Russian Standard. Marlin-30.

Test conditions.

Tested fully serial Paraavis Marlin with trimmers. Size - "30". Take-off weight of test-pilots (110 and 115 kg) was in accordance with recommended weight (90-120 kg). Harnesses: AVA Спорт Sprinter. Flight conditions: wind 5-12 m/s, no thermal activity, turbulence low, temperature 0…-1 C. Flights were realized in Rubolovo with passive towage.

Design and appearance.

D_i_m: Complicated construction inside the canopy, intricate risers with trimmers and rolling straps. Triumph of space-based technologies. Speed also intricate and short-stroke, this is comfortable. At first look, no more technical tricks were found, think it's right. Moderate aspect ratio flat, арочность as well. Four rows of lines, traditional and quite thick. Accurate ears beautifully, without folds, turn down. The glider looks like short-cut Paraavis Dart.

Start

D_I_M: Easy and fast. Canopy has small tendency to overfly pilot, but can be stabilize by brakes also easily and quickly. Due to fast launch, canopy simply has no time to fall on side, but in case it was happened - easy to correct. In strong wind ears strive to fly up the first, but centr-section don't lag too much. For launch - grade: four with advantage.

Alaska: Can't say, that launch is something difficult. The loading of A-risers is big enough, feedback of risers during the front launch is good. The only one thing - glider like to be rise strictly against the wind.

Behavior at towage.

D_i_m: Situated strictly over the pilots head, no shift back at all. Clear reaction at brakes, little worse at weight. Jerking of trailing line to be damped by yourself, because canopy like to crawl up-and-down. Direction holding is good, no tendency for swinging at bank. Good.

Flight, maneuverability.

D_i_m: I like it! Even small turbulence - bum-bum-bum at the harness. Wiggle over the head. Pi-pi-pi at the variometer. Very informative behavior. Even don't know, whether it is necessary for Standard. But - nicely. Steering by brakes and weight shift easy and quickly, but necessary to control the speed. Slightly release the brakes - acceleration and you lose the altitude. May be the trimmers to be used more actively - but the pilots are spoilt today, about the trimmers precisely heard not all.

Feedback.

D_i_m: High, even too much.

Thermal spiral.

D_i_m: Possible, nothing difficult. Although sinking is fishily high. This is with out the trimmers. Didn't test with trimmers. Nothing special.

Flight with applying of speed system.

D_i_m: Amazing! Marlin rush as crazy! Such speed is unusual for this part of market. Subjective - very fast. Unfortunately we didn't effect the measurements due to the very gusty wind. At maximum speed the center section starts to show nervous first. Outer cells keep the fullness and tightness, but memory about the dashing front collapse compels to release slightly the speed pedal.

Alaska: With applying of speed system Marlin draws in the lower edge of air-inlets, little ripples appear at the center section. With external inputs, canopy start to flap slightly. Slightly similar as the ancient Navigator.

Landing

D_i_m: High-speed glider! Have to be careful at landing. The hover is strange. You can hover at the landing by brakes down, but this is not as usual. Let's say - not bad.

Descent helps

Spiral dive

D_i_m: Whiz! Active acceleration. Spontaneous exit, from sinking speed of 12 m/s, at any case. Ears didn't flap at all. Good.

B-Stall
Was not tested.
"Big ears."

Alaska: Ears seal, for recovering necessary to pump by brakes and energetic weight shift in harnesses.

Extreme conditions.

Asymmetric collapse.

D_i_m: Good way to tickle your nerves - to have asymmetric collapse at Marlin at the cold January's morning! Hop - and half of the wing fall down like a spade! Yo-ho-ho! As Number One teach, dive for the canopy into spiral, and after as recently 60 meters at vertical with whiz, pass the perigee and fly up like a bullet! Are you trembling? This is OK. This is not the Tequila with Sprite, this is real neat Russian Standard with out any ice, i.e. 40 degrees and minimum 0,7 litre, as great Mendleleev bequeathed. What to say? No chance to catch us!

Alaska: After 50% collapse the glider same moment go forward and sideways, but simultaneously start to open very energetic, recovery - after one turn. If pilot will start to compensate rotation and pump collapsed cells, the rotation can be reduced to quarter of turn. As per my feeling, even the asymmetric collapse will take place, the canopy will collapsed in one moment and with a big closure.

Front collapse.

D_i_m: Let have some fun! Pull down A-risers. Oh, Jesus fuck, what happened? From the Earth looks like Big Ears, but for the pilot everything like full stall. Everything flapping, flattering and sinking faster and faster. Counting. Ein-zwei-drei - polizei… canopy don't hurry to recover and hands, automatically, effect one energetic pump, which is sufficient to recover. Forward surge, acceleration and everything finished. Less 40 meters. Ups…

Spin from thermal spiral.

D_i_m: Ideally, like shift of guard honour at Red Square. Surge are deep, but with out collapses. Excellent!

Conclusions.

D_i_m: I feel pride! It is not so often to feel pride, especially when it is pride for the country. For the Motherland! The country where live the peoples, who flying on such gliders is unconquerable. As the owner of tested glider says, that after Marlin, he feels himself like in slippers flying Vulcan! In view of speed, this Standard can give to the most of High-Performance gliders chance to know how deep the ass hole can be, it's cool! I like it! Also like that my old Proxy, have more or less same behavior, but Proxy has more mobility and hard in spin. On the other хэнд, Proxy is friendlier in view of asymmetric or front collapses. It's cool guys! Respect to Paraavis, that they didn't chose well-known way of production merchantable "barges", the only one advantage of such gliders - that they can't scare even the expectant mother. Marlin was not designed for cowards, and they will not buy it! Marlin - the glider for real pilots!
Now, as per my point of view, who can be the real pilot for Marlin. First of all, 100 flight practice minimum. Honestly completed SIV-course. 50 hours per year flight practice in hard conditions minimum (friendly dynamics doesn't count). Composure. Good skill to check the attitude and ability to use rescue. Target group: unambiguously not the freshman. I don't know the flight school where the pilots can receive the necessary skill of malignancy to fly Marlin. The experienced pilot, flying in hard mountain's conditions, at the edge of glider's features. Bladerunner, who will not afraid to start in 12 m/s wind. Samurai, who will be happy to saddle the thermal with 15 m/s at periphery.

Alaska: This glider designed for active and tough flights. High speed gives substantial advantage for tactics of X-country racing. Regarding the safety: glider demand from pilot to have very careful control of collapses.

Plus

  • Great speed in this class, as well as in some others
  • Easy launch
  • Good steering
  • Friendly recovering after spin.
  • Trimmers available

Minus

  • For the fighters, who will buy such glider, all the minuses are not important.
  • For all others - tough reaction and great sink after asymmetric collapse.
  • Iindistinct front collapse - slow recovering
  • Sinking - not a small.
