Due to typical PPG feature - considerable vertical distance between wing
chord and thrust axis - the range of safe power operation is closely related to
your skills and equipment.
Power-unit induced oscillations
Certain configurations of engine weight, output and propeller diameter can
cause serious oscillations, during which the pilot is being lifted to one side by
the torque effect, swings down due to his weight, then is lifted again and so
on.
To avoid this you can:
+ change the throttle setting and/or
+ adjust the cross bracing to counteract the torque, if there is one present
and/or
+ use the TEA, pulling down the knot through the tube, simultaneously
blocking it in the slit and/or
+
shift yourself to the other side of the harness and/or
+
change the trimmer setting.
+
while on the ground, attach the risers asymmetrically, using optional
carabiner loops.
The best method is to fasten opposite cross-bracing or apply some weight-
shift. Such oscillations usually occur at full power - the greater the engine
output and propeller diameter, the bigger the swings. In addition there are
often too late or wrong pilot reactions, increasing the problem instead of
solving it. In this case the safest way to deal with this question is to close the
throttle and release the brakes.
3.4 LEVEL FLIGHT
Once you have gained safe height after take-off and wish to
go for a route, you can turn onto right direction, fully open
the trimmers and let off the brakes. If the conditions are
turbulent, it can look foolhardy, but this is the essential
feature of the reflex profile - the faster
you fly, the safer your Snake XX is.
That's why it's really possible to
release the brakes and enjoy your
flight.
CAUTION: Some pilots with previous free-flying
experience may have a well-grounded habit of
keeping the brakes slightly applied at all times. Such
