MARVEL |
The Marvel is a paraglider designed
for pilots who demand the highest performance in the
EN-C category. This high performance serial class
paraglider benefits from new technologies inherited from
the Magus XC2. It is a pleasure and fun to fly. If you
don’t believe this is possible; then try it.
Intensive testing resulted in a well balanced glider
with simple take-off characteristics and easy behaviour
during extreme manoeuvres. The glider is light, weighing
just 5.48 kg for the medium size. Stability in flight
gives confidence, and the extraordinary handling
combined with sporty agility will satisfy every pilot.
The Marvel is a glider which is absolutely confidence
inspiring and without stress during long flights and
thermaling. The Marvel features high stability
throughout its speed range. The glider is undemanding
and easily controlled in real mountain conditions.
The smooth shape of the airfoil nose is maintained by
Mylar reinforcement combined with plastic rods. It
features thin risers; a sporty silhouette with an
elliptical form; and has an moderate aspect ratio of
6.48. The top lines are thin unsheathed Aramid
competition lines. Bottom lines are sheathed Edelrid
Kevlar lines. The split “A” risers facilitate Big Ears.
The positioning of the outermost “A” line makes
progressive closure easy. Opening is smooth and
predictable. The bunching system on the trailing edge
gives precise handling with outstanding climbing
performance. The moderate brake pressure allows pleasant
turns and pressure increases progressively toward the
end of brake travel to offer safety reserves. The Marvel
is equipped as standard with brake handles with a swivel
and magnetic clips. Velcro closures on the wingtips make
access easier to remove any sand, grass or small stones
from the glider.
With the performance benefits of thin risers, reinforced
leading edge, thin lines and a high aspect ratio the
Marvel should appeal to both competent cross-country and
serial class competition pilots. The glide ratio
combined with agility and sporty handling makes the
glider really lovely.

The Marvel is manufactured using the paragliding
industries well established lightweight material
with excellent durability; Skytex 40, from
Porcher Sport (NCV). Because for any glider, the
part that always wears out first is the leading
edge, we use Skytex 45 with evolution coating
E85A for this. For the less stressed areas of
the sail we use Skytex 40 with E38A coating. For
the supporting and diagonal ribs we use Skytex
40 with “hard finish” coating E29A. This gives
the advantage of a sail that is both lightweight
and very durable. |

MAC PARA’S
DESCRIPTION
The Marvel offers sporty agility and amazing
performance in the EN C category. It is the perfect
glider for pilots who want performance and XC
capability.
BACKGROUND
Mac Para are one of the long-time established brands
in our sport. They have had a consistent range of wings
over the last few years: from the Progress starter wing
to the Magus XC Serial Class racer with the Magus as
their Open Class flagship.
Their Sports Class wing has been the Envy series,
currently in its second incarnation. We tested the Envy2
back in issue 127 and found a wing that, “was no more
demanding than most 1-2 [EN B] wings,” but that had, “an
extra dose of performance”.
When at this year’s Kossen Testival Mac Para’s designer
Peter Recek told me that the proto we were watching
coming into land was their new project that was being
designed to fit in the EN C above the Envy, I was keen
to get a chance to fly it.
Peter said: “When we were testing the Magus XC2 we
realised with a few modifications we had the potential
for a very good EN C wing.
“With the Marvel we are looking to achieve similar
performance to the Magus XC2 combined with great
climbing ability and lovely handling.”
CONSTRUCTION
As so often seems the case with Mac Para wings the
design of the wing is very clean and classical. The
aspect ratio of 6.48 is nearly in EN D territory;
Ozone’s M4 has an AR of 6.5. This high aspect ratio
combined with a cell count of 75 and the familiar Mac
Para colour scheme help create the impression of a sleek
racy wing.
The sail itself is made from Porcher 45g/m2 on the
leading edge with 40g/m2 used elsewhere. This along with
other savings have helped Mac Para keep the overall
weight down, which has to be good in this class of wing
that will often be used by travelling adventure pilots.
It seems that these days you can’t have a wing without
nylon rods in the leading edge and the Marvel follows
this trend. The rods go back a good 20cm or so along the
chord; not as much as some but more than others. The
leading edge is entirely open except for the cells in
the tip.
