R/C Analyser

a digital tachograph for R/C model cars

Published in issue 334, July 2004

This R/C analyser measures and stores the speed of an R/C model car directly in the car. It is aimed at R/C model car builders who want to know how fast their models can go ‘on the road’. The R/C analyser measures the speed of a model vehicle. The speed is measured directly in the R/C vehicle, rather than being computed from the number of laps and elapsed time. This means that the speed, and in particular the top speed, can be determined for individual curves and straightaways. The average lap speed is also obtained as a ‘by-product’.
