I saw the DTX firehammer from FD run at the WRAM show. IIRC, it had a 3080 running on 5s. I was cool, not that much power though, it would have been better with 10s. I'd say that my revo with a 1515 1y on 4s was faster accelerating and in top speed than the firehammer on 5s, it was hard to tell though, it ran on slippery floors.
