I am not sure if others do this: I really like Carrera's cars as I consider them to offer incredible value for money. Even though I only run on analogue tracks in analogue mode, because the pricing is so reasonable I am quite happy to pay the few dollars extra for Carrera digital cars to get the lights. All you have to do is set the cars in analogue mode by putting the car on the track and pulling the controller trigger three times. This puts the chip in analogue mode and you can comfortably run the cars on an analogue track. Note that I run 1/32 only.
In recent times I have experienced a bit of a quirk though: when doing this, the newer cars have exceptionally heavy brakes. When you let go of the trigger, the cars STOP. They do not slow down: it is just BANG and the rear wheels lock up. I first encountered this with a Porsche 917. Now for some of you this would not be the end of the world but I tend to use very little brake when I race so this is not what I like.
The fix is very, very simple: I put the cars in analogue mode and then tap into the leads between the guide and the digital board. I run leads from there directly to the motor. In this way I get it all: digital car running analog, working lights and normal brakes: what is not to like? All this for a few minutes of work.
And just to note: the Carrera C7R is a beauty!!! The modelling, the paint finish, the tampo: gorgeous! All this plus a well running car (with just a few basic tweaks) for this low price? Fantastic!
Well done Carrera.
