Mentor 2 S & Sprint Evo S, & Rush 3 M
Most easy to fly:
Climb rate in weak conditions .NO head wind (<0.2m/s)
2-Mentor 2 =Rush 3 if equally loaded
Climb rate in weak conditions with 15 km/h head wind and thermals (<0.2m/s)
1-Mentor 2 S (Efficiency showed)
2-Rush 3 M (have to be loaded)
3-Sprint Evo S ....
Climb rate in strong conditions:( With strong valley breeze)
The Rush 3 (loaded) and the Mentor 2 S have a good climb ,but i sensed an efficient forward thermal bite for the Mentor 2 as it can fit itself inside the core better .The Sprint evo will struggle a bit in strong valley breeze.
Climb in strong thermal (No drift) .. I wish all thermals are like that Wink
All are equal in climb with the tendency of the Sprint Evo to stay inside the stronger part of the thermal,and could have the edge in those particular conditions.
Glide in calm air :
1-All very close
Glide in turbulence and head wind (Equally loaded)
This was done after many flights (now I am more convinced)
1- Mentor 2
2- Rush 3 (Should be 90% loaded to achieve good results)
3- Sprint evo
Overall efficiency in racing upwind:
1- Mentor 2 S
2- Rush 3 M
3- Sprint Evo
Glide at second bar in turbulence and head wind:
The Rush 3 and Mentor 2 are equal if there 's a little head wind ,with a stable profile for the Rush 3 at bar. The Mentor 2 seems more efficient when the head wind is blowing.It can cut through with ease.
I have spent 3 whole days taking off and landing and swapping gliders, to determine what glider is the most suitable for all conditions. It is the best way to find what glider can get through those same conditions better.
The 3 are excellent gliders, The Evo has a very nice handling, the Rush 3 has a soft feeling underneath it. Pilots looking for performance and handling in a mild way will love those two. The Rush 3 M has to be loaded to cut through head wind. The Evo has a big profile that doesn’t penetrate the strong head wind like the 2 others.
The Mentor 2 S still has the most sharp and precise handling, with “usable” performance in all conditions, no matter if you have a head wind, strong thermals, the Mentor 2 S @ 95 will cut through nicely and powerfully. It does have more roll response than the two others, and feels exactly like a high end EN-B glider, but for a good EN-C or D pilot, it is the cherry on the cake. Efficiency at its best in the EN-B cat.

My ever first school glider 20 year ago was a UP Flash. I still remember the red cloth with multicolor design on the edge, that feeling and that smell of the tissue with this arrow logo going UP in the sky. Uli Weismeyer legend pilot ,Richard Gallon were on UP gliders at the time and the brand was very strong in the competition scene with their Katana ‘s and later on with the Gambit, escape with Oli Russell, Steiglar ,Brinkeby...
I flew quite all the UP range, from Stellar, Vision, vison classic, Soul. All the Summit range ,nearly all the Kantega range,and trango’s and targa’s and all the tandems…
The firm feeling under an UP is very familiar to my mind.
Now here’s the Summit XC2 ,and I’m just waiting to pull on the A risers.
Ballasted up to 100 ±102 on the M size with an Impress 2 harness, the launching is natural and easy, the glider comes up as a whole piece.
At first the factory settings on the brakes was long, I landed and shortened them a bit.
From the moment I was airborne, a sensation of confidence inspiring is clearly showed. I was impressed by the easiness in flight of the XC2. Very tamed with neat behavior, well-tensioned and balanced glider. Just the necessary feedback to show the thermal direction.
First turn showed a medium brake pressure, with fair agility, but doesn’t dive in turns.
Opening the chest strap a bit will make this glider very nimble and more agile. Turns are flat and the climb is its strong point. This glider is a killer in weak conditions. It can core every bubble without loosing the center of the thermal.
In strong conditions, the glider remains as a whole, and climb without any strange movements or oscillations. It is difficult to miss any thermal with this glider, unless you have some convincing excuse ;-) .
I gave the XC 2 to my friend Moni, and when he landed he told me that the XC2 is “much more” mellower and easier to fly than the Mentor 2 EN-B glider. I agree.
