ALLEGRO

Test Allegro 22 (90 -110) loaeded at 104kg

Harness: Wani Light

Tested int : Mont Lachat, le Grand Bornand (FRANCE)

Time flew : 7h

A agile,

accessible & precise

EN C glider.

TEST ALLEGRO 22

Let’s start from the beginning:

THE DESIGN, LOOK AND

CONSTRUCTION FINISH.

The Allegro is the first EN C glider

from PHI, it has been designed by

the famous Hannes papesh. This

glider aims to be accessible with an

aspect ratio of 6.

The rods are relatively short which

allows a compact packing.

The line cone is surprising for the

level of performance of the glider.

Indeed the lower part of the

lines is sheathed which facilitates

disentangling and handling of the

lines.

Now let’s get to the heart of the matter:

THE BEHAVIOR OF THE GLIDER.

Unfortunately, I was not able to practice

ground handling long enough with correct

conditions to get a precise opinion but i

have a mixed feeling ... For me the ground

handling behaviour is the only weakness

I found.

The first impression reminds me the

behavior of the Tenor light with a fragile

leading edge that pinches when you pull

a little too much the A lines. Thus, if the

pilot pulls the A a little too much it doesn’t

collapse, but the upper and lower surfaces

approach, partially closing the cells, which

disrupts the rise..

Once you get used to the extreme softness

required on the A, the glider rises softly and

linearly without any surprise acceleration.

As a result, the rise can be done smoothly

and the temporization also. Even in stronger

wind it didn’t seem to tend to overtake me

and front collapse.

The contained aspect ratio of 6 makes the

glider fairly homogeneous although roll

management may be necessary (nothing

difficult for a pilot wishing to fly under an

EN C).

On the back launch, the semi-light

conception of the Allegro (Porcher Skytex

32 fabric) combined with the relative

fragility of the leading edge when pulling

the A’s made it technical for me. Indeed it

was difficult for me to feel the rise of the

glider and it positioning.

by this first handling of the Allegro,

especially the ground handling. I’ll have to

test it more in varied conditions to specify

my opinion.

The first impressions were therefore mixed.

However, this is not the first time that a

PHI glider gave me a strange impression

on ground handling, yet, I fly a Tenor that I

love in all other aspects !

So let’s move on to what got me

interested in the PHI gliders & the

Allegro ?

THE FLIGHT BEHAVIOR.

The allegro is surprisingly damped on the

pitch axis; even on deep spiral fast exit, the

pitch control is smooth (which surprised me

because I hadn’t found this characteristic

with it little sister the Maestro).This offers

good piloting comfort, it will not be

necessary to be scare of the dive in each

thermal entry and exit.

On the roll axis, the glider is playful and

agile, I would not describe it as unstable

because its behavior is easily controlled

and a symmetrical contact on the brakes is

enough to smooth the roll effectively.

On asymmetric collapses the glider reacts

well and reinflates immediately without

noticing any tie or other complications.

In summary, I was not particularly seduced

I also experienced an involuntary collapse when getting

out of strong thermal and the glider reacted healthily by

instantly reopening without changing course (a warning

for a positioning mistake).

The ears are easy to pull on and to maintain thanks to

the dedicated A-riser. They are stable and do not flap, the

reinflation is ease with a light pumping on the brakes.

One of the selling points of the Allegro is the accelerated

speed.

On the first bar it doesn’t seem to add more speed than

on another glider. However, it does not affect the structure

of the glider which remains very comfortable and stable.

On the other hand, on full bar, the acceleration and speed

achieved are impressive. There is a real feeling of speed

and glide.

Once again, the comfort of the glider, even at full bar is

surprising!

I was able to play serenely with the entire speed range

of the Allegro during my cross-country, a significant asset

when it comes to looking for performance.

Although the risers do not have handles for piloting with

the C risers, the linkage system between the B and C offers

a comfortable hand position; reassuring contact and good

piloting efficiency.

I am particularly demanding in terms of handling, which is

for me one of the most important criteria in choosing my

glider: I want to have a turn that allows me to set the glider

quickly and precisely wherever I want.

On this point I was not disappointed for a single second,

even in the middle of the PTV range, the turn was precise,

intuitive and pleasant. The brake is light on 2/3 of the

travel then harder on the 3 rd tier. The glider turns efficiently

as soon as the brake is applied.

The turn can be flat even on shorts turns radius if you keep

a small amount of outside brake.

When you use more of the brake range, it is easy to set

the glider on the edge: but it doesn’t tend to dive down

towards the ground, which is perfect for climbing in the

core of powerful thermals.

The icing on the cake was discovered during my second

and third thermal flights. I was conquered by a feeling of

support on the stabs, as if the wing tips offered a palpable

support on the air mass, allowing to correct the turn at any

time and transmitting informations on our position in the

thermal, awesome!

While thermalling I found no inertia; the glider bites into the

thermals by the leading edge, giving the sensation of being

sucked into the lift. Thus, entering thermals does not create

pitch mouvements, allowing to keep enough speed and

energy to effectively initiate a turn at all times.

In addition to having this big advantage of not suffering from

the inertia created by the nose-up movement, the suction

sensation gives excellent feedback on the air mass by gently

pulling us towards the center of the lift. .

Finally, as you will have already understood, the feedbacks

given by the Allegro are excellent. The Allegro transmits

and translates air mass informations into intuitive piloting

sensations..

Regarding the performance, the Allegro has a very good

glide, making the transitions easy and quick. This glide

allows an average climb rate in bubbling thermals or to fly

efficiently on long edges.

The combination of glide, passive safety, handling,

accelerated comfort and the transmission of information

about the air are all qualities that approach the perfect

balance to make the most of what the air has to offer us.

Conclusion ?

IT’S A CRUSH !

Despite the small reservation about the ground handling

that I will have to dig, the Allegro successfully fulfills all my

criteria.

À PROPOS DE L’AUTEUR

Jonathan Malvoisin, child from Saint Hilaire in

France (where the famous Coupe Icare stands),

began to play on ground handling at the age of

8 with his friends. He did his first solo fly at 14

with the « Little blues » generation.

Since then he flies between 60 and more than

100 hours per year, mainly cross country flights in

the northern Alps although he enjoys discovering

new spots as soon as the opportunity arises...

He enjoys trying new gliders whenever he can

and has a fine and precise lecture of what he

expects. He is passionate and he thoroughly

studies the qualities and defects of each material.

I immediately felt comfortable, safe and efficient under this

new EN C which will certainly follow me on great adventures!
