Use the supplied bungie loop to go through the key ring on the turnbuckle
and up to the bolts on the roll bar. See photos in this manual for details. This
provides a secure system to insure that the turnbuckle will not turn loose in flight.
3.15
Attach your motor unit
. Use the Universal Motor Clamping System on the
GRAZ
hopper
to connect the bottom and upper frame tubes. Also, use the supplied
doublesided Velcro to attach the motor unit to the GRAZ
hopper
wheel axels and as a
safety backup for the top motor clamp.
ATTENTION
:
With some motor units, the Universal Motor Clamping System may need
to be modified to fit properly. Be sure that your Universal Motor Clamping System is
securely holding the fame of your particular motor. If you have any doubts, do not
hesitate to contact your product dealer or Airparamo LLC directly.
3.16
Do a thorough
flight check
of the GRAZ
hopper
, motor and attachment points.
WARNING
:
Always turn off the master switch on any PPG motor when conducting a
preflight check.
3.17
Warm up the motor.
WARNING
:
Always loudly announce “CLEAR PROP” before starting any PPG motor.
WARNING
:
Do not attempt to start a PPG motor without instruction from a qualified
instructor. There are dozens of instances of pilots and spectators who have been
severely injured by coming in contact with a spinning propeller.
3.18
Hang test
the GRAZ
hopper
. This helps to
test your harness and hang point
positions. To do this properly, set up a
rigging arrangement where you can safely
and securely hang the trike while you sit
in it. It helps to have an observer,
especially with a camera, to report or
record the correct prop angles (between 2
to 5 degrees downwards while hanging in
the air) and seating positions.
WARNING
:
Do not attempt to fly a
GRAZ
hopper
trike that has not been
properly hang tested. It could be out of
balance, resulting in an undesirable or
dangerous flight attitude.
WARNING
:
We do not recommend to run the motor on the trike while it is being
hang tested. The torque and thrust forces could create an emergency situation very
quickly. If you do want to run up the motor in the hang test rig, you do so at your own
risk.
3.19
Check all nuts and bolts are tight.
3.20
Test drive
the trike for a few minutes.
WARNING
:
Be careful to not turn too sharply with any speed. This could initiate a
rollover.
ATTENTION
:
Rough terrain, thorns, nails, sharp twigs, or other debris can easily
puncture and damage the tires.

Set-Up & Breakdown
Once the trike is fully assembled, set up and break down can be accomplished in under 5
minutes. For the set up, refer to sections 3.7, 3.9, 3.14 to 3.17, and 3.19 of this Owners
Manual. For the break down, refer to sections 3.15, 3.14, 3.9, and 3.7 of this Owners
Manual and detach and loosen parts.

Take-Off, Flight, & Landing
WARNING
:
Do not attempt to operate or fly a GRAZ
hopper
trike without qualified flight
instruction. The PPG trike is quite different from other types of PPG or PG flight and the
subtleties of learning to fly a PPG trike can be unforgiving and dangerous. There are dozens
