one set of packaging so the goods could be swapped for more powerful equipment; but like Scott in the Antarctic we're beyond it, and it's do-or-die with a 24-volt set-up.

Looking ahead therefore I check the weight of the payload viz. completed transporter including mannekin. It comes to 5.90kg or thirteen pounds, which is fairly remarkable for what is practically a two-third scale iteration. At 75% we've theoretically fourteen kilos of thrust, though that's well beyond what you'd want thrust settings to be in the hover. There's still the weight of the drone to consider too, though it should come in well under the payload.

Worst case we'll dump the mannekin, halving the payload at a stroke. We'd all still get the picture knowing the power can be upped. Whichever form of transport we use ~ whether car, aeroplane or all else ~ started off with power that was a fraction of what it would later become. And so now it must be time for old Mr Fezziwig to clear the factory floor, don his best breeches and set the tables for an evening of merriment... and God bless us, one and all.
