FIRST
IMPRESSIONS
A full review of a paraglider takes many days of flying, various types
of conditions, a trusty camera and of course lots of experience to make
useful comparisons. But what can be learned about a wing when
you
only test it for a short while? What are the most important
things to look for? What do you compare and consider once
airborne?
First things first, get your hands on as many gliders as possible and
fly them every chance you can. The more wings you fly and the
more weather you fly in the easier it becomes to discern a great
thermal from a great wing (or rotor from a reject).
Then when you have an opportunity to fly something new, in my case an
Airwave Mustang (L) you can focus your attention on the following.
CONSTRUCTION
You can see or feel what a glider is made of in an instant.
If
someone hands you a wing and says “can you keep an eye on this while I
take this phone call / go to the doctor / run to the loo” check the
fabric. Gelvenor feels smooth and rubbery. Porcher
is
thinner and more crinkly. All certified gliders pass a load
test
so they must be strong enough. Gelvenor is heavy but holds up
well in the harsh South African sun. Porcher is lighter
weight
but be careful if you tend to land in thorny bushes or on fences.
The Airwave Mustang is made from a mix of fabrics. The
leading
edge is Gelvenor at 50 gr/m. This heavy duty fabric extends
from
the cell openings back about 25%. The tail 75% of the wing
(top
and bottom) is made from Porcher which weighs only 39 gr/m.
Other manufactures have made wings with Gelvenor on top and Porcher on
the bottom. The goal is to make a wing that can handle the
sun
without all the weight. This split from front to back makes
sense
to me (since the leading edge always gets baked) and the weight is
pretty low. The medium Mustang weighs only 5.6 kg.
Unless the lines are unsheathed you won’t be able to tell what they are
made of. If it is a competition glider, be thankful for the
load
test. They always look too skinny. Ask if they are
not too
old. If it is a normal, serial class wing don’t go pulling
apart
the stitching. It will be the last demo / loaner wing you
get! Ask the dealer if you really want to know what the lines
are. The Mustang is made with Kevlar lines. I only
found
out when I cut one on a rock.
If you bust a friend’s glider, get it fixed
properly. He’s
going to find the duct tape eventually. And don’t try to
stitch
anything with dental floss. You can smell the mint from a
mile
away!
Risers are pretty self explanatory. Things to look for on a
new
glider are the Brummel hooks if you need them; whether the speed bar
line is between the A/B riser or in front of the A and if the brake
handles are nice. The Mustang speed bar line is in front of
the A
riser and is as long as usual (with Brummel hooks). The brake
handles are webbing filled with medium density foam. They are
attached to the riser with magnetic keepers.

LAUNCH
If you are about to take off from Table Mountain or some other
dangerous cliff face, you may want to ask if the wing has any “funny
tendencies”. Otherwise, take off as usual and see what you
get. I prefer not to have someone remind me to pull harder,
longer or tap the brakes or whatever. I like to launch a new
wing
just like I always do and see for myself what happens. If I
get
dumped or dragged, the dealer/friend can have the wing back sooner
rather than later!
When I launched the Mustang the first thought in my mind was “Wow, that
was really easy.” Subsequent launches were the same
way.
When I went to a local field in a gusty South Easter to get some photos
I was still impressed with the ease of launch.
BRAKES
Some people, myself included, mess with the line lengths.
It’s a
good idea to ask if the wing has been modified. If it has,
you
can forget about the DHV rating. Shorter brake lines (the
most
common change) affect everything from launching to maneuver recovery to
towing characteristics.
The Mustang still had the factory settings. The brake
pressure
was average, progressive and didn’t really cross my mind.
When I
wanted to turn, the glider turned.
WIGGLES, WOBBLES AND OTHER HANDLING
What you really want to know is how a glider feels in the
air.
Technical manuals can’t convey the feeling. And most dealers
are
biased. So as soon as I have some clearance I like to wiggle,
wobble and see what falls down.
Wiggling from side to side in your harness with no brakes will tell you
a lot about roll stability. I’m talking about big weight
shift
here. Think about how fast and hard you would throw your
weight
to the side if you thought your camera just fell out of your harness
pocket. Do that a few times and see what the wing
does. The
more wings you’ve flown the better your references will be.
