Fast
42
The HPI E-Firestorm does about 20 mph. The HPI E-Firestorm Flux does 44 mph. The Nitro firestorm rtr does 48mph
20-35 mph
it does about 50mph
I have the official hpi catalogue and it doesn't say how fast it goes but from my experience I expect it will go about 25 to 30mph maybe a bit faster. Hope that helps!
