Ah the memories, just read the whole thread. I started with a Grasshopper, then progressed to a Fox. Upgraded with a Demon king motor, better shocks, anti roll bars, better tyres and more. Used to race at Sighthill in Edinburgh. Sold the car to a mate when I got into motorbikes. His dad ran over it when reversing out the driveway. Fast forward more years than I care to mention and I bought a Celia GT4. I’ve still got that in the loft along with a mardave mini. I might dig them out next summer after reading this. Brushless motors and better batteries sound interesting .
