Hi Nick, Cheers mate. Good to see your set-up too. Absolutely agree the Tamiya TT-01E is good chassis for the Quicksilver class. You've got it spot on with the ethos thing - that's why I'm loving this class. Being able to enjoy racing with any chassis, even a basically box stock cheap Tamiya chassis is great. That's why I'm so pleased how well mine has performed as it is.
I'm in no doubt my car could perform better if I didn't drive like a girl

( Oh hang on - Charlotte consistently beat me - I'm hoping to improve my driving so I drive like a girl!!

) Anyway credit to you for getting the Tamiya Merc shell into the A final - I found the one thing that that made a huge difference to my car was when I swapped from the realistic Tamiya Subaru Impreza shell it came with to a racing shell. The handling was transformed immediately. Shame as I love the looks of the Tamiya shells.
