Any chance of posting a photo of your modified chassis? Regards GregAt Gaydon, I showed the Scalextric guys my Scalextric Lotus 49 chassis which I have modified so the front part is joined to the back by a semi-flexible screw-joint which I copied from the Policar classic F1 chassis.
Without a magnet but still with the standard Scalextric motor, gears and guide, it is competitive with a genuine Policar classic F1 on my short home track and it handled well on the big Policar GP track at Gaydon, too, when I sneaked a quick run for it between races.
Scalextric’s reaction? Their customers wouldn’t like the loose chassis mounts and would send the cars back to be ‘repaired’…….!
