Relationshipware StratoLauncher IV User manual

* Polyethylene terephthalate (aka PET) is a thermoplastic polymer
resin of the polyester family that is used in soda pop bottles. Seri-
ous bodily injury could result from using any other type of bottle.
Tools required for assembly and items needed to launch rocket:
An adjustable wrench (or a 14mm wrench), 4mm & 5mm hex wrench, and
Phillips head screwdriver. A plastic (PET*) soda bottle, nose cone, water,
and air source (bicycle pump, foot pump, scuba tank, or an air compressor).
Soda bottle nose cone is required or rocket will not fly straight:
Create the nose cone by starting a cut with a razor blade or box cutter
about 4" down from the cap and just above the label of a plastic (PET*)
soda bottle. Finish cutting around the bottle with scissors in a straight line.

Check for Leaks
Before heading to the launch field, check
that all seals do not leak. Add a cup of wa-
ter to the bottle. Place bottle onto the
launcher & press down until it locks with a
loud click. Pressurize to 80 PSI with pump
& see if any water is escaping around the
threaded holes of the manifold. If so, pull
the ring on the relief valve to release pres-
sure, than tighten the leaking fitting(s).
Relief valve slits should face sideways to
avoid spraying into eyes when it releases.
Assemble Launcher
With the black cable stop facing you screw
brass parts into the manifold beginning at
the upper left and work clockwise. If no red
sealant, wrap 3 Teflon tape layers around
part threads first. Screw in black hose con-
nector on top. Attach clamp-on cable stop
over hose connector & align. Do not over
tighten clamp as connector will bind /break.
Optional, wrap Teflon tape around threads
of 1/4" SS tube to keep water out of the air
chamber below before screwing it in place.
Mount assembled launcher onto the ABS
base with the SS Phillips screw. Stretch
out brake cable & place fat barrel nipple
into the brake lever slot, thread through,
and secure with silver slack adjustment
ring. Insert other end of cable housing into
manifold cable stop, push hose connector
down & place nipple into clamp-on cable
stop. Remove excess brake cable slack by
ring or screwing in Phillips screw on lever.
Increase or decrease brake cable slack by
raising or lowering clamp-on cable stop.
Upgrade Part Tips
Wrap 3 to 4 layers of Teflon tape clockwise
around threads with threads facing you;
insures that tape won’t come off while
threading into hole. Air pressure gauge &
mini ball valve need to be aligned to face
toward the top or angled slightly to the
front. More wraps of Teflon tape may be
needed for these 2 parts to properly align
on the manifold. Water will run off better
when gauge is installed at an angle and
will read better when launcher is tilted.
Assemble Accessories
Attach brake lever to PVC handle if sepa-
rate. Insert black reducer into collapsible
funnel. See next page for assembling the
StratoFins and creating a nose cone from
a 2 liter soda bottle. Screw black nozzle on
to StratoFins or your homemade rocket.

StratoLauncher® IV Assembly Instructions

Tips & Troubleshooting:
Be sure to use wrenches when screwing in the gauge, valves, and fittings. Do not attempt to screw them in by hand other than getting them
started. This is particularly true for the pressure gauge as the housing will provide good leverage, but you will break the gauge in the process. Use
the appropriate size wrench (14 mm ideal or adjustable or 9/16 inch will work okay) on the hex portion of these items.
Be sure to remove the gasket over the nozzle and place it inside the screw cap area.
If your kit comes with the ball head, but you do not want a user to be able to angle the launcher, you do not need to install the ball head.
Positioning gauge, valves, & fittings:
With threads facing you, wrap Teflon tape clockwise around threads to insure that it won’t come off while threading into a hole.
Wrap at least 4 layers of Teflon tape clockwise around threads of the air pressure gauge and the mini ball valve before screwing them into the top
holes. This will keep these from leaking and help with alignment of these two units. The other fittings one can keep screwing in, but due to proper
positing of the gauge and valve you will not be able to keep screwing them in all the way.
Screw in air pressure gauge first on the upper left side hole if your kit comes with this part.
Next screw in mini ball valve on the upper right side hole if your kit comes with this part.
Air pressure gauge and mini ball valve need to be aligned to face toward the top or angled slightly to the front. More wraps of Teflon tape may be
needed for these 2 parts to properly align on the manifold. Water will run off better when gauge is installed at an angle and will read better when
launcher is tilted at an angle.
Air pressure safety relief valve slits should face sideways to avoid spraying into one’s eyes should it open during pressurizing.
Do not over tighten clamp-on cable stop over hose Q-Release connector, since it might bind (reduce up and down movement from internal spring
action) or possibly even crack the plastic hose Q-Release connector sleeve.
Ball Head Adjustments:
Ball head will NOT lock in place if the attachment plate inside at the bottom is unscrewed too far. One can rotate the ball head from the base;
however, if it is rotated too far it will not make contact with the ball and therefore will not lock in place. Solution: you may need to loosen Phillips
head screw in ABS base to allow the ball head plate to screw back up inside to make contact with the ball head.
When adjusting the angle of the launcher lean it toward the left of the lever, since this has the slot enabling it to move a greater distance. Also,
when launching at an angle release the rocket when you are positioned on the side of the lever. If you are behind the rocket on an angled launch
you will get sprayed with water when it takes off.

