@patez: I think rear traction isn't the flavour of the month, but the priority has gone to increasing steering (even on RM cars). The chassis should prove stiffer at the back compared to the plastic T-plate of the original tub, so that in combination with a battery that's further forward should make quite a difference... So does it actually have more steering (aside from feeling more nose heavy)?
Has anyone driven the XM yet? And even better perhaps, has anyone been able to compare it with a Vega chassis? I'm curious to see how they compare because I've been hoping for Tamiya to do something with a mid-motor layout - I'd say a plate chassis like Tamiya's might be more flexible and easier to adjust to lower bite surfaces... but of course those things are best felt by someone on the track! |
I agree that Red's car is gorgeous and the XR should have been produced in that way. The XR set up with the HRC shim under the trans and rear mount make the car very edgy. Once it's removed and the front shim replaced with a plastic 1mm shim the car is more stable. The XR has a ton more steering from front grip. The length in the chassis (and the added weight of it) make this happen. Adding the 30g weighted bulkhead adds to this even more. The rear is looser than the plastic chassis which is due to the lack of flex (no T-plate) and the length/ front weight.
