" The 3 channel FlySky Rx is, length times width,  35x22mm  and 13 mm in height "



Hi Juergen



Dimensional information, on all the principle components that have been discussed in this Thread, regarding 'FlySky' installations ...

... which are NOT just manufacturers-data & have been ACCURATELY MEASURED from the actual parts themselves ...

... have already been Posted, on a number of occasions, over the course of this 'FlySky' Topic.



The length, width & height dimensions, which you have ^^ Posted, DO NOT represent the correct sizes of the Receiver-board.

I assume you possibly might have quoted the dimensions of the BLACK PLASTIC-CASING illustrated ^^ above ...

... which the Receiver-board can be housed in.

As we know, Sound, D.C.C. or R.C. boards DO NOT require such plastic-casings & are simply used 'naked'.



" these components you've posted are really cheap "



I would say personally, that your choice of the word "cheap" is a bit unfortunate & generally somewhat misleading.

The 'FlySky' components are utilizing advanced & cutting-edge 2.4 GHz 'Automatic Frequency Hopping' technology.

This ensures virtually bomb-proof & interference-free control, of any radio-controlled models.
 
The 'FlySky' Receiver is however, VERY AFFORDABLE !



For anyone wanting to 'do something down', "cheap" is a great word to be describing things as.

I'd stick to 'affordable' myself & just describe some other systems as ... VERY EXPENSIVE !



" 2 thin wires from a battery via a switch to this tiny Rx and 2 from the Rx to the motor is a far simpler installation "



Sounds GREAT on paper Juergen !

However the 'reality', at least as far as I see it, is probably somewhat different !!



Many users will wish to use more than just 1 battery.

Many users may well wish to use an additional 'DC-DC Step-Up Regulator'.

Still further installations might want to introduce extra charging-sockets to the spaghetti-bowl.

So really, in terms of the number of "wires", to my way of thinking, having a built-in E.S.C. or not, makes little difference.



I would be the first to agree with anyone, that there is more than 1 way to skin a cat !

However this Thread is all about skinning that cat, using the easily available & affordable 'FlySky' based solution.

As such, it is really just so so so unbelievably TEDIOUS, beyond what I can express here ...

... when people come along, and hi-jack Threads which are intended to help users with info. on THEIR chosen R.C. system.

There are plenty of Threads in the R.C. Forum, where Members can give themselves a jolly good back-slapping regarding THEIR OWN choices.



Ideally when someone comes to get helpful & accurate information on installing & using the system THEY'VE chosen ...

... it's nice if they don't have to wade through tons of irrelevant & Off-Topic Posts on how some other different system works.

It would be extremely helpful for 'FlySky' users ...

... to have JUST ONE ! teeny-weeny little Thread on this Forum, for them to read about THEIR choices in.

This is the ENTIRE TEXT of my original Post ... Which is from a different Topic & was Posted on ... 9th May 2017



- - - - - - -



In looking at all the possible options for the project, one thing was paramount ...

... COST !

AND high-quality !!

It seems to me that economy AND quality, are easily achievable TOGETHER, no problem.



I might come back and describe another option I came up with also.

But I do have an R.C. receiver winging it's way to me at this very moment.



I went for a 'modular' approach, rather than an 'all on 1 board' scenario.

This will allow easy & cheap 'swop-out' of any individual failed components, in that unlikely event.



I looked at 27MHz AM/FM, 40MHZ, 35MHZ (I think ?) & a couple of others as well.

The overwhelming conclusion I came to, was that a 2.4GHz system, was by far the most economical & easily available.



It was not possible, despite a lot of looking, at both new & 2nd hand R.C. gear ...

... to buy ANY receiver, as far as I can tell, that is cheaper than this one  .  .  .



Easy to get from tons of suppliers.

No soldering required, although pins CAN of course be soldered to if needed.

Probably easy to remove the plastic case, for an even more compact board.


And of course cheap !  .  .  .  VERY CHEAP !!


£3.84p inc. P&P


It's not actually possible to get a whole pint of beer for that these days.


( they can also be bought as a Rx. & Tx. 'FlySky' twin-set, for around £20 inc. P&P )

OK then Si, my post "isn't really helpful" and then you delete another of my posts! I do not appreciate the way this or other threads are being "moderated" and I will probably not post any more here. Let's see if you delete this post.

Hi Woodie.



