Out of the box the car is excellent, some drivers have had issues with idler gears but Yokomo now make an aliminium option so nothing to worry about.

Plenty of good set ups for both carpet and astro.
Most prople seem to be using saddles but shorty lipos give you the weight option.
There is a new aliminium chassis which in theory will be better on high grip tracks but everyone is still waiting on feedback as this is brand new and mostly untested, saying that the kit plastic chassis is excellent.
The Cream front weight is popular.
