Thanks everyone for the very kind comments.
I'll post some more detailed pictures of the various parts of the project, the steering in particular is one of the more unusual setups, designed to fit a bellcrank system into a chassis where space is a premium.
I've also got a V2 chassis drawn up to give the front arms more "kick-up". It would have been cut from carbon fiber today too if not for a loose nut on my mill... messed up my tolerances and wasted good portion of costly CF plate. Oh well... there are days one should just know when to take a break.
Will try to get some videos taken at the next run...
BRCA legal? As I'm not from your neck of the woods I'm not so sure about BRCA rules - but as far as dimensions go I designed the car to be very very close to the RB5.
