GRADIENT ASPEN 2
by Greg Hamerton.
Greg has been flying since 1992 and has flown over 100 wings. He
prefers responsive handling and agility but rates passive
stability highly as he enjoys taking photographs and snoozing whilst
gliding.

Introduction
Gradient has a reputation for top performance with their Avax
competition gliders often in the lead gaggle. Their wings are known for
speed and performance in a straight line, but sometimes don't have the
most finesse in a thermalling turn. I was interested to see
if their latest sports class (DHV2) release would have refined the
handling of its predecessor, the Aspen.
Construction
This wing is noticeably lighter than anything in its class that I've
flown. The pack volume is small, and it weighs in at only 5.2kg on my
scale (Gradient says 5.4kg). For
the bivouac pilot, hill-climber and wilderness
tramp this is great news.
Standard construction gives only four risers (no split A's)
and thicker webbing than necessary. The brake loops
have a thick insert and are reasonably comfortable to use.
Nice stuffbag - slightly bigger than needed so very easy to pack into.
The top cascade of lines is unsheathed, which gives you a slight boost
in performance and reduces weight without much sacrifice, except I
found that small sticks like to tangle in the unsheathed lines.
Launching
Because it's so light it's easy to launch in light winds. In strong
winds it smacked up, steady and straight and simple.

Feels calm and is quite stable |
In the air
Moderately agile and moderate energy, there is nothing 'hot' about it.
Now and again I wanted to turn tighter than it was turning, but there
is a benefit to the calm turning behaviour - it makes you fly
efficiently, and you never get caught out by dropping your inside
wingtip too deeply in a turn. This is the kind of wing that will teach
you to fly while you're doing your first cross country
jaunts. Keeping the wing overhead in rough thermic conditions
is
easy - this is not a particularly agile wing, and yet it is responsive. I very seldom had to use
the outside brake to control the roll rate, as the wing will turn to a
certain amount and generally not go much further.
Performance
The Gleitschirm mag measured it at 8.7 glide ratio, putting it right in
the top group of the 2006 DHV2 class. In my
experience the glide is not quite that competitive, but it will
certainly keep you very near the leaders.
You might be able to find something with slightly more glide amongst
the 2007 releases, but it is
always the combination of performance, safety and handling that
matters, and when you consider how calm the Aspen 2 is, and
how reassuring it is to fly, you'll see that this is a great
all-rounder.
Safety
What a nice wing. I tried to induce big front tucks, but these mostly
resulted in smaller tucks than I expected. The recovery is simple and
spontaneous.
The brake travel to stall point is moderately short, and the brake
pressure doesn't increase that much, so you should be careful not to be
too heavy-handed on this wing, and to allow stalls to recover with a
hands-up approach.
Asymettric collapses were impressive. Often they would smack out
without really crumpling, but those 50% collapses that folded under
didn't turn the wing much. Even when leaning into the collapse, I
didn't see the wing turning more than 180 degrees, most of the time it
just flew on straight. This is fantastic behaviour for an xc wing,
because you can often be up against a turbulent ridge and don't want to
be swung in towards it during a collapse.
Big ears were awkward to get in because there's no split in the A
riser, which is a pity. Once they are in its easier to roll the glider
and get rapid height loss with wingovers.
The approach to spin average and fairly easy to induce. It's simple to
recover from a spin if you go hands up at once, but the spin itself is
fast, it whips around.
The recovery from parachutal stall and full stall is the nicest I've
experienced, which is a big plus for acro. It pulls out with a moderate
pitch.
When considering a glider for bivouac use, I always ask myself, "Would
I be comfortable flying this wing without a reserve?". With the Aspen
2, yes. No problem. It is reassuring and has no worrying weak points in
the way it flies. Its tendancy to dampen out rolls and pitches make it
safe.
Speed
I've only managed to race against an equal-weighted pilot on a Swing
Mistral4 (DHV1-2), and we were neck and neck. Glide was a fraction better on the Aspen at trim speed. I'd
say the Aspen 2 flies at just over 50. The speedbar travel is 16cm and
it is not a linear progression - the A's and B's are kept close
together (for stability) which usually degrades glide performance
slightly.
I did have a few collapses on speedbar in grumpy air, so the
wing isn't rock solid on bar, it feels lightweight and in need
of a bit of attention, but its calm nature means you don't have to
worry much.
Summary
I could get over the top of the wing with wingovers but it took a while
to build up the energy to that point. The wing prefers to dampen out
rolls and pitches and will absorb the energy very effectively. This
makes it a very reassuring xc tool. If I was planning any kind of
adventure or trip where I wanted my pack weight and volume to be small,
this is the wing I'd take. It's got good performance, nice handling and
robust safety features. Well done, Gradient, this is a well-designed
wing with a calm turn that makes a great all-rounder and is in the top
group of the class for 2006.
Additional Comments
I found the brake settings to be 8cm too short, which causes the
trailing edge to be slightly pulled down on glide, more noticeable when
on speedbar. It also makes launching with crossed-brakes tricky. I
would recommend lengthening the brakes slightly from standard
position. Gradient decided to do shorten the brakes after
many Aspen1 pilots complained that their brakes were too long. |

Aspen 2 has a good glide performance.

Colllapse! Recovers easily, returns to centre

You don't get a hook turn, when you steer, you veer
