The prototype has been tested in flight to a top speed of 240 mph IAS @ 9500 feet
that over 270mph TAS, so i am very comfortable with a 210mph Vne for the lightning.
Production models, other than N430GH, have shown to be more than 10mph
faster than the prototype in a given configuration . the other 2 lightnings
that are flying are in West VA and here. Both are in test phase now and lack wheel
pants and gear fairings,optimal prop settings,ect.... however when flown
at a given power setting ...say 2850 rpm each aircraft so far shows to faster
than the prototype...due to cleaner airframe ,finish, better parts fit and a "straighter"
much lighter aircraft. All things gained and improved upon in a production
model.

Max,
The flight testing of VNE is set by flying at least 10% over that
published number. I believe that it was tested to more like 20% over for
extra margin of safety. The prototype is equipped with the ballistic
parachute and Nick wore a personal parachute on top of that. Right now the
Vne is set at 208mph I believe it is on the Lightning. The prototype has
come close to that in 100% throttle in level flight. Production models are
a little slower than the prototype. Brian W.
