I've some problems with the blue guide on my two Scalextric Dallara cars as it will not work together with my lap timing. I've modified a Ninco Spirit lap counter (I saw this on a Swedish web site) which uses NIR (Near IR) LEDs probably working at 850 nm. Through my work I've some

experience that some seemingly opaque plastic materials transmit in the NIR. I did an experiment to test my theory and painted the guide blades with black Humbrol paint. It worked for about 20 laps on my track (36,3 m or 119 ft) then almost all of the paint was removed. It obviously works but it's not a permanent solution.

Does anyone have any good ideas? (Except changing the LEDs, which I don't especially fancy.)

Best regards,

Claes

PS. I'm using Lap Timer 2000 by Gregory Braun. It does the job, has nice features, looks quite nice, and it's free.

Glue thin bits of plasticard to either side of the blade.

I have seen spare scalextric black guides in shops, I am not sure what the difference is between the blue and black editions (apart from the colour). They look like they would clip in fine.

Blue ones have a vertical slot in the guide post for the self centring "spring".

The blue guides are the easy fit ones, and there isn't a black version at present.

A black version is being released soon, as the same problems occur with Sport Digital.

Not sure when they will be available but it shouldn't be long.

Thanks for your suggestions!

Could I just ask what material "plasticard" is?

It's thin plastic which looks a bit like glossy cardboard.

Fit smaller tyres to the front hubs and flatten your braids as much as possible. Put lap counter on a part of the track where your cars run slowly as fast sections have some cars lifting their noses up (as does sharp braking).

Sharp braking forces the nose down.
