more power i need more power

Hay Rat,
I think they are using 20/22 volts. If you are not using continuous rail, the power drop is going to be a lot. I can ask somebody at BP about a source of track rail. One of the Tyco designers is a racer here and has hooked up some club tracks with continuous rail.

as important as the power, rails and power taps(as many as possible with fine strand large gauge wire) is the armature you are using with NEO and Polymer motor magnets. I have found that only custom wound low OHM armatures work with NEO magnets and very low OHM stock arms with Polymer magnets. others may have had different results. for H.O. I use 24+ volts with nearly unlimited amperage via two 12 volt automotive batteries in series, no charger needed during racing. for 1/24, I used pairs of diesel truck 12 volt batteries in parrallel with an high end Sears battery charger on them during racing. that yielded about 16 volts with very high amperage. just as important are the wire taps which should reach just beyond the finish line so that the amperage can be pulled all the way to the end of the track. I like 8 and 4 guage Monster Speaker wire with very fine strands for power taps and have close power taps at the starting line end, one about 6" behind starting line, one about 12" past starting line, another about 18" past that and then every 6' feet or so through the traps. Amperage travels through the molecules on the outside of each strand of wire. if you have one double 0 guage thick ground wire for a power tap, there are fewer paths for the amperage to travel on on the very outside of the very thick mass of copper. if you use fine strand wire, such as welding leads, then there are more paths for the amperage to travel. voltage is nice, but high end electric motors in any scale devour amperage.
so, make sure your armatures are up to snuff, your power taps are sufficient and your power supply is capable. if your power supply can only muster a couple amps, that motor is starved of what it needs most and I don't think that printers require much amperage. look at the power supplies for sale on eBay. do a search for variable voltage power supply. look at the prices of the ones rated at up to 18 volts with 3 amps. look at the prices for the ones rated at any voltage but capable of 5 or more amps. this will tell a story that I can only illustrate here. you might be able to use two automotive batteries in series and recharge them when not in use for less money. some people are afraid of batteries for various reason. but properly maintained, fused(circuit breakered) and wired they can provide many years of unlimited amperage and voltage for much less than many power supplies. OK, long winded enough?
that is all today about electric. maybe another day we can discuss magnet dynamics. LOL.

Thank you for the info guys

Not sure Ron, You'll have to research to see what bike batteries put out for amps. Power Supply might be the way to go, just tap into your neighbors power.
