Hi Eotz,
I've not raced my DF-03 since I fitted the carbon chassis (and I'm working late shift this week so I can't go this week!
) but I had a quick rip round the car park the other day and it does seem to make a slight difference to the handling. It makes the car a bit lighter as well. I've made up an under tray for mine which protects the electrics from getting any water in them, I could do with getting some better ones vacformed up
The only problem I had with the carbon chassis (apart from having to take a hacksaw to it because my Trakpower battery didn't fit!
) is that the way they've retained the battery door restricts the space you have for fitting the speed controller and receiver. I had trouble finding somewhere for a mini Spektrum receiver and a Quantum speed controller!
Apart from that it's a very nice bit of kit. I'd recommend taking the screws out and threadlocking them, as the chassis is assembled from the factory.
