* All control inputs should be smooth and progressive.

* Don’t attempt to take off if the canopy isn’t roughly level overhead.

Dangerous oscillations may result if you apply full power with the canopy off to one side.

* Keep your undercarriage down until you are definitely flying!

* The faster the trim setting, the more brake the glider will need to get off the ground.

Speed systems may cause problems when clipping in. Don’t get your lines crossed!

The Climb Out

Once off the ground and flying safely, continue into wind using the brakes to achieve the desired
climb rate. Don’t attempt to climb at too steep an angle. Attempting to use too much brake to force a
higher climb rate will only degrade the climb by creating extra drag and with the addition of lots of
thrust this could result in a stall or a spin.

Under power the Bolero 4 behaves more like a powered fixed wing airplane than a paraglider, and it
helps to think of it as such.

Provided there are no obstacles in your path, it is often safer to fly level with the ground after take-
off gaining more speed before converting it into height using the brakes and then easing off into the
climb out.

The other reasons for not climbing out too steeply are the risks involved when having engine failure,
i.e. a stall and diving recovery.

Although the Bolero 4 will not sit back behind you a slow forward speed and high angle of attack is
still likely to put you into a near stalled attitude if your power source suddenly fails. In this situation
you should always be able to set up a reasonable approach, so maintain sufficient airspeed at all
times, and keep your angle of attack under control at low altitude.

Depending on the geometry of the set-up of your power unit, the propeller’s torque effect may make
itself felt as you leave theground. Expect it to turn you and, if necessary, steer against it in order to
maintain your direction. However, when countering the torque effect during a steep climb on slower
trim settings under a lot of power, care must be taken to avoid the risk of stalling.

Because of the large vertical distance between the thrust line of the prop and the wing common to all
paramotors, the extent of the power management required is critically dependent on your set up and
flying ability.

Power induced Oscillations

Certain combinations of weight, power, and propeller size can cause oscillation where the torque and
gyro effects lift the pilot to one side; you then drop back only to swing up again. To counter this you
can do one or more of the following:

* Alter the throttle setting

* Adjust the torque strap if fitted

* Shift your weight in the harness
