Following Daves question in another Thread, about my 'FlySky' R.C. component sizes ...

... I thought I'd put up the basic measurements of my R.C. parts, which may be of interest.



- - - - - - -



'FlySky' 2.4 GHz receiver.



The 'FlySky' receiver comes in an easily removed, screwed together plastic housing.

Removing the circuit-board is as quick as taking out the 2 small screws on the back.

Since 'naked boards' are the R.C. 'norm' for space saving ... My plastic housing is HISTORY !


I also intend to remove the fairly bulky 0.1" pitch connectors & simply solder on 'flying leads'.

With these slight mods. to the basic product, the 'naked board' dimensions are ...

... 20mm x 32mm x 6mm


Some photos of the basic P.C.B to follow.



- - - - - - -



E.S.C. electronic speed controller 10-Amps.



The E.S.C. comes with PLENTY long enough flying-leads already soldered to the board.

The 'naked board' dimensions are ...

... 23mm x 24mm x 7mm



- - - - - - -



DC-DC 'step-up regulator' 9-Volts.



I more or less have TWO different power options for my R.C. installs.


1. Use a single 3.7-Volt LiPo battery & the above ^ 9-Volt 'step-up regulator'.

2. Use a pair of 3.7-Volt LiPo batteries & no 'step-up regulator'.


I haven't chosen which yet, I will probably decide, based on the dimensions of the loco.

The 'naked board' dimensions are ...

... 15mm x 23mm x 6mm



- - - - - - -



LiPo battery 3.7-Volts, 380mAh.



I bought 2 of these batteries to check out.

Basically I got this size since the 20mm width fitted my original Plymouth hood & other voids in the loco.


It looks like my first R.C. install may well be my Porter however.

This particular size battery may well in fact suit other possible future R.C. installs for me also.


The battery dimensions are ...

... 20mm x 39mm x 8mm



- - - - - - -



It is possible to put together a high-quality 2.4 GHz frequency-hopping R.C. system affordably.

All my components were bought from eBay listings, for the following prices :-


Receiver - £3.84p inc. P&P

E.S.C. - £2.54p inc. P&P

Regulator - £0.64p inc. P&P

Battery - £1.36p inc. P&P



:!:



Si.



I had thought about starting another Thread to 'specifically' describe my Porter R.C. installation.

But have decided to keep on with this Thread, for ALL my R.C. ramblings.


I'm going to 'edit' stuff in this Thread as I go, hoping to stay very much 'On Topic' ...

... & trying to focus ONLY on my 'FlySky' related R.C. projects & components.


As you guys all know, I'm not an   " OFF TOPIC ! "   shouting kinda guy.

But I think there is sometimes a need in more 'technical' based Threads ...

... to keep to the subject, as I'm sure it helps in understanding stuff.


:)

Si,

Any information you post about RC is extremely helpful for me.

I'm currently working on another Plymouth conversion to BPRC using much smaller components than before.  It's looking very promising and I'll post a few photos once I make a little more progress.

Thanks! :2t:

Si,

I'am with you on all the parts except the regulator - what is that and what's it used for?

On the remote I would like to use the 2nd channel to blow a hooter (or LED).

I've used an old servo board (removes the PWM) to power a buzzer (works well) but it's just not a train type sound.

Any thoughts on a hooter small enough to fit in an O scale unit?
 
George

Hi George :wave:



" I am with you on all the parts except the regulator - what is that and what's it used for? "



George, I'll Post a full description of how the DC-DC 'step-up regulator' can be used later. :slow:

In brief for now though ...

They are 'mainly' used to UP the available Voltage, by people who can only fit ONE battery, in fairly small locos.



In your O-scale locos this is probably not the case & a regulator is probably not needed.

I figure you have the space to easily fit 1, 2 or 3 batteries, 3.7, 7.4 or 11.1 Volts respectively.

So I would guess you will be using either 2 or perhaps 3 batteries, depending on what top-speed you want.

In which case a 'step-up regulator' is not needed. :)

I started to collect & experiment :brill: with a number of affordable & interesting sound devices HERE :-



>> THE REPLICANT << Experimental 'Steamy & Gasoliney' Sound-System



There are numerous easy to use, small and VERY AFFORDABLE 'digital sound sample' boards available.

Operated as you have done, by something like a spare-channel & servo board ...

... connected to a nice chunky loudspeaker, I'm sure a great horn or bell sound is possible. :bg:



Any MP3 or WAV file sound from your computer can easily be loaded onto many of these boards.

Many others even have direct audio-recording inputs or built in microphones.

The Net has TONS of interesting sounds that could be used, or just record your own. :cool:



It would be interesting if you started a Thread on your install George. :thumb:

Your specific R.C. project could be discussed in more detail then.

The special requirements such as researching & implementing a good horn-sound, would be good to Post about as well.

Si.

Thks Si.

Yes I use 2S Lipo's and so far very happy.

Ok, I'll work at the sound effect soon.
