Welcome to
the FLY PRODUCTS world! We are one of the
oldest builder of Powered Paragliders (PPGÍs) in the world.
We at FLY PRODUCTS put all of our long experience into our products for
to give you the state-of-the-art in all of our products.
1.1
Safety First!
Powered ParaGliding (PPG) is the newest form of aviation. ItÍs also
the most exciting, least expensive, safest, most accessible form of aviation
EVER! However, it is still aviation, and it brings with it all the
inherent potential dangers of any form of aviation. People can,
and do, get hurt and even killed in any form of aviation, including PPG.
For that reason it is imperative that all PPG pilots receive proper training
from certified instructors, offer PPG the respect all aviation deserves,
respect weather and conditions, and realize that in the end, it is the
pilot himself that is responsible for his own safety and the safety of
fellow pilots and bystanders. Enjoy PPGing to the fullest, and welcome
to the sport!
Please
read and be sure you thoroughly understand this OperatorÍs Manual before
starting or flying your POWER JET. It contains information critical
to the safe operation of the Powered Paraglider.
Powered
Paragliding is an extremely demanding sport that requires exceptional
levels of attention, judgement, maturity, self-discipline, and attention
to detail. It is unlikely that you will be able to participate in
it safely unless you make a conscious and continual commitment to your
own safety.
Due
to the inherent risks in flying this or any PPG, no warranty of any kind
can be made against accidents, bodily injury, equipment failure, and/or
death.
This
PPG is not covered by product liability insurance. Do not start
it or fly it unless you are willing to assume all risks inherent in the
sport of Powered Paragliding and all responsibility for any property damage,
injury, or death which may result from the use of this product.
1.2

|
Frame
assembly and disassembly on the PJ125 is very fast and easy.
The
frame consists of four parts, and they are held together by the
support rods.
To
init the assembling, Place the PJ125Ís central frame (the engine
unit) on a flat surface.
|
For
an easy and correct assembly proceed in the following order:

Fig.
5 - Support rods
|
Step
n. 1. - Support rods.
Plug
all six cage support rods into their bushings
on the central frame (engine),
take attention to put longest on the top.
|

Fig. 6 - Upper mount
|
Step
n. 2 - Assembling upper frames
Make
sure that the cage netting is in front of the cage support rods
as shows in the picts.
Place the upper frame quartes onto the upper support rods and
rotate the frames until plug in the inserts in the related holes.
Lock
the velcro strap as shown.
|

|
Step
n. 5 and 6 - Assembling lower frames
Place
the lower frames onto the central engine unit frame plugging the
inserts in the related holes.
Lock
the lower velcro straps.
|
NOTE!
The cage support rods must be completely seated into their bushings in
the frame, and into their bushings in the cage,
if they are not seated completely into their bushings, you will be unable
to fasten the netting into place in the next step.
|
|
Step
n. 7 - Fasten the net.
Attach the netting tension strings as shown in the figures, simply
passing the string-hook into the string loop, pull
it tight, and then hook it back onto the string loop.

completes the assembly of the prop cage.
|
DISTANCE
BARS: These distance bars are extremely easy to mount and dismount
since they slide easily into the central frame. The end of the distance
bars are made of a square aluminum profile that does not allow them
to rotate. Due to the compression of the harness, the distance bars
can not slide out of their fittings during flight.
|
|

Fig.
12 Distance
bar sistem.
|
ANTITORQUE
SISTEM
The
distance bars are designed to favor the sliding of front harness
webbing in a way that the pilot finds the proper angle with the
paraglider. With this system the discharge of the propeller torque
onto the risers is avoided, which usually gives the the tendency
to turn one direction that in the case of the rotation of the Solo
210 engine the tendency is to turn right.
|
|
LATERAL
WIDENING OF DISTANCE BARS.
The distance bars allow a lateral movement which is useful for
the pilot to enter easily into the harness.
|
Next,
attach the bottom of the harness, then work toward the top.
Attach the bottom ground handling straps as shown in Fig.
13.
Do this for the left and right sides. Leave these straps at their
loosest setting for now, weÍll adjust them later.
|

|
Finally,
fasten two top mounting straps around the top tube of the frame
(Fig. 15).
Fasten these belts securely as in Fig.
14,
or, in case of the model with the eyelet bolts, hook the two triangular
carabiners to the eyelets.
This
completes the harness mounting. Inspect your work to ensure
that all is OK.
|
2.4
Prop Mounting
NOTE: Here is some terminology
weÍll use in this section.
The
ñfrontî is the direction the pilot faces while flying, the ñrearî is the
opposite direction.
The ñfrontî of the prop can be identified by the thick side of the prop
blades.
The ñrearî side of the prop can be identified by the thin side of the
prop blades as the upper blade section shown in fig. 9.
The ñrear prop flangeî is the one that is most rearward when the prop
is mounted.
The ñfront prop flangeî is the one that is mounted on the reduction drive.
|

