Speed Range is important, not just all out speed. I have a fast wing, but rarely use all the speed and instead bob along within the trim ranges. Infact the last 2 flights I didn't even move the trims, I was happy with the speed and agility I was getting a neutral trim.

The Paramania has a lot of speed range on the trims alone. I think is 70/30 Trims to bar ratio. Dudek is often 50/50. Far as I know with Ozone, it changes depending on the wing. As it changes between model I feel ozone need to make it clearer which wing is trim or bar bias, not that they give you any indication of speeds. Yes I know ppg speed is very subjective but at least gives you an idea when looking at the range. For XC i wouldn't want to be on the bar for long.

I myself am liking the sound of the V4 but what size to buy gets difficult to judge with out test flights. When I discuss with a pilot their weight, ability, including engine power etc, expectations. From that alone I can give them a good indication which wing in which size would suit them from Paramania, but thats easy as theres 3 to choose from. 

Then what about the new Ozone Freeride. Slalom Replacement.

There is room, I don't know how given the range of wings but I feel there is room for an XC Viper. Same wing, more speed range on the trimmers, less on bar.

Vince... that is why people should go to a dealer who has experience of flying these wings and whole Ozone range, and has demo models available to try...

I have  Average speeds and fuel burn for my all up weight on the Mag Max Speedster/Speedster 2 Viper 3 Viper 4 Slalom and Roadster2.   

Looking forward to flying the Freeride very soon...

Hi,

I'm Adam, PPG pilot from Poland. Today I had oportunity to fly, test and to do some measurements on Viper 4 20 (75-150kg).

This wing was significant overloaded, because my take off weight (incl. Thor 200, wing and 5l of petrol) is about 168-170kg, what gives wing load of 8.5kg/m^2.

Unfortunately this is biggest V4 size available now in Poland, and didn't have another possibility to test this wing in more appropriate size.

My everyday wing is Hadron 24 (7.1 kg/m^2), and, despite the weight, I'm footflyer.

Because totally lack of any numbers about Viper 4 on the net, I decided to put here effects of my today measuring. They may not be 100% accurate, but may be useful for reference.

Slow trims, no speed:
 - level flight speed: 46-47km/h
 - descending: 1.7-1.9 m/s (with brakes 1.5m/s or even less)
 - max climb: about 2.1 m/s

Half trims (white sewing), no speed:
 - level flight speed: 51-52km/h
 - descending: 1.8-2.0 m/s
 - max climb: about 2.1 m/s

Full trims, no speed:
 - level flight speed: 56-57km/h
 - descending: 1.9-2.2 m/s
 - max climb: about 1.8 m/s

Half trims (white sewing), full speed:
 - level flight speed: 74-75km/h
 - descending: about 4 m/s (but initially even more than 6)
 - max. climb: 0.7 m/s

Full trims, full speed:
 - level flight speed: 77-78km/h
 - descending: about 4 m/s
 - max climb: 0.7 m/s

Release the throttle, and free descending gives additional 2-3 km/h.

In this configuration T200 is a bit too weak for satisfactory usage, but still enough for thermalling or trips.

Despite the wing load take off and landing weren't as demanding as I expected (on slow trims take off speed was very similar to H24), nevertheless landings was quite fast (at least before use brakes at end of flare) and they required a lot of precision.

Oscillation (in my setup - wing load, goose neck bars) - a bit with trims, not growing, and only after trigger. Easy to handle with brakes. Much better than V3.

In my opinion this is agile, efficient, quite fast and nice wing. Very versatile, great for PPG thermalling, significantly more stable than V3, but still VERY DEMANDING in turbulent condition and for experienced pilots.

I'm thinging about buy size 22.

Best regards, Adam
