Si,

I got the same ESC as before.  I didn't see any need to fool with something that works.  Keeping it simple.

" I didn't see any need to fool with something that works "



Hi Michael :mex:



I can't argue with THAT ! ;)



I did buy a 2nd E.S.C Electronic Speed Controller a little while back, as a spare etc.

I haven't tried it out yet though.

I'm sure it is very similar to the above ^^ red-board one. :)





Again the price was incredible, at about $3.00c Bucks inc. P&P ! :shocked:

I thought it's slightly different board shape, may be useful for perhaps narrower situations.



The 'capacitor' component, sticking out where the wiring emerges ...

... is simply soldered in parallel with the power/battery connections ...

... and isn't really needed & can be cut off, if space is at an ultra-premium.





It 'claims' to handle more Amps ...

... but hey, the difference between 10 & 20 Amps in our small models ...

... ain't really a factor, other than perhaps in a total 'stall' situation.

Unlikely ... and replacing a £2.54p inc. P&P board, aint exactly gonna crash Wall Street anyway !! :cool:



:moose:



Si.

20 amps is kinda overkill isn't it?  I guess it don't hurt anything.  Even my Lionel engines only pull a couple of amps. 

I do like how the ESC is on the narrow side.  Could be handy for tight situations.

I do like the FlySky setups we've been using...simple and inexpensive.

The 20 A is only the current the ESC is able to handle.
It does not influence the actual  current. This is determined by the motor.
As this is an ESC from the usual car/boat RC range, 20 A potential current is not an unusual value for such an ESC.
Far more interesting with such 'standard' ESC is the frequency for controlling the motor.
This one seems to have 2 kHz. I would not want to have a loco with this in front of my nose.

Hi Juergen :wave:



Yes indeed.

I think most people understand that.

Which is why I said this about it ...



" ain't really a factor, other than perhaps in a total 'stall' situation "



I seriously doubt that particular E.S.C. would handle 20-Amps or even 10-Amps for 'long' anyway.

I believe those are 'peak' figures ... Judging by the physical-size of the power-chips.

Plenty of power-capacity for small to medium sized motors though.



:)

Hi Si,
ok, you mean I misunderstood Michael's objection. 
Then sorry for that, didn't want to carry owls to Athens.

Hi Juergen :wave:



I don't think Michael was 'objecting' as such.

I think it was more of an 'observation'.



The E.S.C. he's been using, is 'claimed' to have a 10-Amp capacity.

Which as he points out, is WAY more capacity, than even his big Lionel locos would need.



From my general electronics experience ...

... looking at the 'physical size' of the power-chips ...

... & seeing that there is no heat-sinking fitted ...

... my 'guess' is that both the small E.S.C.s shown ^^ on this Page ...

... would 'probably' handle 2-Amps continuous current OK.



But the 10-Amp & 20-Amp figures in the specs ...

... almost certainly refer to 'peak' current handling only.



As far as I am aware, both these E.S.C.s are the smallest that I've seen available.



Much much bigger ones are available of course, for car/boat applications.

These are characterized by much larger physical-size & visible heat-sinking ...

... such as this one :-











I'm sure you know all that already Juergen.

But I think attempting to Post with a view to explaining things to newcomers who know 'nothing' is important.



These 'technical' things are sometimes not explained very clearly ...

... usually under the assumption that the person reading is experienced ...

... when often they are not & reading a very  A ... B ... C ... type of Post ...

... can be very helpful to them, rather than just causing more confusion.

We hope so anyway.



:)



Si.



Without actually looking back through the Thread to check ...

... I believe Phil was using a much larger E.S.C. like the one ^^ above.

His loco was a large 'O'-scale one though.

George has also used a similar large E.S.C. for his 'O'-scale as well.

Possibly not needed though, unless for really big locos or 'G'-scale.

The smaller E.S.C.s on this Page may well be enough.



Suck it & see ! ... If you TOAST it !! ... You're out a massive great big $3.00c three Bucks for a new one.

In this price range that's surely right.
The smallest I have used were these:

I'm happy with the E.S.C.s I've been getting off of eBay for only about $3.75c

10 amps, even if only peak, should be fine for the small motors we use in HO and On30.





With my Lionel trains I use 3 Amp auto fuses to protect engines from having a meltdown.
 
I've blown a few fuses, but that's because I've left a screwdriver laying across the tracks. 

That's why I was thinking that a 20 Amp E.S.C. was kinda overkill.

Since I'm using battery power I'm not expecting any spikes or shorts.

Hi Michael :mex:


Well ... If it ain't broke ... Don't try & fix it ! ... as they say. ;)


Certainly YOU won't end up 'BROKE' $$$ :us:


Mine the ^^ same, cost me £2.54p inc. P&P on eBay.

That's $3.43c at todays rate of about 1:1.35 Pound/U.S.D.


Looks like you mighta been RIPPED ORRRF ! by about $0.32c !! :f:



:old dude:
