BEFORE YOU BASE, SKYDIVE.
BEFORE YOU GET TOO CRAZY WITH YOUR ATC, TRAIN!
Even our most experienced team pilots need many skydives (10, 20, 30+,
perhaps!) before they feel comfortable and confident in new wingsuits.
These are guys with 10+ years of experience, thousands of skydives, and
over 1000 BASE jumps. Please take your responsible progression seriously:
skydive your wingsuit extensively before you BASE jump it, and train in your
wingsuit extensively before you attempt any advanced maneuvers.
The ATC is intended for intermediate pilots who are seeking the handling
and maneuverability of a small suit design, with above average speed and
performance. The ATC flies well with “small” suits but has performance that
allows it to keep up with larger designs as well.
The ATC is capable of flying an endless variety of maneuvers at any
angle. Please note that the ATC is an intermediate wingsuit with backfly
inlets. What this means is that (like any suit with backfly inlets) the ATC will
maintain pressure in a back-to-earth configuration, even if you are not in
control of it. Respect the limits of your abilities and progress slowly. Seek
coaching and qualified instruction, and always maintain awareness of your
surroundings. It is your responsibility to avoid collisions with other wingsuit
pilots, parachutes, all air-traffic, and the planet Earth. Skydiving and BASE
jumping are extremely dangerous, and complacency kills.

Keep zippers close against MLW webbing. Handles completely exposed.
Zippers tight against MLW.

3D COMPRESSION INLET
ZIPPER BUNGEES
USE CARE AND FEEDING OF YOUR SQUIRREL
The 3D Compression Inlet is an advanced and effective innovation,
however it does require some care and maintenance. It is extremely
important that you do not abuse your inlets. Do not store your suit in a
tightly packed configuration. Do not store your suit folded tightly in hot
conditions. For instance, the worst thing that you could do would be to
leave it crammed into your stashbag in a hot car for a few hours - do
this, and your inlets will surely deform. In the case of inlet deformation,
massaging them into shape at or above room temperature will help
to re-form them.
The bungees that hold the zippers tight to the main lift webbing (MLW) of your harness must always
be connected. DO NOT jump your suit without the zipper bungees set tightly around your harness
MLW. Tying the bungees on the inside of the MLW usually results in the zippers being closer, and
the hole being smaller.
NOTE: If you think that the zipper system is not functioning well with your skydive harness (i.e. your
emergency handles are not always 100% accessible), please contact us immediately before your
next jump. You may need to modify the zippers so that the sliders stay locked in place, as per the
information at this URL: http://squirrel.ws/zipperstuff

LATERAL PASS-THROUGH
ARM FOAM OPTIONS
NUTSACK
The One-Zip system of the ATC features a “piano-hinge” style closure around the lateral webbing
of your skydiving harness. When you place your leg strap inside the suit, pass your harness lateral
through the piano-hinge system, and lace it up. Skip the tabs that are behind the lateral, attaching at
least one tab above the lateral to protect your zipper.
Your ATC is shipped with 5mm black foam, which is inserted in the arms. We recommend jumping
the suit using this foam option. The ATC may be jumped without this foam, but your leading edge will
appear less smooth, and be less efficient in flight.
Don’t overload your nutsack, it’s made for
your stuff-sack and not much heavier. Adding
a lot of heavy equipment or even too much
food or water will change your center of
gravity and could possibly affect your flight
in a negative way.

MYLAR
LEG WING ZIPPER PULLS
ARM AND LEG WING INTERNAL ZIPPERS
HOOK KNIFE
The mylar at your leading edge will become
creased and worn over time. Wrinkling and
creasing of this material is normal and will
not negatively affect your flight. You should,
however, take care to minimize the creasing
by packing your suit with care.
Always fasten your leg wing zipper pulls!
If you walk around with them dragging on
the ground, you will ruin them and it will be
your fault. If your suit is on, have the zipper
pulls connected. Do not drag them through
the dirt.
We recommend flying with them closed at
all times. You may experiment with opening
them to reduce internal pressure in the arm
and leg wings, but the ATC’s full performance
can only be experienced with zippers closed.
Make zipper-checks a part of your pre-flight
checklist.
Every suit comes standard with a Carbon
Aero Jack hook knife installed on the front of
the suit. Check to make sure that the hook
knife is loaded properly and that that snap
is secured.
When skydiving, please make sure that
the hook knife does not interfere with your
skydiving reserve handle and remove the
knife if necessary. If you have any questions,
please consult your rigger to ensure proper
operation of your emergency handles.

Palm rests against arm wing end cell.
Gripper provides structure.

HOLDING YOUR GRIPPER,
AND POSITIONING THE LEADING EDGE OF YOUR SUIT
Holding your grippers correctly is an important part of controlling your ATC. It is NOT necessary to
hold the gripper itself, tightly. Here are some examples of good and bad positions:
GOOD: Pilot’s fingers are all on the top surface (back side) of the gripper, resting against the arm wing end
cell. The grip is somewhat relaxed, with the thumb in front and the top of the gripper nestled gently in the palm
of your hand. Note that the gripper itself is not being held tightly.

7
BAD: All of these positions are very wrong. Please note how they deform the shape of the leading edge and
twist the zipper into a non-straight line. The leading edge is rolled forward, the sweep of the wing is changed,
and the bottom surface is not clean. All of these positions will result in decreased performance and control.
NOTE: It is NOT necessary to hold the grippers tightly in flight. You can comfortably fly your suit
from exit to landing with a very light touch on the grippers. It is better to NOT hold the grippers
than it is to hold them wrong, or to hold them too tightly.
SLEEPING AND BATHING YOUR SQUIRREL
Don’t smother your Squirrel! When it’s hibernating, it likes to breathe and relax in a cool, dry,
comfortable nest. Do not store your suit for long periods of time in a tightly folded or compressed
manner! Doing so will result in the deformation of your inlets. Always fully shade-dry your suit if it
becomes wet or damp. Gently rinse with non-chlorinated fresh water to clean, or if ever exposed to
salt water. Never use chemical detergents – Squirrels like it all natural, all the time!
Your suit can be hand washed in cold water, or machine washed
cold on a gentle cycle. Never tumble dry your suit. Hang dry in
the shade.
