<{POST_SNAPBACK}>I would make sure the banking doesn't affect the lap times either for each lane, I would try to do a makeshift "prop" to test.
If it wasn't for the snow I would have gone to the "big local model shop" and got some balsa to make a prop system... May walk into the city tomorrow and buy some from "langleys" toy shop and bank one end as a test... but they are a bit pricy for balsa! and some "ferraris"
I know its going off topic but has any body seen this.....
MRE Scalextric tradeshow visit The thing that worried me the most was the "Ferrari stuation"
Quote: "There are Ferraris in the 2010 range but they cannot be marketed. Why ? Because Carrera now have an exclusive licence for all Ferrari slot cars and all of the SCALEXTRIC production must be produced and released in the first half of the year. Whatever remains at 30th June must be abandoned and destroyed"....... so probably gonna go pick up the few ferraris i do want while they are still on the shelves... the collectors are going to wet themselves!

<{POST_SNAPBACK}>You could make a removeable chainlink fence. Some mesh with poles attached then "tubes" or something on the back of the walls to locate the fence? Would add a few minutes to your set up time but you get what you want then.
I love the removable poles idea... Only problem is.... I was planning to run the wires for the LED's up the centre of the poles... If i could find a flexible enough fence i suppose i could "hinge the fence posts... put 2 small magnets on them to hold them "up" and use them to transfer the current... from a "ring main" under the track... mmm
Has anybody used these fencing products?: Slot track Fence Kit - FK-2: Straight fence kit is now available. The benefits of the straight fence kit is that fitting is easier without the need for wires at the top section of the stanchions makes these kit easier for non permanent track layouts. As with the FK 1, for fitting you can buy some of our fixing clips for use with plastic track (CFP) or wooden track (CFW). You can also purchase additional straight stanchions (SS10) in packs of 10... The fence kits (FK 2) have 10 of our new angled stanchions and a roll of mesh 1.75 metres long by 70 mm wide. They also include instructions on how to assemble it. Note the picture shows the fence its self being painted in grey. Item comes green in colour....

<{POST_SNAPBACK}>With regard to a "scale" banking. 24 degrees is 24 degrees. It would be like saying "I am building a square house with corner angles of 90 degress, at 1/4 the size, so i will have the corners at 22.5 degrees on the model"
Thought about this issue a lot today... and we must remember that when we scale things we decide what it is we are scaling...
I kind of agree with you but when you think about the "scale" issue....To get the corners to be to scale they would need to be "Radius 8" which would be Radius of 4'6" or require a board of 9ft diameter/width... this would give a corner circumference of (2 x pi x R) of 28ft or
3'6" to the 45 degree point of the curve... From the 5 degree banking on the straight this is roughly a 20 degree rise in angle over 42 inches....
or 1 degree rise in steepness for every 2 inches travelled...
So to keep my layout in line with the prototype... My Radius 2.5 Curve is 18"radius wfich gives a circumference of 9.42 feet or
1.2ft to the 45 degree point of the curve so for the banking to raise at the same rate as the prototype of
1 degree every 2 inches gives a 7 degree tilt over 1.2ft at the 45 degree point of the curve...
To to get the angle to 24 degrees in the same 1.2ft would mean tilting the track up 4 degrees for every 2 inches of forward travel (roughly 3/4 inch)... now thats way way to steep to be prototypical...
Bam i agree with what you say... but how quickly the banking should rise is more of more importance to correct handling of the cars rather than the actual degree of slope... (possibly?) The 5 degree angle was worked out from the r2's of my first design... not the R3 single lane... (but it was late and i was on pain killers... please excuse). To me 7 degrees looks like the maximum angle required
(a banking height of around 3cm) to give the increase in slope from the straights to the 45 degree point of the curve...
I apolgise to anybody if i have not explained the maths well or to anybody else if i have oversimplified or made a mistake.... or just bored anybody to death!
again anybody got an opinion on this... and a big thank you for all those that have replied already...
