Recovery
Let go fluently both brakes simultaneously until 90% of leading edge reopen, then
release brakes rapidly. The glider ends the full stall on its own without surging forward.
has very effective spiral dive. This allows rapid descent without stalling
.
Initiation
Weight-shift and pull the brake on one side gradually. Let the glider accelerate for two
turns and enjoy the growing speed and high G-force.
You can achieve sink rates up to 20 m/s.
Once you have entered the spiral you can control your descent rate and bank angle with
weight shift and brakes. We recommend lightly applying the outer brake to avoid
asymmetrical collapse on outer side of canopy.
Recovery
Weight-shift to a normal flying position and stop application of both brakes. The glider
stops spiral diving by itself in 360 degrees.
If you apply inner brake and decelerate the glider for two or three turns, big pendulum
effects can be avoided.
WARNING!!
If the brakes are released rapidly and asymmetrically, the glider may turn
through almost 90 degrees and suffer an extensive asymmetric collapse.
WARNING!!
Some gliders have a tendency to stay in the spiral when the sinkrate
exceeds around 15 m/s, depending on weight-shifting, wing loading and G-force. In fact
most gliders need a counter-input to end a turn. With weight-shifting to the normal sitting
position MUSE II will however come out of the spiral without pilot input. Practise
spiralling with caution and lesser sinkrates to get a feel for the gliders behaviour. A pilot
who is dehydrated or not accustomed to spiralling can lose consciousness in a steep
spiral dive!

Fly as far as possible from steep rises, to give yourself space to lose height.
Sink rate approximately 3-5 m/sec
Sink rate approximately 4-6 m/sec
This allows rapid descent without stalling. Sink rate, depending on pilot, 5-15 m/sec
Sink rate approximately 5-8 m/sec
- End the stall with sufficient time for the airflow to re-establish itself.
In principle, always fly in such a way that you do not need to lose height in a hurry.
The
is produced from the best materials (see Material Description). The glider
must be checked as a minimum, every year or after 100 flying hours. Do not step on the
lines. Although the lines were tested with „DHV-bend test“ they can be damaged if
stepped on whilst on a hard surface, or if they come into contact with sharp objects.
If this happends contact your dealer for replacement lines. The lines must be checked
after every 50 hours flying time and whenever the flight behaviour changes. Consult your
dealer or MAC ltd. Tears in the canopy must be professionally sewn. Adhesive patches
are only adequate for very minor damage. The glider must always be kept cool and dry. If
possible it should be stored lightly folded in a well-ventilated place. Protect the glider
from dampness and sunlight. Exposure to UV degrades the fabric. A damp or wet
canopy must be air-dried in a shady place. Do not expose the glider to temperatures of
greater than 50 degrees C, as this can cause softening and shrinking of the attachment
tapes. Clean the canopy only with warm water or a dilute soap solution. Do not use
solvents.