Fig.
16 Upper
view of a propeller section.
|
Mounting
the prop is quick and easy.
Place the rear prop flange on the rear side of the prop.
Insert the four (4) prop bolts through the rear prop flange and
prop.
Place the black rubber friction washer over the prop bolts on
the front side of the prop as shown in Fig. 16.
Now mate the prop/rear flange/bolt assembly to the front prop
flange that is on the reduction drive.
Place nylon-insert lock nuts on the bolts, and tighten them evenly.
The correct torque to use is 50-inch lbs. MAX.
A more practical ñfield methodî of torquing is to tighten the
bolts snuggly
and evenly, but not enough to begin to crush the wood of the prop.
The
red arrow in picture, indicate the sense of propeller rotation.
|
2.5
Spark Plug
Set
the spark plug gap to 0.025î (0.635mm). Install the spark
plug and torque to specifications (120-inch lbs. or 10 ft-lbs.).
2.6
Assembly Inspection
It is critical to fully inspect the assembly of the POWER JET and find
and remedy any problem areas before proceeding. The inspection should
contain, at a minimum, the following items:
- Review
each assembly step above
- Examine
all nuts, bolts, and fasteners for security
- Check
the harness for correct mounting, that all straps are secure, that there
are no twists on any straps
- Examine
prop cage for correct assembly, that it is strong, the netting is tight
and on the correct side
- Check
that nothing can get in the prop. The prop should clear the cage
by at least 2.5 inches (4 fingers) at all points
- Check
the fuel tank and fuel delivery system
- Check
for correct mounting of prop, and correct torque of prop bolts
3.0 PREPARING
FOR YOUR FIRST FLIGHT
back

3.1ææ
Fuel and Oil
FLY PRODUCTS recommends the use of a premium
unleaded automotive gasoline of 92 octane or higher, and the use of
premium synthetic 2-cycle oil. Mix fresh gas and oil before each
flying session. Store your fuel/oil mixture in an approved, sealed
container. Dispose of fuel/oil mixture that is older than 72 hours.
The
recommended fuel/oil ratio is 50:1. Be sure to thoroughly agitate
the mixture to completely dissolve the oil. Use only fresh fuel
and oil, and use clean containers, funnels, hoses, etc.
To
fill the fuel tank, remove the fuel tank by unscrewing the fuel tank
cap . Take care not to get dirt, dust, etc. onto the fuel pickup.
It
is recommended that the fuel be poured into the tank using a straining-type
of funnel. Fill the tank with the desired amount of fuel..
Tighten the fuel cap securely.
NOTE:
Wipe up any spilled fuel immediately, as the fuel/oil mixture is highly
flammable, and an in-flight fire would be catastrophic. Also,
the oil will leave a residue, which will attract and retain dust and
dirt.
WARNING!
Use common sense when refueling. Do not refuel a hot or running
engine, do not smoke or allow on-lookers to smoke while refueling.
Do not refuel near heat or open flame.
3.2
Before Starting the Engine
Before starting the engine on the ground, ensure that the unit is in
an area free from dirt, rocks, dust, etc. that could be sucked up and
thrown around by the propeller.
Check
assembly of the unit, and especially check any and all nuts, bolts,
and screws, that could be loose. Also check all parts of the prop
cage for looseness. The prop produces a significant amount of
thrust, and can suck things into it from a surprising distance.
WARNING!
Ensure that no bystanders or onlookers are close by when starting the
motor. The most dangerous place to stand is in the plane of the
propeller. This is where dust, dirt, rocks, nuts, bolts, etc.
will be thrown if they are picked up by the prop.
At
full RPM, the prop tips are moving in excess of 370mph, and pushing
the air rearward at over 62mph. This amount of force can pick
up anything loose in the area and throw it around like a bullet.
Not only can it severely injure you or bystanders, even small items
like dirt can inflict significant damage to the prop.
3.3
Starting and Stopping Engine
| |
3.3.1
Stopping the Engine
Since itÍs important to know how to stop the engine once
itÍs started, letÍs cover ñStopping the Engineî first.
To stop the engine, simply depress the ñSTOPî button (fig. 10
- "A" ) and hold it until the engine comes to a complete
stop.
 |

