Souped-up Scalextric Chassis - BAracer - 2nd-Jan-22

I recently bought an old Scalextric Astra V8 as the basis for a potential Auslot Touring Car Proxy entry for later this year. I instinctively sought out a couple of 3DP chassis to try out under the body as the 'standard' upgrade route, but neither of them were a straight forward fit and would require some modifications to the body. So I had a play with the original chassis and installed all the main components I would be using in the series, and at first sight, everything seemed to slot into place quite nicely...

The series has a 23k motor limit and runs on smooth wood tracks. I am thinking that the rear bushing will need upgrading and the uprights will need a bit of bracing, and I will need to drill a couple of holes in the motor bracket so I can screw and glue the motor in place. But does anyone have any experience of pushing Scalextric chassis beyond their original performance envelope and have any advice for me?

Thanks

The best thing I ever did to an SCX Ferrari 550 Maranello was carefully fit a SlotIt SW pod to the original chassis, sleeve the front axle with 1/8" brass tube, fit a Shark 22 and NSR Ultragrips and it flies and handles beautifully...and can keep up with most Moslers on our track Thumbup

I'll add front axle support to my list.

JS Chassis are designing/builing me a 3D chassis for the Thompson Astra with provision for a Slot.it sidewinder's pod. I'm not sure if this is the one you need as this is liveried as a BTCC car, but I undertand the DTM versions are similar if not the same.

You will of course need to remove the lower side skirt from the existing chassis (the white bit in your photo), and reattach to the body shell. Very easy to drill out the mounting points to remove.

My chassis should arrive any day soon so I can let you know any problems Contact John May via JS on Facebook (although he may also be on here), for more info or to order if you wish to go down this route.

I do have a couple of chassis from John for the Astra, one for an inline pod and one of their Gtech ones. But I thought I would set myself the challenge of seeing how far I could take the original chassis first.

Using adjustable front axle blocks will certainly help,.......use your new jig to align !!

As you mentioned, decent rear bushings, and a brace for the rear uprights will also help considerably.

Remove the molded in front axle retainers on your Scaley chassis and either glue, or screw in the new ones.

RE: Souped-up Scalextric Chassis - Nonfractal - 3rd-Jan-22

The ultimate chassis mod for your original scaley is the ChopJob route (inferred by Kevan above)
The chassis has to be cut using a sharp carpet knife using a jig to ensure the cut is straight, correctly sized and correctly aligned.
The chassis has to be drilled to take the motor mount screws.

ChopJobs are still the norm at some clubs where uptake and acceptance of 3d chassis technology has been slow.
It is a risky procedure. A one way trip, but if you are willing to risk a chassis on it, it is a route you might want to try.

Happy New Year Chopper Alan. I get that the motor/rear axle relationship needs to be rock solid to assist with a clean gear mesh. Obviously a pod is a sort of short cut to achieve this, but I will have a closer look at the existing chassis to see what can be achieved.

Happy New Year Chris. I will have a good hunt for some axle blocks, but my letterbox is always open for a surprise delivery! How did I ever survive without a jig???

Underlying all of this is the obvious joy of being able to turning up to an event with a 'standard' Scaley and wiping the floor of the podded opposition (this is only one of my many slotting 'run before I can walk' New Year resolutions...)...
