Full-stall:
A full stall practically never occurs. It happens only as a result of serious neglect or
intentional action of the pilot. To avoid a full stall you have to be careful when flying at low
speeds until fully familiar with brake operation. The Colorado 2 recovers spontaneously in
the initial phase of stall, otherwise use standard procedures.
To recover from a full stall, smoothly release both brakes simultaneously until 90% of
leading edge reopens, then release brakes rapidly. The glider ends the full stall on its own
without surging forward violently.
WARNING!! If the brakes are released rapidly and asymmetrically, the glider may surge
almost 90° and suffer an extensive asymmetric collapse.
The danger of overcorrecting and overreacting exists during all extreme flight manoeuvres.
Any corrective action must be gentle and controlled. Proper training and experience is
required to gain a good feel for the glider! Always receive proper training.
Spin (or negative spin):
Normally it does not occur. You have to be careful when flying at low speeds until fully
familiar with brake operation. A negative spin can happen by pulling down the brake on
one side too fast or too hard. During a spin the canopy turns relatively fast around the
centre section of the canopy while the inner wing flies backwards (hence the term
negative).
There are two usual reasons for an unintentional spin:

One brake line is being pulled down too far and too fast (e.g. when inducing a spiral
dive in slow setting)

When flying at low speed the pilot pulls opposite brake too hard to try to compensate
for the engines torque.
To recover from an unintentional spin, the pulled down brake line should be immediately
released as soon as a spin is suspected. The canopy will accelerate and return to its
normal straight and stable flying position without losing too much height. If the spin is
allowed to develop for some time, the glider will surge far forward to one side resulting in a
dynamic asymmetric collapse or a cravat. Gently apply the brakes to the side that is
shooting forward to avoid the side/central collapse or the possibility of a cravat (one of the
tips becoming entangled in the lines).
WARNING!! If you are LOW and are in an unintentional spin, or if the canopy is caught in
a cravat - THROW YOUR RESERVE.