Brake Cable and Lever Adjustments:
The remaining cable outside the black housing will shorten when the brake cable is coiled up; therefore, do not leave it attached to the launcher
when you coil it up since it will compress the springs inside the Q-Release hose connector. If you look closely at our pictures with this coiled
arrangement you will see that the other end is not attached to the brake lever, but laying underneath of it. This arrangement was for picture taking
purposes and it is better to keep the cable attached to the brake lever and remove the cable from the launcher when being stored.
When taking up slack in the brake cable, start with the slack adjustment barrel and back it out several revolutions and lock with the outer ring. If
more slack needs to be removed turn the Phillips screw beside it in and this will adjust the throw distance of the brake lever. Do not remove all the
travel out of the lever throw or you won’t be able to pull the Q-Release hose connector down to release the rocket. If even more cable slack needs
to be removed than raise the clamp-on cable stop on the Q-Release hose connector. Between these 3 adjustments you should be able to take up
any extra slack in the cable length.
If the cable is not long enough make sure the Phillips screw is mostly turned out on the lever throw. Make sure the adjustment barrel is turned all
the way inside so no slack is being taken up. Thirdly lower the position of the clamp-on cable stop on the Q-Release hose connector, which will
require less cable to reach the clamp-on cable stop.
Spray WD-40 or similar lubricate inside the brake cable housing on the side closest to the launcher will help the cable move easily inside and
keeps moisture out for longevity.
These troubleshooting tips should solve any issues you might have. If you encounter additional problems, please let us know and we will update
these troubleshooting tips with additional solutions.
Thank you for your purchase and we hope you enjoy your new StratoLauncher IV for many years to come.

StratoFins
®
Instructions & Information
Please read through the StratoFins® instructions carefully to opti-
mize flight performance with your specific style launcher. Launch
rocket with extreme care and only under adult supervision.
Launching rocket with a nose cone improves performance:
A nose cone makes a rocket aerodynamic for straighter flights. StratoFins
will work on most launchers with air pressures of 10 to 120 PSI, but best
results occur between 40 to 80 PSI with a nose cone resting atop the rocket.
StratoFins®* Kit Includes:
Attachment ring (1)
Fins (3)
* StratoFins®: are compatible with 95% of all available
launchers either homemade or commercially available
in the marketplace including those employing a rubber
stopper, an expanding tube, nozzle, O-ring, or cable
ties because it replicates the threaded portion of the
bottle beyond the fins.
Place Nose Cone:
Right before launch place the nose cone
on top of the water rocket. Do NOT secure
it in any manner. Notice the gap (notice
arrow) between it and the bottle. During lift
off the air pressure holds the cone in place.
When the rocket reaches apogee and be-
gins to turn, the cone falls off thus prevent-
ing the rocket from nose diving into the
ground and causing potential damage to
the rocket and public or private property.
Assemble StratoFins:
Assemble StratoFins by sliding each fin
down a separate slot on the attachment
ring beginning from the top. With all fins in
place screw the attachment ring onto a
soda bottle until snug. Works ideally with a
2 liter soda bottle, but smaller sizes can be
used. This water rocket can be launched
with or without a parachute attached since
this configuration does not nose dive, but
instead tumbles gently back to the ground.
* Stratofins® require no tools or glue for assembly.
Construct Nose Cone:
Create a nose cone from the top of a 2 liter
bottle by starting a cut with a razor blade or
box cutter about 4" down from the cap and
just above the label of a plastic (PET**)
soda bottle. Finish cutting around the bottle
with scissors in a straight line. Cut around
the nose cone again if necessary to
smooth and straighten the bottom edge of
your new nose cone.
Assorted Rockets:
Various rockets and launchers can be
used with the StratoFins from different size
soda bottles to FTC (Fluorescent Tube
Cover) rockets and more. A truly versatile
product for many applications.
Replacement Parts
Replacement parts, upgrade kits, videos,
and future accessories can be found at our
website.
.
* An optional flagging tap streamer about 2 ft. long
can be attached inside the nose cone with the cap
screwed over one end as shown above to help locate
the cone after launching.

