Scalextric have stated on their website why they have introduced the new
guide:-
"A new guide blade system has been introduced to the range. The first car to have this fitted will be the TVR 400R due later this month.
Here's a 'guide' (excuse the pun) to some of the features:
1/ The blade can now turn further through the arc than the previous Scalextric guide blades.
2/ The guide plate can now be replaced without replacing the entire guide.
3/ The guide is hard-wired to the motor - no intermittent electrical contacts.
4/ The self-centering spring has been replaced with the traditional self centering effect of the guide blade wires.
5/ Cars will come with a pack of replaceable guide plates."
There is not mention of digital but there are a lot of good points listed including a bigger turn ard before it hits the stop and no intermittent electrical contacts.
AHA - no intermittent electrical contacts!!!
Interesting!!!
