Dear Friends I am having trouble getting hold of SCALEXTRIC C7005 F1 Retro-Fit Digital Chip for single seater cars. Those that are out there have massively inflated prices, I saw one on Ebay for £80. Can I adapt a DPR sinlge seater chip to fit an F1 car? Has anyone out there tried it? Once I cut all the plastic away and add new wires, will it fit? Thank you for your help. POPO
