Hey Hitech, Ghosth and I were playing with the RV8 in the TA the other day. I nursed it up to 17,000 feet and split-s'd into a dive...
Saw 487 mph before having to pull out. The thing must be built from unobtainium..... Film is available...
(EDIT) Here's the
RV8 film. You will see 486 mph on the film, but I saw 487 on E6B, not that it really matters.
My regards,
Widewing
