No surprise that arrival proved timely, DHL being operated by Deutsche Post in the UK, where if it works it's probably German. One problem with the kit-built people-carrier is that it is about where the PC was when Jobs and Gates sold stuff from their garage; user information being much like playing a game of Cluedo.
I last worked with larger U13 motors that came with stub cables, whereas this has the 'Full Monty' attached. There are (very few) motors out of there with built-in ESCs and you have to wonder whether things will go that way, just as computers once had pop-in circuit boards and no longer do in order that the average chimpanzee can use one.
Like the gaming chips that my son prefers to dad's shit, however, these things all run hot given the current and are finned like the motorcycle cylinders of my youth. We could park the ESC next to the motor and open that up to wire it direct, though that would invalidate the warranty. We could also mount them on the centre-section so as to conceal the workings in a fancy dome, just like those guys spending millions of OPM (other people's money) on speculative air taxis.
Pays at this stage to stick to the knitting tho' and mount the controllers some place where there's an ample draught from the propeller, which to my mind is about where I've put it ~ if in doubt, use a half-way point. Bear in mind too that these cables would normally run down the tubes, whereas that would be silly on a prototype. It's the reason Jetson took a whole year and a lot of money to prepare a vehicle for sale... and they recently flipped from a kit offering to an ex-works strategy, doubtless in view of the potential cock-ups in assembling something more complex than IKEA's MALM.
Whatever happens it looks like we do not need any extra lead-length on the batteries and in fact we've more cable than we need: an embarrassment of riches. We do need thought to know which of the finer control-cables is which, one being longer than the other. Motors and controllers used in robots or cars require a feedback loop that allows them to work accurately at lower speeds, tho' drones use one-way logic to let the motor do its thing. One of said cables is therefore redundant, but which?
I say Professor Plum, with the soldering-gun, in the Hall-effect.
