Good setup for indoor on carpet

[simonrhart]

I have a good setup that suits my driving style for high-grip astro here: http://www.petitrc.com/setup/losi/se..._Ipwish201409/ but I was wondering if anyone has any pointers for running on carpet for the 22-4?

I know most people run Mini-pins on carpet but isn't carpet much similar to astro? or is it less bite?

Cheers
Simon
