The main chassis plate of the 'R' is from what we can tell identical to the 410 - a slightly less vibrant colour we'd put down to manufacturing variances. Where the 410R differs over the 410 is with its use of plastic composite moulded side 'pods' instead of the hugely expensive and intricately machined alloy side pods on the 410.
The new side pods aren't quite as stiff as the alloy pods as you'd imagine but have a high glass content and when bolted down to the chassis plate do give a nice strong base for the car.
The side pods have some extra support and ribbing moulded in to reflect the change in materials and a neat little transponder mould tab is included on the right hand side pod for easy mounting options that were distinctly lacking on the 410.
The chassis plate is hard-anodised and fully countersunk
Steel post on the new 410R is a nice move.
The front of the chassis is braced using steel posts that tie the lower chassis to the front upper brace and bulkhead. The posts on the original 410 were anodised alloy and whilst they looked good and were light they were also prone to bending in a heavy impact. The 410R comes with new steel posts which should handle any abuse you can throw at them and resist any 'tweaking'.
The motor mount / centre bulkhead is assembled from two main parts which later will support the slipper assembly. The side of the bulkhead that the motor attaches to is of course still alloy and whilst it essentially looks the same as that used on the DEX410 - the one here on the 'R' version just isn't quite as nicely/intricately machined, but only a keen eye would tell.
The other half of the mount is moulded plastic and has an integrated 'post' for the battery strap to attach - three holes mean you can clamp various lipo heights securely.

With the side pods in place it's time to start adding the front and rear bulkheads - a home for the gear boxes to sit. These look to be the same as the 410 and are seperated into left and right halves both front and rear. On the more expensive and more complete 410 original, the front and rear suspension arms pivoted on pins that sat inside steel balls - which themselves sat inside alloy suspension mounts all round. the 410R of course does away with all these expensive alloy parts in favour of more moulded action. A slight surprise but one that makes total sense is the move away from the steel balls - so on the 'R' the hinge pins will simply push directly into the plastic suspension blocks. This should give good material support and strength due to the thicker ring of plastic around the pins - and they do feel like well designed items that should stand up to some abuse - but time will tell.