- STOP button
B
- START button
C
- Throttle lever
D
- Throttle lever hold to half power
E
- Velcro strap
|
| Fig.
17 - The handgrip |
|
It
is important to be aware of some other engine stopping techniques,
should the stop switch not function correctly.
The stop switch may not function correctly due to
-
faulty
switch,
-
broken
or frayed wires,
-
bad
connections to any part of the stop switch circuitry.
For
this reason, the following emergency stop procedures are available:
To
stop the engine if the stop switch doesnÍt function correctly,
you can
-
Place
your hand over the airbox intake hole
-
Place
the carburetor choke in the ñONî position
-
Squeeze
the fuel line (requires an aggressive squeeze, and takes about
two minutes to stop the motor)
3.3.2
Starting the Engine
Now
that weÍve covered stopping the motor, letÍs get to the fun part!
There
are three different positions that can be used to start the engine.
These positions are:
-
Standing
in front of the unit, holding the unit on the ground
-
Strapped
into the unit, standing on the ground
-
In
Flight
WeÍll
cover each of these starting options in turn.
If
the engine is cold it's very important to fill the fuel pipes
squeezing the apposite fuel pump placed near the fuel tank.
-
Standing
in front of the unit, holding the unit on the ground
WARNING!
The method of holding the throttle handle is important in
this position. Hold the throttle handle such that you
can easily reach the stop button, but not so that you can
inadvertently squeeze the throttle. A common accident
can happen where you hold the throttle in the same hand that
you hold the motor unit, and if you squeeze the throttle a
little, the thrust of the machine will push the throttle onto
your hand, causing you to squeeze the throttle even more.
Make sure that you CANNOT inadvertently squeeze the throttle
handle when starting in this position.
- Stand in front of the unit, and place your left hand
on the top of the central frame tube. Hold the throttle
in your left hand also, noting the warning
above. Grasp the pull-starter cord with your right
hand.
- Gently pull the pull-starter cord until you feel the
engineÍs compression. Allow the pull-starter cord
to rewind into the motor. Rapidly and sharply pull the
starter cord. The engine should start after one
or two pulls.
- Gently pull the pull-starter cord until you feel the
engineÍs compression. Allow the pull-starter cord
to rewind into the motor. Rapidly and sharply pull the
cord. The engine should start after one or two pulls.
-
Strapped
into the unit, standing on the ground
In this position is possible to leave the throttle hanging
to the right side of the harness, grasp the pull-starter cord
with both hands and proceed like to the position above.
-
In-Flight
For information on this starting position, refer to the
ñIn-Flight Startingî section under ñFlying Your POWER JETî.
CAUTION!
Do not allow the starter-rope to snap back into place after
youÍve started the motor. Gently place it back into place.
3.3.3
Choking the engine
If
the engine hasnÍt been run in a few hours and is no longer warm
to the touch, use of the choke will be needed. The choking
procedure is as follows:
-
Move
the choke lever to the ñONî position.
-
Pull
the starter rope until the engine starts.
-
Move
the choke lever to the ñOFFî position.
-
Allow
the engine to stabilize a few seconds before applying throttle.
The
choke lever and itÍs ñONî and ñOFFî position can be seen in Fig.
11.

3.4
Carburetor Adjusting
Our
carburetor is provided with a starter for the very first starting (cold
starting) Flip up switcher A in position 2 for starting, in position
1 for functioning.
You can set the carburetion at the desired revs. by the long black downward
screw C. By turning it anticlockwise you rich the mixture, while the
opposite you lean it.
The basic setting is between 1 and 2.5 turns from the shut position.
The C screw must be turned very gently, always verifying the cleanliness
of the "passage" (the point where the nozzle of the idle enters the
nozzle of the full, at about half revs.) in revving up. If the engine
pops, you tighten it, if it abates you loosen it.
The D screw sets the revs. at idle, by opening the butterfly valve.

