A second hand model my local dealer kept specially for me... At first I had some difficulties with central differential, which sometimes 'disengaged' rear wheels, but It’ s OK now (with a thin washer between SA11 and H3 parts). D1 part has been cut off to make motor removal easier. HPI wheels. Sport Tuned motor and electronic speed controller, as usual. Of course, driver figure has LEDs as eyes. Home-made front bumper extensions, and aluminium rear bumper. Velcro-fixed wing, on another aluminium part I made to replace E2. Wheels are now driven by a classical pin system, like all my other cars. That’s more simple (for maintenance, compatibility of wheels, etc). So I drilled radial 1,5 diameter holes in rear wheel axles & front wheel shafts. Just do it : you’ ll see they’ re made of very, very good steel!
