I am really having good fun getting to the bottom of the good and bad sides of Sport World.
We have been able to fix slot 2 problems, I actually think slot 2 is a coincidence as there is no difference in the control circuits between slot 1 and 2. The prime suspect is the MOSFETS controlling the outputs but these are cheap and available. There is dual package zener diode that sits with the MOSFETS and that is unobtainable since 2007 but we will figure out an equivalent work around on those shortly. So we have one control box out of commission but fully expect that to be running within the week.
What I am finding very interesting is getting the Pacer working nicely, certainly to get the Pacer running well (Fast) the cars need to have been prepared well with good braids and very clean good grip tyres, the track also needs to be clean, I use a painters tack rag on the track as this picks up the dust but does not remove the 'rubbering in' of the track.
Currently my feeling is that the Pacer can run between 2.5 to 5% of the very best lap that a reasonably good driver can do, but the Pacer will do it lap in and lap out. The Pacer really likes cars like the Porsche 911 GT3 analogues, it is pretty OK on GT40 type cars, the real test will be 1960's Formula Junior cars !!
The Sport World Pacer is anything but a rubber band around the controller, in the Youtube video you can hear both cars spooling up and down, the Pacer syncs going across the start finish line, if it de slots it runs at about half power until the start finish line until it can re sync. There is some kind of learning process taking place the first time a profile is used in a session as it slows down near the start finish line for a few laps and then picks up speed to the that set by the data lap, there also seems to be a slowing down if it is not under pressure by maybe 0.25 second per lap on 3.75 second laps.
I hope this is of some interest.
