RISERS
Speed system:
The PitBull RX is equipped with a speed bar operated speed-system which returns
automatically to the normal position when released. The speed system affects the A, A1, 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 17,5 cm. The A1 risers are shortened by up to a max of
14,0 cm. The B risers by up to a max. of 12,5 cm. The C risers are shortened by up to a max.
of 5,0 cm, and the D risers are released for 2,5 cm. 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 PitBull RX has a wide in flight speed range due to the range of different trimmer
settings. The trimmers have a deceleration range of 2.0cm and 7cm of acceleration. On
the faster setting (trimmers fully open and extended) the PitBull RX’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 PitBull RX 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 double white line) is the position where the
risers are level. This is the most useful configuration for navigation and for precision
ground tasks. The PitBull RX 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 PitBull RX, 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 PitBull RX is fully accelerated with
trimmers all the way open and speed bar pushed all the way out. Maneuver the
PitBull RX by pulling on the wing tip steering lines only.
