A properly set-up lanier Predator (TT Pro-46, 9x7 or 8) is probably as fast if not faster than my Patriot/Jett-50 but my goal is not just speed- I like the looks of a prop-jet, retracts, long 4 point rolls etc.

I guess it depends on what your preferences are- as Rudeboy and js3 mentioned a quickee and f3D composite are a huge difference in performance and speed, same with the Magnum vs Patriot, the Mag is MUCH faster-

What gear do you have or want to run?
What price range you in?
What skill-set do you have?
You want L/G?
You like deltas or traditional?

If I had a Jett-50 and a couple metal gar servos I would choose the Whiplash or Diamond Dust- or a Magnum> Period
