A QUICK WORD ABOUT SAFETY AND RADIO CONTROL FLYING MODELS
With radio control aircraft, like any hobby or sport, there are certain risks. The operator
of these models is responsible for these risks. If misused or abused, you may cause serious
bodily injury and/or damage to property. With this in mind, you will want to be certain that you
build your model carefully and correctly. If you are not an experienced flier, have your work
checked by an experienced pilot and ask for help in learning to fly the model safely. This
model aircraft is not a toy and must be operated and flown in a safe manner at all times.
Always perform a pre-flight check of the model which includes proper movements of all
control surfaces, proper function of the radio gear, structural integrity, and radio range.
Models are not insurable but operators are. You can obtain coverage through
membership in the Academy of Model Aeronautics (AMA). For an AMA information package
call 1-800-435-9262, ex t. 292 or visit the AMA website at "www.modelaircraft .org".
By the act of using the final assembled model, the purchaser/operator accepts all
resulting liability.

Note: As with all kits, it's a good idea to read all the instructions and study the parts before you
begin construction. Handle the parts of this kit with care so you do not damage any of the
structure or covering. Inspect all the parts for any shipping damage and report any issues to
Slipstream dealers as soon as you can. Make sure you have a flat and sturdy workbench and
follow all safety advice for the tools and adhesives you plan to use.
AIRCRAFT COVERING:
1. With all ARFs, varying temperatures and storage delays can cause the covering
material to loosen over time during transportation; Slipstream recommends lightly going over
all the covering with a covering iron set at medium temperature. Be sure to use a soft
covering over your iron so that you do not scratch the covering surface. Be sure you go over
all seams and edges of the covering to assure it is secure to the airframe and other covering.
Be careful not to apply too much heat or you may cause bubbles or damage to the covering, A
heat gun may also be used along with a soft cotton cloth to shrink loose coverings. Be
extremely careful when using a heat gun.
2. Be sure to seal any exposed wood with a thin coating of epoxy to prevent engine oil
from soaking in. This is especially important around the engine compartment and servo
openings with exposed areas.
3. Some modelers prefer to seal the hinge gaps using strips of appropriate covering or
clear trim tape. We have found this to be helpful with models intended for higher speed flight
or models with unusually large hinge gaps. Slipstream aircraft utilize a very tight double
beveled hinge line and do not normally require this step, Sealing t he hinge caps is therefore
left as an option for the modeler.
RUDDER AND TAIL GEAR INSTALLATION:
1. Locate the tail gear assembly and install it as shown in the picture below.. Center
the tail wheel bracket on the rear of the fuselage and screw in place using three of
the supplied wood screws. Remove the screws and harden the holes with a drop
of thin CA. Allow the CA to cure and then permanently install the tail wheel bracket.
1.
1. Locate the rudder and the required CA hinges. The rudder is pre-slotted to accept
these hinges. Trial fit the rudder. Ensure that the tail gear rod install smoothly into
the rudder. Harden the hole using thin CA.
2. Once the fit is checked for correctness, glue in the rudder.
3. Locate the pushrod for the rudder slide it in. Place the rudder servo in the tray as
shown in the picture below. The rudder servo will be offset to the left.
4. Using the pushrod as a guide, mark the location of the control horn. Install the
clevis and horn.
LANDING GEAR ASSEMBLY:
2. Locate the supplied main landing gear parts and sort them out on your workbench.
3. Bolt the main gear to the bottom of the fuselage using the supplied bolts. Use a
small drop of thread-lock to secure the bolts in place. Use an appropriate wrench to
hold the blind nut in place while securing the bolt.
4. Install the main wheel axles to the composite landing gear and tighten the nyloninsert lock nut. Install one wheel collar onto the axle. Use second wheel collar as a
guide to achieve a gap on the inboard of the axle. Use a small drop of thread-lock
and tighten in place. Slide the wheel onto the axle and install a second wheel collar
also using thread-lock on the set screw.
5. Locate the wheel pants and install them as shown in picture below. The pants are already
pre-aligned for your convenience.
ENGINE EXHAUST & FUEL SYSTEM INSTALLATION:
1. Use the provided template that comes with your engine (if provided) to align the
engine. The center line for the mounting of the engine is marked on the firewall.
2. Use the guide to align the engine and drill the mounting holes. You may have to
cut the firewall as necessary if using a rear-carburetor engine. Notice that the
engine center line is offset to the 1eft to compensate for the right thrust built into
the engine box.
.
3. Place the cowling in place on the fuselage and measure the distance from the
firewall to about 0.5 inch in front of the cowling. This figure represents the back of
the spinner and will help you determine if you need to space your engine out from
the firewall using washers or additional wood. Mount your engine securely using
bolts, washers. and locknuts and according to the manufacturer's instructions. The
use of thread-lock is also highly recommended for the engine bolts. The pictures
below show the different type of engines that can be mounted (side of rearcarburetor).
