Well, had my first run with a 12th tonight, have to say it was really really good. These babys fly! (admitadly was using a 12x2 ).

However... there were a few interesting points.

1) I need a new rear axle, seems like the one i have on the car is split... so for the first few runs, after a slight knock the diff would go loose.... please I have ceramic balls in there now, at least they don't overheat!
2) My D4 is knackered... next time I'll put my Orion V2 12x3 in... should be better
3) Found the car very easy to tune... even with the tweak springs. easy to do with my tweak station.
Started out with a the kit standard soft rear spring and 30wt oil, with white side springs and hard damper oil. Car was way to pushy... understeered everywhere.
Followed a guide from the CRC site, and went to red side springs, and copper centre spring. Was so much better, car steered wherever I wanted. Quite impresse I got it to handle well, despite having no previous experience of the car... can only get better from here.

Next time I'll be using it will be in two weeks, fingers crossed it'll be more reliable (ended up not actually finishing any rounds). Good times.

Later
