certainly the upper deck isnt effecting the grip . over the amount of hardware and to aluminum.. please...
John, I'm with every one else here...
you look at where material has been removed and how the deck mounts, and you'll easily see that it is designed to flex more
. It's a subtle change, but still noticeable..
What also needs to be considered is its not simply just adding flex, but how
the car flexs. Look again closely at the 416, and you'll see all the chassis and top deck screws are mirrored about the centre line, and then there is the split rear bulkhead... if flex wasnt the issue, why did tamiya make the effort on this front, and why not have one piece rear bulkheads?
And you are quite wrong about the stiffness of the chassis too, could you flex a real car just by twisiting it? I doubt it! A carbon chassis plate is stiff in two directions only, longitudinal and transverse, not in torsion (they are made up of 0 / 90 UD fibres)... don't believe me, try it for yourself.
And as a final point... bear in mind how we control the cars.. by their very nature it's a remote... not by seat of the pants feel from inside. Making the car more forgiving is very much required.
I hate to say it, but your really comparing apples with oranges by comparing a real car with a 1:10th tourer. And it also seems you have made up your own mind on it. All I can suggest is try it your own way (stiff chassis, soft suspension) then try it the way pretty much everyone else is doing it... and let us know which worked better...
