For those who remember the Arte Johnson character in Rowan and Martins "Laugh In"...."Vedddddy interesting"
Several chassis with longitudinal pivots, a couple of Penelope Pitlane examples, one that appears to be a modified stock clamshell and, per earlier posts, Policar based entrants (I can't identify them from the photos)
Given all of the other factors involved, weight, motor/gearing, tires etc. it will be interesting (and possibly instructive) to see if, at the end of the series, any consensus on chassis design emerges.
EM, cars #5, #6 and #14 all have the Scalextric clamshell body/chassis with upgraded running gear and varying amounts of ballast attached inside and outside.
BTW...unfortunately, I could not see how to shrink the #36 chassis without having to also carve at the bodyshell. The rear shocks were against the shell and the lower front suspension arms were laced through slots in the body.
On the photos posted above, I find the underside shots the most interesting. The variety of design, technique and technology on display is very inspiring. Which will ultimately come out on top will depend on many factors not evident in a photo, of course. But a careful study of the pictures combined with the Tech Inspection Details may provide some insight into the race results across the series.
Not to worry - thanks for looking at it. I see your point. I had to look at the photo to see the problem. Ah well, a nickel here, a nickel there - I'm more interested in how the various factors impact performance than I am in race position.
