Let me first say hello.My question is will x-tractions run ok on 15 volts.
I have a pyramid 26 and was setting up a two lane layout with about 30' of running lanes.Just wanted say this is a great site and once again hello and thanks.

They will run just fine on 15 volts, but we have found them to be more controlable at 12 volts. :thumbsup:

Like Ragnar says, 15 volts is fine, I have run them at 15 or 16 on mine and they are so much more driveable than at 18.

They also run great at 12 vdc in a stock configuration

I second that.

And I will third that...
(Higher voltage is not always better....) lol

Welcome to the Board Mac!
I agree...the taller geared pancakes are more tractable with a little less voltage.

Thanks guys, I really appreciate your time. Thats great I can use my pyramid 26, an adjust the voltage down to 12 volts.That will work for my 1/32 and ho layouts. Also thanks for the welcome.On side note, Roger I've seen your craftsmanship posted on HWR,outstanding work.Thanks again......Mark C

Wow. I'm running everything HO at 20 volts.

However, doesn't the voltage required/desired really depend on how clean the power source is? I understand that a good, clean power supply will appear to supply more power at 12 volts (because it's smooth and constant) than a "dirty" supply (like a wall wart or old Aurora pack) will generate at, say, 18 volts.

Yes the cars will run better with clean power, they will also last longer. That is why it is a good idea to get a nice clean well filtered power supply, like a Pyramid, Pyle. or MG. Also you need to get one that will supply good current, as too low of current will damage your motor's commutator.

I believe so. I'm running a Tenma variable voltage regulated 3 amp lab supply.

A 12 volt car battery works great and they can draw all the amps they will ever need.
