RISERS
B and C-risers and changes the angle of attack. In normal flight all risers have an overall
length of 49 cm without quick links. When the speed bar is pushed out with your feet,
the A-risers are shortened by up to a maximum of 20 cm. The A1 risers are shortened
by up to a max of 18,5 cm. The B risers by up to a max. of 17 cm. The C risers by up to
a max. of 9 cm, and the D risers retain their original length. To use the speed system
you have to attach the brummel hooks found on the front of the risers and connect them
to the brummel hooks found on the speed bar. If your paramotor harness did not come
with a stirrrup style speed bar contact your local dealer to purchase one. More detailed
instructions can be found in the chapter below called Setting up the Controls.
Trimmers:
The Chronos has a wide in flight speed range due to the range of different trimmer
settings. The trimmers have a deceleration range of 3.5cm and 7cm of acceleration. On
the faster setting (trimmers fully open and extended) the Chronos’s speed increases.
The wing is less sensitive to turbulence and the stability improves. On slower trimmer
settings (neutral or trimmers pulled all the way down), sink rate improves and the brake
pressure becomes lighter. You will feel that the wing is more sensitive flying through
bumpy air with trimmers pulled all the way in.
To help you identify the neutral
position of each trimmer, look for the white stitching. It is important to check and set
the trimmers in the same position for each riser before take-off and in flight to avoid
unwanted turns.
The speed of the Chronos with closed trimmers (trimmers pulled all the way down) is
around 39-43km/h with a relatively low effort of the engine. With additional brake
pressure the cruising speed is around 34-37 km/h. This will give you the best sink rate
and requires the least amount of thrust from your engine for level flight. This position is
ideal for economy navigation tasks.
The neutral trimmer position (marked with a white line) is the position where the risers
are level. This is the most useful configuration for navigation and for precision ground
tasks. The Chronos still turns very well and restores plenty of energy flying around 44-
47 km/h. It requires a little more RPM from your engine compared to the closed trimmer
position. It is recommended to use this configuration when using the speed system!
With the trimmers fully open the speed is around 49-52 km/h. You will notice the main
brakes will become harder to pull. This is normal. With fully released trimmers the
canopy is in its semi reflex mode and becomes more solid. To fly at maximum speed
with your chronos, fully release trimmers and push the speed bar out all the way by
pushing on it with your feet. The maximum speed is around 60-63km/h. Higher fuel
consumption will result in this configuration.
WARNING! Do not use the brakes when the Chronos is fully accelerated with
trimmers all the way open and speed bar pushed all the way out.
Maneuver the Chronos by pulling on the torque compensator line in replace of the
brakes.
