Thanks Nick. I am delighted with the result. I have now perfomed a bit of surgery on it, which I hoped would make it more competetive. The aims were to lower the centre of gravity, improve the handling, and lower the gear ratio to improve acceleration and braking.
Using nothing more than a sharp Stanley knife, I removed the magnet mounting area, and a bit more, from the chassis (I never run with manets). I then extended the motor mounting holes downwards, again using the Stanley knife. The method here is not to cut, but to shave bits of plastic away using a scraping motion. I kept doing this a little at a time, checking regularly by inserting the motor, until the underside of the motor sat flush with the chassis, then a Slot-it 9 tooth sidewinder pinion was fitted and the motor was glued in using Araldite Rapid. Finally, I fitted a Ninco Prorace sprung guide, which, being darker in colour than the standard Ninco sprung guide, has no problem recording laps and making lane changes on SSD tracks (Scalextric recommend black guides only). Here are a couple of pictures of the result:
Initial tests on my Scalextric Digital layout showed a huge performance boost over the standard car. The previous fastest lap for a March 83G was 9.2 seconds, but the modified car recorded an astonishing 8.5 seconds, equalling the times set by my Ortmann-shod Slot-it Porsches!
I can't wait to try it at Manor Farm!
