Paul,
At this point all I can say is I know what 200 mph looks like. Right before I flew mine I watched my friend Syd fly his Whiplash which has on separate occasions been clocked at over 200 by radar and GPS. If mine wasn't going as fast as his it was pretty darn close.
The big difference is thrust and noise. While I didn't try a hand-launch for the first flight it pulled so hard with the 60L and 10X8 I don't doubt for a minute I could just hold it out in front of me and let it go like my Diamond Dust. I am also using a quiet pipe which, in concert with the 10X8 makes for a much more neighbor friendly and in my opinion, pleasant sound.
Check out that 13 oz 60 and 20" pipe!
I hope to get some radar runs on it next week along with the definite test of hand launch capability.