No your Post No.154, In my opinion, wasn't the slightest bit helpful.

What do you want me to say ? ...



" Or...get a receiver which has a "built in" ESC.
Much less BS than trying to fit several pieces of electrical bits inside the loco, etc.
I know...I know...nobody wants to hear me recommend anything but the KISS principle applies here also."



We are talking about a SIMPLE wiring problem in the Thread, by the looks of it.

I fail to see how what you Posted is any help whatsoever.



The Post you made is STILL THERE THOUGH !

So I'm not sure what Post of yours YOU THINK was deleted ...

... because there has been NO POST BY YOU REMOVED !



You need to have a good think & try and remember if you Posted anything after that.

Because what I can tell you is, simply by looking at what is here ...

... You Posted NOTHING after Post No.154.



I think you need to get your FACTS RIGHT before you blurb out what you just have.



Si.

Update:

Got a new ESC and used a freshly charged battery.

Still will not bind.

In my searchings on the internet I recall an article about how FlySky had a problem with a batch of receivers some time back.

By simple deduction it's got to be the receiver.  So, I've ordered another one to find out for sure.

Hi Michael :wave:



In all the many years that I have handled & used microchips or circuit-boards ...

... I can honestly say that I have NEVER to my knowledge, had a 'factory-fresh' item that doesn't work as it should.



However there are 2 post-factory causes of failure in my experience, that are VERY common indeed.

1. Applying REVERSED-POLARITY Voltage to such devices, which CAN result in immediate destruction of the device.

2. Static-discharge from the user themselves, when handling & installing such devices.



It seems from what you said earlier, that you HAD applied REVERSED-POLARITY Voltage to the Receiver ...

... this could have very easily, permanently damaged the circuitry instantly, as it was applied.



I have Nylon carpet & laminate-flooring here where I live, as do many other people.

I also wear a certain amount of Polyester clothing & shoes such as 'trainers'.


Scuffing around on these types of floors, wearing many modern clothes etc. ...

... can generate a HIGH-VOLTAGE STATIC-CHARGE of many many 1000s of Volts.

Not good when working with 'digital' devices that will only tolerate 5 Volts.


When handling these types of chips & boards, I will ALWAYS touch a metal-waterpipe BEFORE touching the device.

This is an easy & effective way of discharging ones own bodies built-up static-charge.

Even after that, I also ALWAYS avoid touching microchips & suchlike by their connections whenever possible.

Static discharges can also very easily come from soldering-iron tips as well.


I have not actually ever read here on this Forum, advice that's been given on handling these things safely.



As for 'alleged' faulty-batches ...

... I have actually read a lot of what I consider to be 'hype' from certain major R.C. manufacturers ...

... often speaking on THEIR OWN sponsored Web-Forums ...

... 'claiming' all sorts of so called quality-control issues, with THEIR RIVALS products !


Users feedback in these very same Forums, tends NOT TO SUPPORT these fairly suspect self-serving 'claims'.

They have an obvious vested-interest in spreading doubt about their more affordable competitors products !

Si,

It's quite possible that I screwed up.  Another receiver will tell for sure.

The first one went so well.

I'm just very frustrated that the second install seems to be causing me no end of trouble.

Hi Michael :wave:



I'm not a betting man, but ...

... I would probably bet, that it was 'reversed-polarity' Voltage, which destroyed the Receiver.



The 3-way connector from the E.S.C. Electronic Speed Controller, with the 'White-Red-Black' Left-Right sequence of wires ...

... as it comes, even if it is plugged into the Receiver the wrong way round ...

... would 'probably' not actually cause any damage to the Receivers circuits ...

...since either way round, the 'Red' + Voltage wire is always still on the center-pin.



But ...

... because that 3-way connector was RE-WIRED as a 'White-Black-Red' Left-Right sequence ...

... & the 'Red' + Voltage wire, was no longer on the correct center-pin ...

... the supplied + Voltage from the E.S.C. went the WRONG WAY, straight up the Receivers 'Ground' pin !  :shocked:



It is annoying, even more so, since your 1st install of the 'FlySky' gear, was such a great success ! :cool:


As Murphy :f: once said :-


" Sometimes $4!7 just hits the ... "






;)



Si.

Si,

Michael described that the LED's of the receiver were flashing, how could he have reversed polarity then ? ? ?


What Battery voltage do you use Michael ?
