Speedbrake Riser Function
The MENTOR 6 Light is fitted
with the Speedbrake Riser Func-
tion as standard. This is a tie strap
which allows the pilot to »decele-
rate« the wing. If the pilot pulls the
C-riser back and downwards in a
radius (with the maillon as the centre of
rotation), the B-riser is also reduced in
length. The result is that the wing flies
slower and without creases. More
specific information can be
found here:
Important:
If the Speed-
brake is pulled too much or
too suddenly when the wing
is already pitched back there
is the risk of stall. Please practise
using the Speedbrake Riser slowly, incrementally
and in calm conditions.
Speed system geometrical data
If the entire speed range is utilised, the
A-risers will be shortened by approximately
18 cm, the A2-risers will be shortened
by approximately 15 cm and the B-riser
by about 13 cm (sizes XS, S, M and L). XXS: the A-risers will be
shortened by 14 cm, the A2-risers by 12 cm and the B-riser by 10 cm.
Turning
Turning a wing is the combination of inner brake, outer brake and
weight-shift. The key is the correct dose of each element. One of the
features of the MENTOR 6 Light is its sensitive handling. Small brake
inputs are sufficient to fly precise turns.
Some of the required techniques can be practised during ground hand-
ling, for example, by attempting to keep the wing flying above your
head without looking at it. This exercise is also useful for successful
forward launches.
Accelerated flight
Fitting the speed system
The majority of harnesses are fitted with two pulleys per side. Some
(lightweight) harnesses instead have two simple rings or loops. The
two speed bar cords are pulled from top to bottom through both
pulleys/rings and fitted to the foot bar.
The correct length adjustment is important. If it is too short, there is
the danger that the wing is constantly accelerated, which should be
avoided at all costs. If the cords are too short there is the risk that the
speed bar is unreachable.
If the cords are set too long, it is not possible to accelerate the wing to
its maximum speed.
We recommend setting the cords a little too long when first fitting the
speed system, so that the free play can be judged during flight. Then
the slack can be taken up if necessary. Brummel hooks with three
holes assist with the simple adjustment of the cord length.
Using the speed system
Before take off or on connecting the risers to the harness, the Brummel
hooks on the speed system must to attached to those on the harness.
Please make it part of your pre-flight routine to connect the speed system
– it is important for your safety.
The MENTOR 6 Light is fitted with a very effective and smooth-run-
ning speed system. Up to the maximum speed, the glide performance
remains very high. Pitch correction, i.e. active flying, in accelerated
flight should not be performed through the brakes, but using the speed
system. Therefore if the wing pitches forward, the pilot should not
brake, but reduce the acceleration.
In accelerated flight, steering should be performed either by weight-shift
or through asymmetrical speed bar use (by increasing the acceleration
on the left side, the wing will turn right).
Please note: using
the brakes during
accelerated flight is
not only detrimental
to performance,
but (in comparison
to non-accelerated
flight) it increased
to likelihood of
collapses!
!
The NOVA Speed-
brake Riser is the first
three-liner riser which
permits the glider to
be accelerated as
well as decelerated. It
brings an end to pul-
ling the C-lines, which
killed performance.
