The 70-80s F1 cars are not DPR - they are just too small and detailed to do it without creating odd lumps and bumps in the model - even with the F1 C8516 plug. Some of the F1 cars are fiddly to convert with the C7005 retro fit chip, but none are impossible. And there are newer, smaller chips arriving - the Slot.it Type C is SSD compatible and both Scorpius and Dr_C have posted plans in our SlotRacer Digital Racing section here. 

To be honest, it’s one of the delights of ARC Pro - I run the delicate, difficult-to-chip stuff in analogue mode.