*** If the bottle fails to release from the launcher or it is aimed in an
unsafe direction and you are exceeding 120 PSI, then ABORT your
launch. Carefully pull the safety valve ring to release the air pressure
within the bottle; than one can remove the bottle from the launcher.
StratoLauncher®IV Launch Instructions
Please read operating instructions carefully before launching
any plastic bottles. Designed for ages 10 and over. Operate
launcher with extreme care and only under adult supervision.
WARNING: Do NOT allow anyone to touch the bottle after pumping has
begun. Do NOT aim the bottle at anyone or any other object, either public
or private. Do NOT stand over the bottle. Do NOT impact the bottle under
pressure as it may shatter. Do NOT exceed 120 PSI inside the bottle.
Safe & Secure
Choose a safe area such as a huge field or
park away from people, trees, and resi-
dences to launch plastic bottles (rockets).
Although no pulling action against the
launcher is required to release the rocket,
securing the base with 1 or 2 tent pegs
(not included) may help avoid accidental
tip over during use.
Launcher supports most .5L, 1L, 1.25L and
2 liter plastic (PET*) bottles.
Mount Rocket
Tilt the entire launcher to the side, parallel
with the ground, and slide the bottle over
the 1/4" SS tube. Press the bottle against
the Q-Release hose connector until it locks
with a loud click. Place the launcher on the
ground and secure with tent pegs if de-
sired. Alternate method: hold your finger
over the nozzle and place the bottle above
the 1/4" SS tube, then rapidly remove your
finger and push the bottle over and down
the tube and lock in the hose connector.
Prepare Trigger
Fully stretch out the brake cable on the left
side of the launcher parallel with the tank
valve. Insert the black cable housing into
the manifold cable stop, push Q-Release
hose connector down & place nipple into
clamp-on cable stop. Remove any excess
cable slack with brake lever adjustments.

plastic polymer resin of the polyester family that is
used in soda pop bottles. Serious bodily injury could
result from using any other type of bottle.
Funnel Fill
Inspect your PET* bottle for any damage
or potential problems. If in doubt discard
the bottle and employ another.
Use only water and/or air for fuel.
Insert the red funnel into the bottle & fill the
funnel to the brim quickly and stop pouring.
This will yield the ideal amount of 1 cup
(notice the water level near the score mark
on the 1/4" SS tube when the bottle is
mounted on the launcher).
Water Fill Upgrade Kit
StratoLauncher IV Ultimate kit contains an
upgrade kit that can be purchased sepa-
rately, which enables the use of a tank
sprayer (available at local hardware stores)
as your water fill source. A 2 gal. tank will
yield about 30 launches. Pressurize the
tank by pumping 10 or more times. Open
the mini ball valve on the launcher until the
water level touches the score mark on the
1/4" SS tube, and then close for efficient
and spill free fueling.
Pump & Launch
Attach the air source** to the Schrader
valve on the launcher. Be sure all persons
are at least 10 feet away from the
launcher, then begin pumping. Launcher
supports air pressures between 10 PSI up
to 120 PSI***. Stop pumping once you
achieve the PSI that you desire. Place
nose cone on rocket. Squeeze the brake
lever from a safe distance and out of the
splash zone to launch the rocket. Enjoy!
** Sources for compressed air include a bicycle pump,
a foot pump for a car, scuba tank, or air compressor.