Big ears are easy to hold, stable and reopen by themselves. The glide ratio of the XC2 is well enough among the EN-C category.
The accelerator has medium pressure, much like the Trango 3, and the speed really increases by more than 5 km at first bar! Very usable and efficient.
Actually the overall feeling under it reminded me strongly of the UP range designs I have flown before…
Conclusion: This glider is aimed for all EN-B pilots who want to step into the EN-C category, but still having a large amount of safety and I think it could be also much easier to fly than some!!
EN-D pilots stepping down will find in the XC2 a quiet sanctuary to fly long xc’s wondering if they are on a sofa or in the air. :-)
OZONE RUSH 3
After flying the Mantra 4 and the Delta before I realized that OZONE has found a very comfortable profile with excellent performance. Now after the NOVA Mentor 2 has raised the bar for the new EN-B’s, I was intrigued to see what the Rush 3 would be like.
Standing on take-off with 96 all up weight on the M (85-105) size. Launching is easy and the glider lifted me quickly into the air.
The brakes travel is the same as on the Delta (Typical OZONE) Long brakes, soft very easy to steer with an average to good turn radius.
No matter what the conditions will throw at you, nothing will bother the calm attitude of the Rush 3.
I could describe it as “being on rails (stable) with rubber wheels (Soft) ”.
The same day I flew the Mentor 2 and the Sprint Evo, then again the Rush 3.The most dampened glider was the “Zen” Rush 3.
I am now more than convinced that OZONE has found something really special in those stable profiles.
The climb rate of the Rush 3 is really good at my weight load. Very close to the Mentor 2 .All you need to do is lower the brakes into the thermal…. No complications and corrections!
If the Rush 3 is loaded near the top, then the Mentor 2 with same loadings has the edge on climb, and this is because of the more lively profile of the Mentor 2.
Big ears are easy to make and are stable. The accelerator is also smooth and light. A real delight to use!
The moment of performance into wind and turbulence has come. Later, I gave the Rush 3 to my friend @ 102 all up, and I flew the Mentor 2 S @ 94 all up.
After many glides at trim and at first bar, we are both convinced that in calm air they could be “equal”…BUT, in head wind and turbulent conditions, a slight advantage was on the RUSH 3 !!!.
Let me explain: The Mentor 2 is an excellent glider but moves more in the air, and that’s a good thing for the educated pilot. The Rush 3 is more stable, so when on long glides into the thermals, wind, turbulence…the profile of the Rush 3 is keeping the wing on rails. It didn’t loose the glides.
The Mentor 2 move more and, those movements which are small but do react to the profile (roll and pitch) and make it loose a bit in long (air moving) glides. Actually in down wind glides they are practically the same.
Conclusion: Among the new EN-B’s, I have tested, the Rush 3 stand alone in comfort in flight and its performance and easiness in the air is extraordinary.
After 3 hours of xc flight in turbulent air, I landed on take off to take another glider and my mind was still fixed on the Rush 3.
If you want an EN_B glider, but stressed by work, daily duties and tired but willing to go flying without the extra stress, then the Rush 3 “is” the choice.

After the success of the Ozone R-10 series, a big majority of pilots were waiting impatiently for the birth of the M 4. Knowing also that OZONE has a very efficient marketing team, the M4 was keeping almost every interested pilot wondering what the M 4 would be like.
After I tested the Delta, l knew it was on top of its class, but I lately realized that it was the easiest one to handle, and has that comfortable feeling that could be mellower than some new EN-B’s.
I was impatiently waiting for the M4, to see if that feeling of comfort is still on the OZONE menu. And it came….
Plastic inserts on the leading edge, much like the Delta construction, which look a very simple and nice finish.
Heavy rain and high winds kept the Mantra 4 in a bag for a week.
Some kiting in strong wind and soaring gave me an idea of a very homogenous and balanced glider.
Today was promised to be good so I am standing on take off ballasted up to 100 kg on the ML size, with my usual flying friends.
Conditions of the day were a bit windy and turbulent at the beginning and smooth at the end with nice thermals up to 5m/s and high ceilings.
Take off is easy, and needs a bit of brakes to stop the smooth forward surge.
The brakes are a bit long and the feedback is felt by the brakes and sometimes by the harness in a “smooth” way.
