The NAJA is most efficient when cruising if the trimmers are slightly open. A trimmer
can be closed again as much as is needed to counter the torque effect of the motor. If
there are very turbulent conditions, the trimmers should not be used, since the canopy
stability decreases because of the lower angle of attack.
The NAJA has very direct and agile turn behaviour without any negative tendency,
which allows very dynamic flying.
The NAJA has not been trimmed for flat turns like a thermalling glider, so it makes little
difference whether a turn is flown with or against the counter-torque of the motor.
Tip
Be careful when flying in your own wake.
Be careful when turning near the ground (sink during turns).
Although there is less susceptibility to collapse with a motor running than in free flight
because of the higher surface loading and the increased angle of attack, the trimmers
should always be closed in strong turbulence.
When flying in turbulence, apply the brakes slightly (about 20%) and try to keep the
canopy above you by actively working the brakes. This helps you to stop the wing tips
collapsing. If a wing tip should nevertheless collapse, it is important to maintain your
direction and, if necessary, to steer away from any obstacles. You should not ‘pump’ the
wing to make it reopen more quickly until your flight is stable again. This must be done
somewhat more energetically because of the generally higher wing-loading with a
paramotor wing.
When flying in strong thermals, release the brakes and reduce the motor’s revs per
minute so that you do not go into a dynamic stall. However, when you are leaving a
thermal, brake the canopy well and increase the rpm so as to avoid pitching forward and
a possible frontal tuck.
Tip:
If you experience a collapse, counter-brake the canopy until you stabilise the glider
in level flight. Too little counter-brake is better than too much.
You should not brake the NAJA too strongly before landing because of the
comparatively high surface-loading. We recommend that you completely release the
brakes in the final approach and then, when you are approx. 1-2 m above the ground,
you gradually apply them until they are completely on (flare).
Please ensure that the length of the brake lines was set to the optimum level for your
motor before the first flight to allow sufficient braking distance for landing.
You have the option of using the motor to assist the landing approach.
The height and speed can be controlled using the brakes and the rpm until you touch
the ground.
Caution – accident risk.
When you are flying near the ground, always maintain enough speed (well above the
stall limit).
