Scalextric Cortina

[Burglar]

Anyone here set up a Scalextric Cortina for a wood (non-magnabraid) track?

I've made some mods to mine, it was semi-successful last time I tried it but the guide height was incorrect (too high). I haven't had the chance to test it again since.

Mods:

1. Lightened interior slightly using a sanding drum. Removed some of the thickness from the interior shell and removed the 'legs' that lock the body on to the chassis so that it can float more if necessary. I also had to cut the interior slightly around the front when I soldered on new wires to the motor and ditched the two bare wires leading to the standard harness, because the interior is a VERY tight fit around the motor.

2. Removed lights and wiring harness as well as the socket on the 'digital door' in the chassis. Replaced it with regular silicone wires, I think from Professor Motor. This gave me a flat surface on which to mount a 10g lead wheel weight.

3. The 'diff hump' under the gear ground off the chassis for more track clearance.

The car was tested against an unmodified version of the same model. The car ran much better than the unmodified Cortina, especially in the corners (the car without lead rolled over). The guide being too high in the chassis caused the car to deslot as it accelerated out of corners. I haven't been able to test it since I added the B-Nova adapter but that should fix it.

I also want to get some tyres for it from Paul Gage.

EDIT: here are some photographs (note that is a 1/24 scale SCC set-up block, not 1/32):

Being a small car guy I like those Cortina's, but have yet to fool with one. As with anything there is always room for improvement. Great looking cars fellas. :)

I don't have the Cortina but I do have an Escort which is roughly similar. That slimline motor that comes with it has way too much beans for a small car like that. I think the first thing I would do is to trade the motor out for one of Mark Thomas' MT motors. Something lower than 18K. I would recommend his M/t SL1 (14,702 RPM). http://www.derbycityspeedway.com/mtracingresins.html

Since you are running no mag and Scalextric cars have splined axles, there is a lot of axle/ bushing slop in the rear axle. This will cause wheel hop. The lower powered motor will help that but you might want to try the super glue trick to tighten up the axle fit.

Burglar, MJK finally do a replacement tyre for the SCX Mk II Escort. Makes the world of difference to its handling.

Nice work and a good looking car!

I prefer PG tyres on my painted plastic too, mostly, but I seem to recall Burglar thought the PGs too grippy on some of his cars. Actually, best I've got on my track are untreated 2 year old Racer Rubber. These are followed closely by Fabio series Mitchell'ns, which are hard to come by these days. Then PGs.

I didn't find the PGs too grippy. They were just a loose fit on the Monogram wheels. The same tyres fit okay on the SCC 15x7s
