I got to fly two vipers this past weekend. One with P-160 and the other with P-200 power.
P-200 has the edge for sheer vertical power, but as I showed the 160 powered viper could easily go out of site vertical after a straight run ( Not sure how much more vertical than out of sight anyone could want )
The rest of the flight envelope the P-160 buried the P-200.
Lighter
Easier to manage the speed
Much improved slow speed handling. I could really feel the extra weight of the 200 version wanting to bite me in the same low and slow pattern that the 160 version had no trouble with.
More floaty touchdown
Much softer and less aggressive stall. Both version dropped a wing but with the 160 version I could fly out of it ( Catch the wing drop ) 200 version actually went into 1/2 a rotational spin.
Oh and of course the flight times were longer on the 160 version.
The P200 Viper was still a great plane to fly ( So dont get too despondent all you guys that have gone down that route) Its just the lighter version is that much greater.
Ask me if I would ever have a P200 in one of my vipers......... Nope!

P.S I forgot to mention... We were flying at an elevated field in 30 deg temps with high humidity and the Jet Cat 160 Sx didnt struggle to fly the Viper in anyway!
