For loco operation, I'd stay away from those 2-ch car guns - they just do not offer the operation comfort I need. Even for less money, you can get a decent 4ch joystick controller ( much better suited for RR operation, I assure you ). If you decide to include some functions later on, the transmitter and receiver are able to handle them. Re ESC - That braking feature is not needed, and the noise generated by a 2kHz ESC can be annoying with time, as I have found out.

Helmut,

Yes, I like that.  Like you said, probably much better than the gun type controllers.  You'll still need an ESC, right?

Forgive the dumb questions, I'm kinda slow sometimes.  Too many prescriptions.

I use Deltang boards.  The rest of this discussion is doing my head in.

Tested my rail truck with the new 20RPM motor installed.  Approximately 13 minutes to go one foot!  For all those that want sloooooow locomotives eat your heart out.

According to my calculations a scale mile in 1/35 would come out to about 150 feet.  13 minutes for 1 foot equals 1950 minutes (32.5 hours) for 150 feet, or something like one-third mile per hour.  Talk about counting the ties!  Maybe that's too slow?  Got another motor on order; this one is 200RPM.

@Michael M
The ESC always is extra with that kind of R/C equipment.

@Michael M

with the new motor it may be up to 3 mph, how are you ever going to keep it on the rails?  ;)

Hi Albert :brill: ... Erm ... I mean Michael :wave:



Sounds like you've just invented the Quantum-Drive Railtruck !  :shocked:



According to my calculations ...

... while it's doing a circuit of your layout to the ore-bin ...

... You could drive to the shops ...

... pick up some food ...

... get home & cook it ...

... enjoy a nice siesta after eating ...

... & then go back to see if the railtruck had made it yet !! ;)



L:



Si.



Can't wait to see what happens if you make a Speeder. :slow:

One word with respect to the cheap R/C systems that are mentioned in the R/C threads. When buying standard R/C equipment, you have to keep in mind that it is modular, i.e. there is a receiver module and one ore  more ( depending on channels supported ) action modules. These are furthermost an ESC, plus another servo or electronic function decoder, if desired. The receivers all have a standard size, that is in the 36x22x13mm³ (LXWXH) area ( plus or minus up to 3mm in width and length ), and because almost all have their output sockets oriented vertically, the height needed is ~22mm including the necessary plug of the ESC or whatever. This is, even in 1:35n2, some volume you have to provide. Then there's the additional footprint of an ESC, which in the most positive case is some 20x20x6mm³ plus some leeway for the cable+plug. The situation becomes worse if you want to include light control and maybe remote uncoupling.
You need another function module for that, and the ones you can get commercially have at least the dimensions of an ESC.
Now compare that to a 'dedicated' system that is also available and has frequently been mentioned in this board. There you have the motor control ( HF to avoid those nerve-killing sounds some standard ESCs emit ) plus light plus some ancillary outputs, all on one tiny board. E.g. a  1xMotor 1.3A @12V, 1xServo + 6 ON/OFF outputs measures  23x12x6mm³ and can also be controlled by a standard dirt-cheap DSM2 2.4GHz transmitter if you do not want the stock transmitter offered.
Of course, the price is higher than for the cheap standard ones, and they are OK in the larger scales where you can find the space. I only want say that if your space is at a premium, think twice before buying.

It depends on the receiver/ESC you use...AND the battery. Above is a more or less "stock" Bachmann 0-4-0t Porter with all the "stuff" in the cab and still some room for boiler backhead and engineer. The board is a LOSI B0803(under the cab roof along with the on/off switch) and battery (under the firemen's window) is a 600MAH 7.4 volt Li Poly. Operationally the loco runs like it did on DC except there is no stalling and of course the speed is PROPORTIONAL forward & reverse. This little lokie has been giving great service for over 10 years and works with her brother, an 0-4-2t at the smelter.
I just wanted to point out what an operationally acceptable "cheap r/c car board" can do.

The nest of wires were "cleaned up" and the larger wire on the cab roof is the antenna which now appears like a length of hose attached to the steam line on the dome.

The LOSI board cost less than $40 USD and the battery was about $14 USD. Yes, this is old fashioned 27MHZ AM but it works and works like "burnin' hell".