4. Mount the ignition module according to the manufacturer's instructions. Secure
the pickup lead and ignition wires with zip ties so that they do not vibrate or touch
any hot part of the engine or exhaust. The author prefers to protect the ignition
wires with cable wrap to prevent wear of the mesh shielding,
5. Mount your ignition battery securely to the engine box. A good location is just
above the engine. The ignition switch should be mounted to the fuselage side wall
just behind the cowling, Secure all wiring connection neatly and firmly. See
pictures below for a typical setup.
6. The fuel tank is pre-assembled. Complete the installation in the fuselage using zip
ties or velcro straps to hold the tank in position. Connect a fuel line between the
tank and carburetor, a fuel line between the tank vent and the bottom of the
fuselage, and a fill line to a fueling dot which can be mounted to the fuselage side
opposite your ignition switch. Make sure your vent line does not come close to
any hot exhaust part such as the muffler. Slipstream recommends the use of
small zip ties or fuel line clamps to secure the lines to the tank.
COWLING INSTALLATION:
1. Fit the cowling in place and make any cutouts necessary to clear your engine and
exhaust components. Trial fit and trim as necessary being careful and accurate.
Use a spinner back plate to help alignment. Be sure to allow enough air exit area
in the bottom of the cowling to provide adequate airflow over the engine. When
satisfied with the final fit, attach the cowling to the fuselage using the supplied
screws.
2. Install the propeller and spinner. Gasoline engines are very powerful and can
cause damage to persons or property if propellers and spinners are not installed
properly. Follow the manufacturer's instructions and make sure your propellers
are well balanced, properly drilled, and display no cracks or chips.
HORIZONTAL STABILIZER AND ELEVATOR CONTROLS ASSEMBLY:
1. Locate the one piece stabilizer. Slide it in the stabilizer cutout in the back of the
fuselage and center it. To ensure squareness of the assembly, measure the
distance of the trailing tip of the wing to the trailing tip of the stabilizer on both
sides. Make sure that they are equal. Once this is done, mark the area where the
stabilizer meets the fuselage with a fine marker. Remove the stabilizer from the
fuselage and carefully cut the covering off.
2. Prepare some 30 minute epoxy. Have some paper towels soaked in isopropyl
alcohol to wipe off the excess epoxy. Apply the epoxy over the expose area of
the stabilizer and reinstall the stabilizer onto the fuselage. Wipe off the excess
epoxy. Redo the measurement to ensure the squareness and center of the
stabilizer. Set it aside and let to allow the glue to dry.
3. Locate and prepare the CA-hinges for installing the elevators onto the stabilizer.
Employ the same method that was used to install the rudder.
4. Locate the pushrod for the elevators. This pushrod is “Y-ed”. Carefully insert
them through the opening in the rear. Install the servo in the center of the servo
tray in the fuselage. The arm of the servo must be centered t prevent adding bias
to the throw of the elevators. An optimal way is to side mount the servo as shown
in picture below. This will ensure no biases in the throw.
5. Use the pushrod to mark the locations of the control horns. Once satisfied, install
the horns and clevises.
6.
WING AND AILERON CONTROLS ASSEMBLY:
1. Locate the servo mounting plate and blocks. Glue the blocks onto the plate
using your servo as a guide. Ensure that the servo arm exits smoothly without
rubbing the exit slot.
2. Use your radio and ensure the centering and direction of the servo. Once that is done,
mount the servo plate onto the wing as shown in the picture above.
3. Install the ailerons using the provided CA-hinges and glue them in just like the
installation of the rudder.
4. Line up the pushrod and mark the location of the horn. Install the horn as shown in the
picture above.
BALANCING AND PRE-FLIGHT:
The CG location for this aircraft is right on the spar.
Recommended control surface deflections:
Elevator 15 degrees 30 degrees
Low Rate High Rate
Rudder 25 degrees 40-45 degrees
Ailerons 25 degrees 35 degrees
FINAL ASSEMBLY AND PRE-FLIGHT INSPECTI0NS:
1. Before arriving at your flying field, be sure all your batteries are properly
charged and all radio system are in proper working order.
2. Install the wings onto the using the provided nylon bolts.
3. Fill your fuel tank making sure your vent line is not plugged or capped. With the
canopy off, this is a good time to check for any fuel leaks.
4. Check all control surfaces for secure hinges by performing a slight tug on the
control surfaces and observing if there is any give in the hinges. Check all
control rods, ball links, servo screws, etc. for proper operation and installation.
5. Check your batteries and perform a proper range check once again with the
engine off and running. Be sure all surfaces are moving in the correct direction
and the proper amount for your flying setup.
