The spur gear is a proper 48dp - 96T. The car also includes a 17t pinion.
The internal ratio is 2.25:1
Finished building the shocks last night - they are damn smooth!
An update from my previous post about the shock caps - Having used AE shocks in the past I know how much better they felt once you put yokomo caps on them so you could use the bleed screw.
So I thought I'd have a look at the Tamiya caps and see what's required to use the bleed screw. Inside the centre of the cap is a small indentation - I simply drilled though this with a hand drill (2mm bit) and discovered that after only a few twists it pushed through to the end of the existing bleed screw hole
Now it was possible to use the bleed screw correctly - as seen on the prototype cars, and it made the shock feel really nice - I'm not sure why Tamiya didn't pre drill the hole as standard
As for the design, all I can say is that like touring cars, there is a basic layout that is proving most effective overall since the time of the XX4 - that is saddle packs right at the back, and motor towards the front.
What manufacturers like Yokomo, JConcepts, Tamiya etc have done is refine the basic layout, and re-route the drivetrain for better efficiency than the XX4.
Tamiya might have copied the "concept" from Yokomo/J Concepts, but once you build this car you'll notice all the little details which make all the difference