The Mustang was more sensitive to weight shift than average – at
first. With just weight shift I was able to swing through
some
mild wingovers. Gliders that are easy to roll with weight
shift
normally provide lots of feedback in thermals or rough air.
At
least that is the theory, and all one has to go on if your test flights
are short. How much wiggle is ideal is a matter of choice.
When I tried to really crank-n-bank the Mustang there was a definite
hesitancy. The roll rate and turns felt quick and coordinated
for
the first 60 degrees then sluggish after that.
One can also feel a glider’s pitch stability with a little
“wobble”. Alternating application of speed bar and brake will
quickly indicate how much pitch is allowed on a wing.
Launches in
strong wind also give a good indication of how likely a glider is to
surge forward. The Mustang was well behaved in this regard.
I AM HIGHER THAN YOU ARE
It’s hard not to like a glider when you are soaring higher than all of
your mates. But don’t be fooled if you are lighter on the
wing
than they are. Little things like ballast, flying posture and
pilot wind drag all impact performance.
For meaningful comparisons I like to scratch in light lift next to a
hill. Every meter lost in a turn is noticeable when terra
firma
is right next to you. As you swoop past the hill your sense
of
speed will be more pronounced. Your rate of turn around a
tree
(or into it) will be very clear. Your bank angle while
turning
can be compared to something stationary. In general, your
senses
will feel more switched on and many comparisons are easier when next to
the ground.
I had an opportunity to scratch on the tiniest of hills in the lightest
of lift while flying the Mustang. I stayed up when I didn’t
expect to. I zoomed past rocks faster than I probably should
have. And I had a ball while testing out the new
wing. When
it comes to performance, this is what I like to compare.
Numbers
on a web site don’t fly. But the numbers on my vario were
bigger
than those of my mates.
WHEN THINGS GO WRONG
Seeing what a glider does after a full stall or other hair raising
maneuver is the toughest part of a glider review. Most pilots
simply aren’t going to try this for themselves. And why
bother
when someone at the DHV or Afnor has already done so?
The best (not the safest) way to find out how far or hard you can pull
before a glider spins or stalls is to actually do so. But if
you
don’t have the height (or the insurance) there are other
choices.
You can spin or stall a wing an inch above the ground. You
won’t
get any practice with recovery, but you will learn much about the stall
or spin point.
The most useful maneuver to check when borrowing a wing for a short
time is the asymmetric collapse. It is the situation you are
most
likely to encounter when flying and it will tell you what to expect the
next time you fall out of a nasty thermal.
The Mustang reacted more mildly than expected with normal asymmetric
collapses, but quite actively when accelerated. Turn rates
when
relaxed in the harness and not counter-steering were about 70 degrees
and 180 degrees respectively.
If one has enough time and height, front tucks and B-line stalls can be
checked too. If you are skilled at the exit, you will want to
spiral every wing you fly.
I found the Mustang entered a spiral with ease. It was easy
to
slow down and exit. Building up lots of energy for acro
required
some work.
WHEN YOU HAVE TO GIVE THE WING BACK
Before returning that demo wing, try to make the following comparisons
to whatever you fly now. Does it launch easier? Is
the trim
speed or maximum speed any faster? Did you feel at home on
the
wing instantly, or do you expect to “get use to it”? In
particular, did the wing turn the way you like it to? Some
like
to crank-n-bank and some like to keep it flat.
Overall, I was impressed with the Mustang. The ease of launch
and
weight are really strong points. It felt about as fast as
most
gliders, but I did not get a chance to check this carefully.
I
felt very at home and at ease while cruising around. Nothing
on
the glider needed getting use to, although I would not recommend the
wing for acro. Unless maybe you get a size too
small.
These were my first impressions of the Airwave Mustang, as well as what
goes through my mind while testing (playing). If have an
opportunity to fly the Mustang, see if you agree. If you test
fly
something else, I hope my suggestions come in handy. |

Launching - Wow, that was really easy!