The POWER
JET carburetor has two adjustments, detailed in Fig.
11.
Carburetor
adjusting proceeds as follows: Warm the engine by allowing it to idle
for at least 5 minutes. Adjust the idle mixture C for the fastest
idle possible. Once attained, adjust D for the slowest smooth
and stable idle possible.
Often,
after making a few adjustments to the carburetor, it is necessary to
ñstart overî, and go back to the original factory settings.
The original factory settings for the carburetor are:
To
restore the adjustments to the factory settings, GENTLY turn the screws
CW until they hit their stops, and then back them out (CCW) the number
of turns described above.
3.5
Engine Break-In
Break-in of the POWER JETÍs Top 80 Engine is required before the first
flight. Proper break-in will provide you with a better running
engine, it will also provide for considerably longer engine life. During
the break-in, gently change RPM from idle to full-throttle and back.
Do not rapidly change RPM, as this causes unnecessary wear and tear
on the clutch. The procedure is as follows:
-
Run
the engine, varying the RPM, for 2 minutes.
-
Stop
the engine and let it cool for 2 minutes. Check for loose bolts,
etc. during this time.
-
Run
the engine, varying the RPM, for 5 minutes.
-
Stop
the engine and let it cool for 5 minutes. Check for loose bolts,
etc. during this time.
-
Run
the engine, varying the RPM, for 10 minutes.
-
Stop
the engine and let it cool for 5 minutes. Check for loose bolts,
etc. during this time.
-
Continue
10 minutes of running, 5 minutes of cooling until 30 minutes of run
time is achieved.
At
this point, you can fly the POWER JET, however avoid long durations
of full power, and vary the throttle setting often.
For heavier pilots that require more power to fly, it is recommended
that 1 hour of non-flying break-in be completed before flying.
Break-in is complete after 10 liters of fuel have been run through the
engine.
CAUTION!
Be wary of overheating during the break-in process. It will show
itself as a loss of power.
Should this occur, reduce power and land as soon, as is practicable.
Allow the engine to cool.
Check to ensure the carburetor mixture is correct (a lean condition
can also produce overheating) before flying again.
3.6
Harness Adjustment
The
PJ125Ís harness consists of two separate strapping systems, one used
to comfortably support the paramotor assembly unit on the pilotÍs back
while on the ground, and the other is used to support the paramotor
and pilot while flying. This system also correctly aligns the
thrust angle of the prop. The two systems have separate purposes,
and are adjusted separately.
| |
3.6.1
Ground Handling Straps
In
the Fig.
19, the ground handling straps are in green, the flight
straps are in red.
 |
|
|
Fig.
19
Side and Front Views of Ground Handling Straps and the
flight straps
|
The
ground handling straps as shown above are best adjusted standing
on the ground, with the POWER JET on the pilotÍs back.
The purpose of the shoulder straps and shoulder pads is to carry
the weight of the POWER JET while on the ground.
The purpose of the ground handling chest strap is to keep the
ground handling shoulder straps from falling off the pilotÍs shoulders.
- The
adjustment procedure for the ground handling straps is as follows:
- Strap
into the paramotor and stand up.
- Adjust
the Shoulder Straps until the shoulder pads are carrying the
weight of the paramotor.
- Snug
the ground handling chest strap .
- Adjust
the thigh straps, the tightness of the thigh straps will determine
how easily you can slide into the seat after takeoff.
Adjust these with the use of a simulator.
The
ground handling straps are adjusted correctly if:
- The
weight of the paramotor is on the shoulder pads
- The
shoulder pads/straps wonÍt fall off the shoulders
- The
seat can be moved out from under the buttocks easily
- You
can easily slide into the seat after takeoff
- You
can run easily and the seat and thigh straps donÍt interfere
with your ability to run.
3.6.2
Flight Straps
 |
| Fig.
20
Side and Front View of Flight Straps |
|
In
Fig.
20, the flight straps are red.
The
purpose of each flight strap is as follows:
- Length
ñBî determines the carabiner height. Higher accommodates
larger pilots. Lower accommodates smaller pilots
and provides more weight shift capability. This
length has a variable adjustment locations.
- Length
ñCî is adjusted by buckle ñ5î, and it sets the thrust
angle. Adjust it so the thrust angle is zero to
five degrees below horizontal. This must be done
in a simulator. See ñHang Test in a Simulatorî
below.
- Lenght
"D", is used to adjust the back of pilot's distance
from the PPG.
- Proceed
to final adjusting of the harness in the simulator.
|
3.6.3
Hang-test in a Simulator
It
is HIGHLY recommended that you perform a hang-test in a simulator
before the initial flight of the POWER JET, and every time you
make a harness adjustment thereafter. A simulator can consist
of two ropes tied to a horizontal (and strong) tree limb, two
ropes tied to rafters in your garage or basement, etc.
|

Fig.
21 Carabiner
Positioning
|
|
Once
you have made your initial adjustments, strap into the POWER
JET and clip the carabiners into the simulator. Gently
lift your feet and get seated in the harness.
Continue
to adjust the harness until the following criteria are met:
- The
ground-handling straps should be loose and comfortable
- The
ground handling chest strap should be loose (still buckled,
but loose)
- No
part of the harness should hamper free movement of your
arms and the throttle cable. Make sure you can reach
your arms up very high with no strain or interference
from the harness
- The
propeller shaft must be approximately 5, and no more than
10, degrees below horizontal
|
WARNING!
The carabiner hook-in loop must be located beneath the flight
strap, as shown below in Fig. 15. This orientation places
the pilotÍs weight on the strap itself, rather than on the stitching
of the loop.