Going to the back of the wing one modern innovation is
conspicuous by its absence: Peter and the team have
opted to go for a classic trailing edge rather than use
mini ribs.
The risers are made from suitably thin webbing, which
add to the racy feel. The design is relatively simple
with just three risers – from each of which the three
main lines come. Only the A riser is split. Three
sheathed main lines are attached to each riser with the
stabilo also attached to the B riser. Although the wing
has three lines on each side it isn’t a true three-liner
as the C lines split to two tab positions in the centre
of the wing. The upper lines are all unsheathed.
The speed system makes use of large Harken pulleys and
also features a step-down ball making half-bar easy to
find. The brake handles are standard webbing handles
attached via magnets and have a swivel to prevent line
twisting.
The wing is available in four certified sizes covering a
weight range of 70kg to 130kg. There is also a Marvel 38
with a weight range of 140kg to 185kg but this is
uncertified.
LAUNCHING
During the test period – a three-week trip to Nepal
– I launched in a wide range of conditions. The wing
proved to be easy to launch whether reversing in windy
or thermic conditions, or forward launching during the
day’s last gasps. All my launches saw the wing rise
smoothly and it took little controlling once overhead.
IN THE AIR
As soon as you are in the air you get a true feel
for the lineage of this wing. If you have flown any of
the new breed of EN D wings it will feel very familiar.
You will have the same taught feel of a single wing
cutting through the air. However, it all just feels that
little bit more relaxed – but without feeling dumbed-down.
The wing is engaging to fly and there is a good level of
information on hand to help you find the best lift. But
all the information is passed on smoothly and there are
no sudden surges or jumps to unsettle you. Undoubtedly
this wing needs a little more piloting than a lower-end
EN C wing, but the information fed to you means you will
naturally fly the wing actively.
The Marvel uses bunching in the brake system where the
brake lines go through loops on the trailing edge that
are pulled together with the initial application of the
brakes. This helps the wing turn quickly but flat.
Indeed this wing doesn’t exhibit large amount of roll –
that isn’t to say you can’t get it up on a wingtip by
applying a measure of weightshift as well as increasing
the amount of brake.
The lack of roll may mean it is less ‘exciting’ to fly,
but it makes for efficient climbing. The brake pressure
itself isn’t high but starts to ramp up as you get
towards the stall point, giving plenty of warning of an
incipient spin.
ON LOCATION
I took the wing to Nepal during the test period. In
the stable conditions of Pokhara the wing climbed
effortlessly through the crowds. Once into the bigger
hills and stronger thermals a bit more brake and
weightshift got it easily centred. In thermals the wing
was easy to keep locked in, and the smooth transition
between flat and banked made it easy to stay with the
lift as you climbed through the various layers of air. I
found the handling so natural that I could leave the
thermalling to my subconscious, allowing me to plan the
next move or simply to enjoy the view opening up around
me.
When it’s time to head off on glide the wing shows its
top-notch performance for the class. Gliding at trim the
wing feels fast and efficient, as you would expect. With
the large pulleys the speedbar is smooth and doesn’t
require much force to apply. Going to half-bar gives a
good increase in speed with no real noticeable increase
in sink rate – indeed there is no steep drop off going
pulley to pulley. The wing feels reassuringly solid on
bar and cuts through the air nicely. It’s possible to
keep in touch with the wing through the C risers but I
found very little need to correct the wing on glides.
Glide performance is always hard to put meaningful
figures on, but from the glides I made on this wing I’m
confident that it will put a smile on your face.
CONCLUSION
In a year of confusion in the world of Open and
Serial Class racing we may well see a lot of pilots
turning to the Sports Class to get their racing kicks.
I’d be very surprised if we don’t see the Marvel amongst
the wings at the front of the pack. When not racing,
take it to the hills for big days out or even further
afield for some adventure.
I’ve long loved the Sports Class and this is a fine
example. It combines really well-crafted handling and
overall performance that you expect from higher class
wings, with an extra level of safety that gives you that
bit more confidence.
