Not the 6000 on 4S, the Wicked 4800KV on 4S @ ~430 watts. I flown many of the 50mm series and you will find most when flown on ~400 watts will be in the 85 mph range, the the F16 on the same watts will be about 95 mph and the Screamer will be about 100 mph. (A few are slower like the F22 and F35). So the Screamer has the best speed potential.
I have seen Youtube videos with the the use of a GPS speed meter called "Voltron" I think. The speeds it reports are way off. A model that is really flying ~115-120 mph will be reported on that GPS logger as 140-150mph.
