Good evening everyone.
I read the word "mathematics" and then I got curious.
I wanted to reread a message that I hadn't given particular weight to because I hadn't fully understood its meaning and it seemed off topic, perhaps even useless.
However, I thought I had misinterpreted the content.
But is it "mathematics" with a capital "M" or mathematics with a lowercase "m"? Ahahahahaha!
My tone is joking, please don't let anyone take it badly, but I want to be precise.
I reread it and asked myself: "isn't he really commenting on the contents of an electronic item sold on Aliexpress?"
"Aren't you really commenting on the fact that some data provided by sellers on Aliexpress is not very reliable?"
Yet the more I read it, the more I realized that there was no other explanation.
Do we really evoke the word "mathematics" to comment on the section of electrical cables based on current absorption?
Is there a need for special calculations for quite obvious things?
Anyone will have seen, inside a car, the section of the cables and the value of the fuses, anyone will have made a comparison and realized that for 320 amp. (in DC supplied continuously) much larger sections would be needed.
What a sensational find!
Anyone will have seen a table with the cable sections in mm2 or AWG and the related electrical currents.
Are we talking about this exactly?
But even before the cable sections, the connectors are already giving the warnings. The Tamiya connector reaches a certain current capacity then other types of connectors are needed.
In the last two messages I explained twice why I included those links. This alone, in my opinion, should be enough.
I expressed my opinions (certainly questionable) on brushed motors, ESC and more.
Once the choice was based on Roy's advice (which I share) I expressed my personal opinion (this is also debatable) on the casings of electronic devices in general and I showed what I meant with the images of the links.
However, at that price, I would still buy those ESCs if I needed them, even if they don't meet the specifications declared by the seller in the slightest.
The wires are large enough for the currents that I measure or estimate are actually flowing in a specific situation (certainly not 300 amps, it makes me laugh just thinking about it).
In any case that section would be protected by the fuses that I use, based on their threshold.
The price is low and don't worry if they break.
Of course, it's not just the cables that have to withstand the passage of current, there are the tracks, the individual electronic components, etc. etc.
Will there also be a difference between an apparatus that costs 5 euros and a similar one that costs 150?
Furthermore, if you remember, my first (questionable) choice was for the Graupner Gra2880. There are less expensive and more expensive ones.
Well what can I say? If this had been the topic of the topic, perhaps I would have also wondered why sellers indicate these capacities in amperes.
Who knows if they refer to measurements of transient or peak passages or simply threw in a value at random.
This wasn't the issue.
Steve asked some pointed questions.
Some like Roy, RodC, Scotts, Terry have given precise indications with useful information content.
Instead, I can't understand what use it could be to say that Ebay has many types of engines for sale and a person can choose what he wants.
