How does the C-steering work?
The so-called HAC handles (Height Adjustable C-Handles) are moun-
ted on the C-risers. These permit a more efficient pitch control, usual-
ly only possible on two-liners. The effort required to apply them is so
minimal, that even after a long flight they never cause fatigue. In ac-
celerated flight, the HAC handles can be used to increase the angle of
attack more quickly and sensitively than would be possible by relea-
sing the speed bar. Additionally, asymmetrical corrections are possib-
le, e.g. for a change of direction. In the end, the C-steering means it is
possible to fly faster, more efficiently and in a more relaxed manner. At
trim speed, if the HAC handles are pulled down about 20 cm, a stall
occurs, but the pilot will know this in advance through pulsating feed-
back on the handles. Well before the stall, performance is noticeably
reduced. It is therefore not advisable to permanently slow down the
MENTOR 7 Light below trim speed.
Speed system geometrical data
If the entire speed range is utilised, the A-risers will be shortened by
21.5 cm, the B-risers by 14.3 cm and the B3-riser by 10.7 cm (sizes
XS and S). In size M, the A-risers will be shortened by 23.5 cm, the
B-riser by 15.7 cm and the B3-riser by 11.7 cm.
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 7 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.
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!

Instructions for adjusting the height of the HAC-Handles:
remove both caps from the carbon tube, loosen the screw
connection, position the HAC handle at the desired height,
close the screw connection and replace the caps.
