I have already tried to fit proper car bodies onto RFX chassis with unsatisfactory results (Toy or
Hobby). So I decided to try a scratch build based on the RFX electronics as part 1 of my quest to
replace slot car technology with this great idea!
Above left is the dismantled RFX car parts and right is a 1/32 slot chasis, wheel and motor kit from Pendle Slot Racing, where I also source body kits.
Next step is to cut off the bits of the new chassis I didn't need – side flanges and front axle section. Then I glued on two AAA battery holders as side pods – these will take 3.7v 10440 Li-ions from china. Then I cut a 0.5mm carbon fibre sheet to form the bottom front wishbone and glue it in place.
Next, I shape two upper wishbones in carbon fibre and attach the RFX stub axles. The steering arm is a bent piece of piano wire to connect to the RFX servo mounted behind it – so the polarity had to be reversed! Next the sensors and processor board ar wired in and attached with glue (!). Then I fitted a Slot-it GT40 body – the wheelbase had been designed to fit this bit. Then paint and decals and ready to go – (newbie on airbrush!). Believe it or not it all still works in AI mode!
I'd like to see the electronics sold separately for scratch builders but as that's pretty unlikely my next project is to replicate the electronics using the open source Arduino platform and easily available sensors and circuits. First step will be simple track following with manual steering input …. no frills. I'll publish if it works!
