Take-Off

As the A-tabs are positioned further back we recommend pulling more on the A-risers as used
on conventional gliders. The glider stays stable and rises constantly using forward or reverse
launch techniques. Allow the glider to stabilize overhead and run positively forward, checking
the canopy is fully inflated and clear of any knots or tangles. Reverse launching is
recommended in stronger winds.
The glider has split A-Risers. For launching, you can take just the inner A-line risers – this avoids
a horse-shoe style during take-off – especially in nil or back wind.

Turning Flight

Your will notice the agile handling from the first flight. The PURE3 is easy to turn at any bank
angle, from flat through to steeply banked turns.
Brake pressure is progressive, which enables the pilot to feel the wing and helps prevent
unintentional stalling.
In turbulent air the PURE3 absorbs turbulence very effectively which improves pilot comfort in
flight.
The available brake travel before stalling the wing depends on the size and the loading. For the
PURE3 M it is a minimum of 45cm. Those numbers are just a rough indication. (The publication
of the brake travel is claimed by the EN 926-2.)
It would be dangerous to use the brake travel according to those numbers, because it is not
practicable to measure the brake travel during flight, and in turbulences the stall might occur
with less brake travel.
Brake-Shifting
The webbing attachment for the brake-line pulley is intentionally long making it possible to
move the brake handle either to the inside or outside of the PURE3r.
For example: If the glider turns flat, make a steeper or faster turn by moving the inside hand
towards the centre of wing. The glider then speeds up in the turn and the angle of bank
becomes steeper. When doing the opposite – moving the arms away from the body - the glider
