Several folks have commented on various threads here about 'Streets vehicles they have, that they seem to go slow. I had three or four e-mails with questions about what I mean as the "slow" speed I'm looking for. Slow is something that is subject to interpretation
This is what I mean by slow. A scale 7 mph, from 6.0 VDC to the track with 4.2 on the downside of the rectifiers to the motor and supercapacitor pack. This is the final test version of my homemade supercapacitor "electronic flywheel" earlier this morning, before I start knocking them out to put inside my cars. Without the supercap pack this test chassis will not make it even halfway around the track before it stutters and stalls due to momentary lack of contact. To run this smoothly on this track without the "flywheel" this chassis needs a much higher voltage and high speed to provide it with much more momentum - for a speed of about 35-40 mph. and no, I'm not going to run my cars this slow, but I am going to run cabs and traffic through my downtown at a scale 20 mph or so: this tests just verifies I've got vehciles with a good margin beyond what I need.
The video below shows it running slower still - only 3.4 mph but no longer smooth. In the video you can barely see it, but this vehicle is right on the edge of stuttering. Mostly I hear rather than see: I can hear lack of constantcy in the motor/roller noise - as its about to stall I can hear small hiccups in that sound.
