Try to listen to what these guys are telling you.
We’ve been racing the Kyosho Inferno GT for a while.
The car is well balanced, with a few upgrades, it makes for a competitive racer. The factory engine works fine, I’d suggest running it with 16% - 20% fuel in it.
These days I think most tracks running them in “Spec” class are allowing any of the factory options in your owners manual, at least that’s what we’re doing down in Florida. We're also cool with any body or rubber tires.
The funny thing about it all is, a lot of times a well set-up “Spec” car will beat a modified car on a race track.
I’m sure everyone of us “Spec” racers can agree with that, right guys?
