Take off
When pilot carries the paramotor,
the struts point towards the ground, not limiting the pilot in his
movements. Before start, the prop thrust line is pitched slightly
downwards, allowing the pilot’s body to tilt naturally when
starting to run. At the moment of starting the take-off run the prop
thrust line is still slightly pitched downwards, allowing the
pilot’s body to keep a natural attitude. After the take-off, the
sliding grommets on the struts move forward due to the tension of
leg straps – and the pantograph starts to optimise the direction
of thrust of the power unit. By changing the position of his legs
the pilot changes the position of sliding grommets and thus vectors
the thrust of the power unit. The system works automatically,
allowing the pilot to devote his attention fully to controlling the
flight. The Praying Mantis is equipped with a double bar for
controlling both the pilot’s attitude and the flight. After the
start, the pilot remains in a vertical position, allowing him to run
in case of a bouncy take-off or in a forced landing if a loss of
power occurs. Upon reaching a safe altitude, the pilot puts his heel
into the bar No.1. By actuating the bar, the pilot’s body tilts
back to the low-drag reclining position (this movement, however,
does not change the angle of incidence of the paraglider wing). The
position gets fixed automatically, as the sliding grommets move on
struts until they lock into the end grooves. By moving the heel to
bar No. 2 (it offers itself to the pilot once he takes the reclining
position), and pushing on it (speed system), it is possible to
increase the speed of the MPG by reduction of the paraglider wing
angle of incidence. A reverse process is used if pilot needs to
return to upright position. Bar No.2 is released and bar No.1
actuated. This action loosens the sliding grommets’ locks,
permitting their release and their movement back to the start and
landing position. Thus the pilot is ready for the landing manoeuvre.
Note!!!
Due to the tilt of the pilot and transition of the main snap-ring
of the suspension there also changes the suspension height and
consequently also the position of the control handles. That is
why the pilot must pay attention to the changed travel of the
control handles during their operation, so as not to stall the
wing unwillingly.
Landing
During the landing manoeuvre the pilot’s does the following:
1. If he does not stand in the speed bar No.2 and the sliding grommets on
struts are secured in their terminal position:
a) he steps off the bar No.1. (in emergency it is possible to land
relatively safely even with sliding grommets’ secured in their terminal
position on the struts, but for correct functioning of the harness
it is desirable for the above stated manoeuvre to be performed – step
off the bar No.1 and continue in compliance with point b).
b) he releases the tension in sliding grommets’ locks, releases them
and allows them to return to their position for start and landing
c) he releases and leaves bar No.1, frees his legs from the harness
seat and gets ready for the touch-down and final landing run.
2. If the pilot stands in the speed bar No.2, he must leave the bar
and proceed in compliance with points a, b, c
