MMC in n scale vehicles an alternative to dc car ?
Hi
I am A French MRRfan actually trying to choose a control system for a future n scale FCS layout
I had some difficulties to get user's experiences about the mcc system which seemed an alternative choice to dc car system . I would greatly appreciate your advises concerning this project .
my objectives are
Control of the vehicules trafic (planning of routes and circuits as in train controller or windigipet)
Very smooth control of the speed , acceleration and braking
(my vehicules are n scale oldies truck that should not run over 40 kmH in n scale) the roads will mainly be in city villages or winding mountain landscape )
Installation of front rear lights stops and blinkers
Ability to install decoders and hardware in N SCALE FCS trucks ;
My internet searches and comparisons drove me to two possible choices dc car or mcc and the following analysis :
Advantage of DC car
-Smaller decoder (7x15x2,5mm vs 17,3x12,8x4 mcc) no coil needed no interference with vicinity motor (important for n scale vehicles )
-Seems more simple concerning digital Field hardware (loops) and software installation
More widely spread system and according advantages in terms of products availability
products technical evolutions and support ( more German and English forums)
_System supported by the leader in railroad software control (traincontroller auto control street)with thousands users
Drawbackd vs MCC
The control of Speed acceleration Braking seems better with back emf and speed control ( on the videos the DC vehicles accelerate and brake more abruptly whereas the MMC equipped vehicles seemed start very smoothly and have a slow acceleration and braking rate.
(better cv control capabilities ?…)
DC car is a light sensible device and my layout is lighted with neon lighting moreover I enjoy playing with the layout with sunlight when the weather is fine the sunlight is very pleasant and make the scenery look beautiful
DC seems to offers less control possibilities in terms of custom driving
Unfortunately I m living in southern France and cannot attend DC or MCC workshops to make up my mind with real experience .
I saw a lot of dc car installations in n scale vehicles but I found no example of installation of mcc in N scale vehicles , this make me wonder if I could succeed in a such enterprise. I'mfeeling like a newbie in an unexplored field
my calculation with decoder coil (what dimension?)and 70 to 150ma 3,6v lipo batteries+ necessary plugs make me think it is challenging but not impossible in a n scale truck ( sure in a truck with trailer ) not so evident in a bus …..
I dont know exactly the current draw of the device in case of too high current draw from motor + Decoder I thought I could also use low consumtion leds (2ma) with light conducting wires
to spare the lipo batteries . I know that I cannot expect a very long running time
the actual vehicules with a 1,2v 300ma run more than an hour I would be satisfied with a reduced range as long as the previous requirements are satisfied ( smooth acceleration: braking ,slow speed abilities , lighting possibilities
It seems that heroes in this forum (hello Martin) succeeded in some n scale vehicles installation but as I dont understand Dutch I didnt got more information …. (installation tutorials type of battery used , how long does the vehicle drives before running out of current etc)
As the time investment would be in any cas important I would very much appreciate your comments advices experiences to make the right choice according to my (too?) high requirements
I' aware that I penetrated here in a mcc dinamo chapel (the language of which seems to be only dutch...) and hope I didnt commited any blasphemy in this case I beg for mercy and believe : I remain open to a conversion..... best regards Patrick
