3.15 Do a thorough flight check of the GRAZhopper, motor and attach points.
WARNING:
Always turn off the master switch on any PPG motor when conducting a
preflight check.
3.16 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.
3.17 Hang test the GRAZhopper. 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
GRAZhopper trike that has not been
properly hang tested. It could be out of
balance, resulting in an undesirable or
dangerous flight attitude.
WARNING:
Be extremely cautious to run the motor on the trike while it is being hang
tested. If you do want to run up the motor in the hang test rig, be sure to do this in a
secure, sturdy hang test rig and with the assistance of an experienced instructor who
is thoroughly familiar with motor runups in a hang tester.
3.18 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:
The GRAZhopper has no brakes. When you need to slow down ground
speed, use your feet to bring the GRAZhopper to a halt.
ATTENTION:
The original bearings in the Rolleeze wheels are designed for walking
pace speeds only. If you go faster than a walking pace for more than a few seconds,
the bearings will heat up and potentially melt the housing.
NOTE:
A bearing upgrade is available to replace all the original nylon bearings to all
steel bearings. Please contact your product dealer or Airparamo LLC for more
information on this or other upgrades.
4. 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 3.6, 3.12, 3.13, 3.14, and 3.15 of this Owners
Manual. For the break down, refer to sections 3.14, 3.13, 3.12, and 3.6 of this Owners
Manual and detach and loosen parts.
5. Take-Off, Flight, & Landing
WARNING:
Do not attempt to operate or fly a GRAZhopper 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
of examples of PG and PPG pilots and complete newbees that have attempted to self-train
on PPG trikes and ended up severely damaging themselves and their gear. Consider that the
flight training is cheap compared to a broken arm or torn up wing and cage. Contact your
PPG flight instructor or Airparamo LLC on recommendations for instruction.