4.1ææ
Preflight Inspection
Before
your first flight, and before every flight, it is absolutely essential
to perform a pre-flight inspection on your aircraft.
WARNING!
Failure to perform a sufficient preflight has been a contributing factor
to accidents in all kinds of aircraft. Equipment damage, bodily
injury, even death can occur due to equipment problems not caught in a
preflight inspection. As the saying goes, ñPreflight as if your
life depends on it, because it does!î
NOTE!
Example Pre-Flight Checklists can be found at the end of this manual.
It is highly recommended that you use one of the examples, or create your
own, print it out, laminate it, and use it whenever you fly.
Also
note that these Checklists are examples only, FLY PRODUCTS is not responsible
for their use or for their completeness.
4.2
In-flight Starting
One very valuable feature of the PJ125 is its ability to be started
while in flight. This feature allows the pilot the freedom to turn-off
the engine and glide silently, to enjoy the exhilaration of thermal soaring,
and then when he gets low, to start the engine and climb back up to do
it again. The process of in-flight starting is very simple. First,
release the paragliderÍs brake toggles.
WARNING!
Failure to release the brake toggles before attempting in-flight restarting
could result in excessive braking of the paraglider. This could
result in loss of control, a stall, spin, and possible crash.
Next,
reach up over your shoulder and grasp the start handle. Give the
start handle an aggressive, quick pull. The engine will start. Grasp
the gliderÍs brake toggles, and gently add power.
5.0 OPTIONAL
ACCESSORIES
back to top^
5.1ææ
Tool Kit
It
is highly recommended that a tool kit be assembled and carried in one
of the harness pouches.
The following tools, at a minimum, are suggested for the tool kit:
- Spark
plug wrench (13/16î)
- Metric
Allen wrenches
- Vice Grips
- Combination
wrenches (10mm, 13mm)
- Screwdrivers
(both Phillips and Straight)
5.2
Reserve Parachute
A reserve parachute can be fitted to the POWER JET, and is a highly recommended
safety item. Many different mounting locations and methods are possible
and acceptable, and the one you choose depends on many things such as
which hand you want to deploy with, what type of reserve you have, where
you prefer to mount it (front, left or right side), etc. For this
reason, FLY PRODUCTS cannot make a generalized statement of what the best
mounting configuration is for you. It is highly recommend that you
seek assistance from your PPG instructor on the mounting of your reserve
parachute. It is also highly recommended that you receive training
(a reserve parachute clinic) covering topics reserve deployment topics
such as reserve re-packing and parachute care, performing a PLF (Parachute
Landing Fall), and when to make the decision to deploy your reserve.
WARNING!
A reserve parachute is a life-saving backup system, to be used in life-threatening
emergencies only. A reserve parachute should never be deployed ñfor
funî or to ñsee what itÍs likeî. A reserve parachute deployment
is an extremely dangerous event. You surrender control over your
aircraft, you have no choice as to your landing location and could land
on rocks, roads, power lines, etc. Even with a correctly deployed
parachute, your impact speed with the ground is significant. Also,
reserve parachutes are not guaranteed to deploy correctly. Remember
the expression, ñA reserve parachute isnÍt your second chance, itÍs your
last chance.î Carry a reserve parachute, and deploy it only if it
is absolutely necessary.
5.3
Speed Bar
A speed bar can be mounted to the POWER JET harness. Optional pulleys
can be added to the harness to facilitate the application and routing
of the speed-bar.
These pulleys can be obtained from your POWER JET dealer.
5.4
Fuel Viewing Mirror
A fuel viewing mirror is an excellent optional accessory. A variety
of mirrors are available at local department stores, or a bicycle specialty
store. Look for a lightweight mirror that will mount on the frame.
Hang in a simulator and adjust the mirror for easy viewing of the contents
of the fuel tank.