Inside the thermals the glider have very different behavior. With the Impress 2 at ± 50 cm open chest, I could find that:
-In the strong “smooth” ones, the glider enters them quickly and climb like a devil, but “peacefully” .The turns in those conditions are very nice and you feel like the glider is leaning toward the thermal .A touch of brake is needed at the opposite side and the glider can turn on a dime. I felt that is better not to break much the other side, so when I let it fly, I felt that it cores best, unlike the Delta that needs a bit of brakes to climb best.
- In the strong but turbulent thermals, the glider needs to settle a bit before I could turn it. It is not that precise to my wing loading. But in this configuration the glider is the most comfortable glider in the EN-D category I did test to this day. It is like you are driving a “Limousine” and it shows to my eyes a real genius behind those very performing and comfortable gliders.
-In moderate broken thermals, I felt that the glider is waiting for me to react .It is like watching over me and not going anywhere. It remains inside the bubble waiting to be smoothly steered into it. And this is very efficient because it won’t go away and dive beyond the thermal.
-In weak thermals, at my weight it could be very efficient also. But I am satisfied and more of that will come soon…
NOW are you all waiting for the performance comparisons? ;-)
We did many glides into wind with the Boom GTO M loaded at 105 (Video in process soooon !) and F I N A L Y, I found a better gliding ability for the Mantra 4 that is visible to the eye!!
I felt that it was the first time I am flying a glider who felt ridiculously easy to fly for an EN-D, but has a comfortable advantage in performance.
The trim speed of the M4 ML loaded at 100 kg is faster than the GTO M loaded at 105 !
The M 4 is a glider that floats better into wind .The accelerator is smooth and efficient at first and second bar, pulley to pulley fully usable!
Big ears are stable and easy to induce. They reopen by themselves.
I have landed and felt like I was awake after a yoga class. “Serene”
More tests will be soon made with lots of videos. But I can confirm that OZONE has done a sublime job with the M4.
Conclusion: OZONE has done it! Comfortable, top performer, easy to manage, well-balanced glider!
My only wish is that the brake travel could be made shorter, more precise like the R10 to be able to core every mosquito thermal promptly. But i am very happy to have flown and tasted this beautiful powerful and yet humble glider.
Waiting to get the MS size for a test flight soon.

GIN SPRINT EVO
After leaving EDEL in 1997,Gin founded his own factory GINGLIDERS and with the success of the Boomerang 1, he has made lots of head turning toward the brand. Hans Bollinger world champion at the time (Ex-ADVANCE ) has left to join GINGLIDERS.
Some years back, we could see 9 boomerangs on the top 10 .
Over the years, too many futuristic designs have emerged, from some legend designers who are pilots and passionate for the sport and one of those is Gin himself.
Unpacking the Sprint Evo, will surely lift your eyebrows. For an EN-B glider, it has plastic inserts on the leading edge and also on the trailing edge !
Big cells are clearly seen. It has four risers, and has five attachment points a,b,c,d,e
on the canopy !.
Knowing that all other designers has gone to the three-line concept, I was curious to see what this glider would be like in performance versus the best EN-B of the moment.
Launching couldn’t be easier. Hands in the pocket style ;-)
Quickly airborne, and first turn………My smile has even passed the ear to ear comment!
What a turn! With a moderate to light pressure, crispy, prompt, linear response, it is the most beautiful feeling of turn in the EN-B category I have flown for a long time.
The glider cores incredibly the thermals like working with a screwdriver.
For my personal taste, the handling is the most important quality in a glider, and the Sprint EVO fulfilled my expectations for superb handling.
To add to this feeling an excellent climb rate is putting the EVO on top of the stack!
The climb rate is more than efficient and I have still to believe it….I think it has the edge for the EN-B category I have just tested. May be because a good pilot can place it in a surgical way whenever, wherever he wants, with the ability to brake and slow the glider in the air.
The Sprint moves in roll a bit less than the Mentor 2 and a bit more than the Rush 3.
The accelerator is soft and when pushing it, the glider is more taught stable and fast.
The performances seem very interesting especially on bar !, but I need more time to evaluate it, and videos will come soon.
