Alex-

I too have kids and experienced the same problem you had using the ARC Pro with the standard two 15V 4A power supplies.  Between races and when the ARC Pro was off, the cars were just way too fast. 

I went ahead and ordered two 12V 4A laptop power supplies with 6.3mm x 3mm tips (the ends of the stock ARC Pro power supplies are also the same stock ends for Toshiba laptop chargers..apparently).  

Anyway, mission accomplished!  

It was just enough of a power drop to help the less experienced racers run magnet-free cars like the rest of us. 

The power supplies were less than $10 each.  Just be careful when shopping for them. Most 12V supplies are going to be only 1-2A.  I wanted to keep the amps at a minimum of 4 based on comments from other forums.

Finally, there are a number of laptop adapter tips to convert a laptop supply to 6.3mm x 3mm.  I ended up using tip connectors on the two units I bought.  The standard Toshiba power supplies were mostly 19V....just the opposite of what I was trying to do.   

Good luck!

I read the forum notes from 2017 suggesting that power taps and curved lane changers were causing problems with the ARC Pro.  The same thread continued about solving problems with the curved lane changers (I do not have any) so I am not sure if the original problem was with power taps or if it was isolated to the curved lane changers?  I saw the modifications for the curved changers, but I didn't see any comments suggesting that power taps were okay?

I was planning to install my power taps this weekend (tomorrow or Sunday).  I had the regular Scalextric Booster cables on my old 7402 layout and they seemed to help.  I changed my layout when I bought the ARC Pro, so I need to re-drill my table.  

I run 4 lane digital (except when we compress to 2 lanes over the start finish line) on a 7' x 14' table.  I intend to connect 8 female spade connectors to another area of my track, similar to what I did on my 7402 digital layout.

Am I going about this the correct way or is there something different about the ARC Pro power that I need to consider?

Thanks.

It has been about 9 months since the last comment on this thread, but is there an update on the original 4 lane digital question?  I too would like to run a full 4-lane ARC Pro Digital layout.  Right now, we are 98% 4 lane, but use the pit lane pieces to expand and then restrict our layout from 4 lanes back to 2 lanes so that ARC Pro can pickup the info from the cars on the Start-finish line for lap timing and counting.

I am open to any and all options if I can continue using the ARC Pro for my race management. I would simply like a full, 4-lane layout.  

Thanks.

Chris
