M4-O8-Peak2-Venus3-GtoM&S-AD-Pure-Mantra S/M -Venus2

Launching:
1- Omega 8 25@94 = Poison 3 S @ 94 =Mantra 4 ML /MS (Very easy even in no wind)
2- GTO M & GTO Small
3- AD-Pure -Venus 2 M& S
4- Peak 2


A- Climb with a head wind (>15 km/h)
1- Mantra 4 ML @ 103 – AD-PURE M/S @ 93
2- Mantra M/S @ 93 - GTO M @ 103,
3- PEAK 2 24 @ 60 % of the load range
4- Omega 8 25 =POISON 3 S @ 95 = VENUS 3 M @ 104
5-. Venus 2 M @ 103


B- Climb > 2m/s without head wind
1-Mantra 4 ML @ 100
2- AD-PURE M/S @ 93 = Mantra 4 M/S @ 93
3- GTO M @103
4- PEAK 2 24 & POISON 3 S
5-Venus 2 M =Omega 8 25
6- Venus 3 M

C- Climb in weak thermals (< 0.3m/s)
1-Mantra 4 ML @ 98 (lightly loaded)
2- GTO M @ 103 = Peak 2 24 @ 90 lightly loaded = Venus 2 M @104 (loaded) =
3- POISON 3 S (close difference)
4- Mantra 4 ML @ 103 (loaded) ! = Mantra 4 M/S @ 93 (loaded) AD-Pure M/S @ 93
5- Venus 3 M @ 103
6- Omega 8 25 @ 94




Glide at trim:
1- Mantra 4 ML @ 100
2- AD-Pure M/S @ 93
3- Mantra 4 M/S @ 93
4- GTO M
5- Peak 2 (very close to GTO M)
6- Poison 3 S @ 94 =Omega 8 25 @ 94
7- Venus 3 M @ 103


Glide at first bar:
1-Mantra 4 ML @100 = AD-Pure M/S @ 93
2-Mantra 4 M/S @ 93
3- GTO M @103
4-Peak 2 24 @102
5-Poison 3 S @ 94=Omega 8 25 @ 94 (very close)
6-Venus 3 M @ 103


Handling in still air:
1-Omega 8 25 (A delight!)
2-Poison 3 S (A bit slow but linear)
3-Peak 2 24 (crispy and linear)=Venus 3 M
4-Mantra 4 MS @ 93
5-Mantra 4 ML @ 100 (Turns with a little delay)
6-AD-Pure M/S @ 93 (precise)
7- GTO M @ 103 (Turns with a little more delay)

They could be very close with a big difference between the O8 and the GTO M.

Handling and maneuverability in average conditions "with thermals":

1- Omega 8 25 @ 94 =Mantra 4 ML@ 100=Mantra 4 M/S @ 93
2-AD-Pure M/S @ 93
3-Mantra R-10.3 S @ 98
4-EVO-X 24/ Peak 2 24/Poison 3/ Venus 3 M
5-GTO M



Now the most important is the “handling in rough air”, and I mean is that some gliders when encountering multiple cores and punchy turbulent thermals, will react to their own, because their inside pressure is more stronger than the controls and the brake inputs the pilot are inducing. The pilot below will be a passenger for a while till the glider settles in. The more time it will take, the worse sensations you will passively feel. And that’s not good.

Some in those same conditions will be more reactive to the brake inputs, the pilot underneath is inducing and could place them wherever he wants despite the rough conditions. And that’s good efficient handling.
It is always much better being the pilot underneath a wing rather being a passenger even though for a short period.

Handling in rough air:
1-Omega 8 25 @ 94
2-Poison 3 S @ 94= AD-Pure M/S @ 95
3-Peak 2 24 @ 98 =Mantra 4 ML @100 =Venus 3 M= Mantra M/S @ 95
4-GTO M @ 103
5-GTO S @ 94


Comfort: (movements under the glider in turbulent conditions)

1- Poison 3 @ 96 (Unbelievable for an EN-D !! )
2- AD-Pure M/S @ 93 (very close to Poison 3)
3-Mantra M/S @ 93= mantra 4 ML @ 103
4- Peak 2-24 9/10 (very dampened, very close)
5- GTO M & Omega 8 25 @ 94 8.8/10
6- Venus 2 M 8.5 /10
7- Venus 2 Small 8/10
8-Venus 3 M
9- GTO Small 4/10

Easiness in flight: (In average conditions, where the pilot would be able to understand better the glider movements)

1-Poison 3= Mantra 4 ML= Mantra 4 M/S @ 95
2- Peak 2 24=AD-Pure M/S @ 95
3-GTO M
4-Omega 8 25
5-EVO-X 24
6-Venus 3 M
7-Mantra R-10.3

Stable ears in turbulent conditions !

1-Omega 8 25 = Skywalk Poison 3 =Mantra 4 ML =Mantra 4 M/S @ 95 (Stable)
2- EVO-X 24 (Stable)=Venus 3 M Stable
3-GTO M (a little unstable)
4-Peak 2 24 (Not stable)
5-AD-Pure @ 95 (Not stable)
6- Mantra R-10.3 (Not stable)


Landing and maneuver approaches to top land.

1-Poison 3=Mantra 4 ML= AD-Pure M/S @ 93
2-Omega 8 25 = Venus 2 M & S=Mantra 4 M/S 2 93
3-Peak 2= Venus 3 M
4- GTO M
5- GTO S


Conclusion:
Inserting the AD PURE M/S and the OZONE M4 M/S hasn’t been easy. Every day flying and exchanging those glider in the same conditions, was the only way to feel the difference. Then came the performance flights. My friend Moni flew an ADVANCE lightness with the PURE to be able to fly at 93 all up, and I flew the M4 with the impress 2 harness at 93 all up. This way with the same sizes and the same loadings, conclusions were seen much better.

Those comparison flights were made in turbulent and moving conditions that enabled us to see how the gliders cope with the current conditions.
I have to say that at the same loadings the Pure is a half km faster at trim than the M4 .

In average conditions the M4 felt like more of a floater,comparing to the PURE at the same loadings, but still the differences were negligible because it couldn't separate the gliders apart the whole flights even when the conditions got weakened.

My own feeling when flying side by side and when there’s some head wind and strong punchy thermals, I saw the Pure get that spring upward climbs edge. Like I described it before, it climbs quickly and settles above your head and feels like time has stopped, waiting for the pilot to act.
The M4 needs a bit more time to settle above the pilot head, but still climbs brilliantly and has a comfortable feeling.

That characteristic of the PURE is shown in glides at trim, and especially when we flew both of them at first bar. The M 4 M/S hold the bar better and feels softer, but the Pure when settled have an amazing headwind glide.
They both could be equal in those glides, but my friend on the PURE was always ahead cutting through …For a race to goal, the Pure is a very competitive glider, and we both agree that it’s a very serious competitor.