YOUR POWER JET FOR TRAVEL

6.1ææ
Disassembling for local travel
For
local travel in a car, only partial disassembly is necessary. This
disassembly includes removing the prop cage and prop.
Since there are four (4) prop bolts and only two (2) bolts on the reduction
drive assembly (commonly called ñre-driveî),
it is faster to remove the entire reduction drive assembly than it is
to remove the prop.
6.1.1
Disassembling the Prop Cage
Unclip the hook on the cage net tension string, (Fig. 7) and follow
the reverse procedure as described before in cap. 2.2.
The complete cage is now disassembled and ready for transport.
Now remove the prop and reduction drive assembly. This is done
by removing the two nuts that hold the reduction drive to the engine.
Your
POWER JET is now ready for local transport.
6.2
Disassembling and packing for long-distance travel
Disassembly and packing for long-distance or airline travel requires complete
disassembly of the POWER JET, and then packing into a suitably padded
and protected box for travel. The first steps of the process are
the same as for local travel, except you should remove the prop from the
reduction drive and leave the reduction drive on the machine. The
rest of the process is below:
6.2.1
Fuel Tank drain
For airline travel, make sure you completely drain the tank, and wipe
the inside dry by inserting a paper towel and thoroughly drying tank.
NOTE!
Make sure you check, and comply with, FAA regulations as well as regulations
of the specific airline that you are traveling before taking the machine
aboard an airliner.
6.2.2
Draining All Fuel
With the fuel tank completely drained, start the engine and allow it
to idle until it stops running. At this point, all of the fuel
will have been removed from the carburetor and fuel lines.
6.2.3
Removing The Harness
Remove the top two harness straps that go around the top tube of the
central (engine) frame (or, in case, unhook the two triangular carabines
).
Remove the distance bars from their seating .
Remove the ground handling straps by threading the lower straps up through
the buckles.
This completes the harness removal.
6.2.4
Cage Disassembly
Remove the cage in the inverse order as described before.

7.1 Cleaning
Clean your POWER JET with clean water and a mild soap. Dust and dirt can
be brushed off, or removed with water and mild soap. Grease and oil can
be removed with a good water-based degreaser such as Simple Green.
7.2 Prop
Care
Avoiding Prop Damage
It
is very easy to damage the propeller by sucking up dirt or rocks when
running the motor on the ground. To avoid this, either place the unit
on a sheet of plywood or something similar, or use a nice clean area such
as a nicely mowed yard. An alternative is to strap the motor on and start
it in the standing position.
Prop Balancing
Balancing
of the propeller is very critical. The prop blades are subjected to accelerations
as high as 2000 Gs! Therefore, a weight difference of only 1 gram
can cause forces as high as 2kg. This force will cause a vibration at
the speed of the propeller RPM, and can cause enough vibration to break
welds or tubes of the frame. Therefore, correct prop balance is of the
utmost importance.
There are
several good articles available on the Web at www.poweredparaglider.com,
that explain correct prop balancing. It is highly recommended to perform
the balancing procedure on your prop.
Keeping the
Prop Clean
Wipe
all dirt and oil from the prop when finished flying. Oil, if left on the
prop for long periods of time, can seep into the wood and cause an imbalance.
Store the
Prop Horizontally
When
storing the paramotor, rotate the prop to a horizontal position. This
is because if the prop is stored vertically, moisture and oils in and
on the prop can migrate downward and cause prop imbalance. This phenomenon
can only happen on wood props.
Prop Repair
Small
dents and dings in the propeller can be repaired with a mixture of baking
soda and super glue. The exact procedure is beyond the scope of this manual,
but several very good articles on prop repair are available on the web
at www.poweredparaglider.com. After minor repairs are performed, make
sure that you balance the prop thoroughly.
7.3 Spark
Plug
The recommended sparkplug for the Top 80 motor on the SCT80 is the B9ES.
The resistor version of this plug, the BR9ES is also recommended,
and is particularly helpful at reducing interference on radios or music
devices.
Spark plug
gap is 0.025 (0.635mm). Recommended cleaning and gapping interval
is every 25 hours. Recommended replacement interval is every 50 hours.
7.4 Repairs
Minor repairs can be performed on the prop, cage, cage guard, and harness.
Major repairs should be performed by a trained service technician, or
by Para-Lite.
Para-Lite
provides full repair services including frame, prop, harness, and engine
repairs. Para-Lite also carries all parts and supplies to keep your
POWER JET in top operating condition.
Caution!
Repairs to the harness or any stress-carrying areas of the POWER JET should
only be performed by a certified parachute rigger. If in doubt, contact
Para-Lite.
