Thanks for the info, that helps a metric TON. Simple power swap connectors and I can use all my parts and pieces, what a deal !!!. I'm currently limited to two posts a day, forum still thinks I'm a new user, so sorry for not getting back to you sooner. This means my posts may be a bit longer since I only get two.
I finished redoing my layout. I'm migrating from the Digital PB 6 car to the Arc Pro. My space is 12'x10' platform. It's retractable into the ceiling so I'm sorta limited on vertical changes in height on the track. I also wanted both a high speed oval as well as a road course. I figured out a solution requiring me to swap some track pieces when wanting to change between the two. Not the best but it works.
A few key aspects. On the oval course, well, pretty straight forward. Looking forward to some high speed side by side racing.
On the Road Course, I love the pit lane. It forces users to consciously have to make a lane change exiting the pit row to get back to the track, otherwise they just loop through pit lane again. I expect some excellent swearing and rage anger on that one. I also made adjustments to give a marshal room in the middle of the road course. In the past, marshals were stuck on the outside of the track and being 12'x10' made getting to interior cars when they derail a real pain. I think I solved that issue.
Of course, I welcome any feedback, especially if I did something wrong. Too bad Scalextric doesn't make a straight pass through that you can manually lock into place. Like model railroads, it's a straight piece but it has a turn built in that can redirect the train onto a turn instead of straight ahead. Then swapping between oval and road course would be a breeze, just set the two passthroughs for both entrance and exit of the road course. Ah, one can dream....
