Compared to some of the other members of this list, I have very little experience; I started flying five years ago and have about 350 hours on my Kitfox. >From what I understand, I can fly a little bit faster than 100 MPH, my Vne, without much risk. But when it gets a bit turbulent - and in the summer, it's more the rule than the exception - the needle moves fast in all directions. The 'book' says that in turbulent conditions, one should fly under Va, the manoeuvre speed. For me that's 70 MPH. So, when it gets choppy, I pull the throttle. Now, what is 'turbulent?' I certainly don't feel like a daredevil; rather a sissy. Better safe than sorry. So, I fly at an average cruise speed of about 85 MPH. Cheers, Michel Verheughe Norway Kitfox 3 - Jabiru 2200

Time to kick the hornets nest. Theoretically, and yes, I mean theoretically, flying around at Vne is a VERY dangerous thing to do. It means you have 0 (zero) available gust factor and quite literally any wind shear, gust, whatever, will rip your wings off. Vno, which for my IV is 99mph, (Vne = 120mph,) is the top of the green arc, where you can fly around in most turbulence without much worry. Vno accommodates a 3-sigma gust, (99.7% unlikely,) without damage to the airframe. As you increase speed from Vno to Vne you whittle at the available gust factor until at Vne it reaches zero. Now is this true for Kitfoxes? It seems hardly likely since nearly everyone I know cruises their IV at well over 100mph, and there are some that cruise over Vne. (I think I was told the world record cruise for a IV was 132mph, though that might have been top speed.) Certainly no one has ever shed a wing or even experienced flutter, so it appears that our Vne is highly conjectural. If that's the case then who knows what Vno really is, or Va for that matter since it can be assumed that the structure can stand a lot more than 3.8g's. However rest assured that when you fly around at or above Vne, YOU ARE A TEST PILOT. (Michel, I admire your courage.)
