Introduction E-Flight’s Odyssey™ EP offers the modeler an ARF (almost ready-to-fly) electric-powered sailplane that is prebuilt to a high level of craftsmanship. It is unique in that it comes with the electric motor installed, complete with preassembled wiring harness saveing a significant amount of construction time. The precovered and trimmed Odyssey EP is a high-quality 2-meter sailplane that can be flight ready in an hour. The world of electric-powered sailplanes is extremely challenging and rewarding.
Additional Required Equipment Radio Equipment • 3 channels (minimum) • 3 standard servos • On/Off switch • 6- or 7-cell sub-C battery • 270-600mAh receiver-pack You will need at least a 3-channel radio system with three servos on an aircraft frequency for use in your Odyssey EP. A standard radio system (4 channels with standard servos) will work fine. Standard size servos will fit into the fuselage of the Odyssey EP. A wood adaptor plate is provided for use with micro servos.
Field Equipment Needed Motor Battery/Charger A standard 6/7-cell battery pack (7.2 - 8.4 v/1500mAh) is suggested to be used to power the electric motor in the Odyssey EP sailplane. The Hangar 9 Aero Peak™ charger can be used to fast charge the motor battery. HAN9500 Optional Field Equipment TX/RX Quick Charger It’s helpful to have a quick charger that can be used at the field to recharge your transmitter and reciever batteries after long flights.

Section 1: Joining the Wing Parts Needed • Right wing panel • Left wing panel • Aluminum wing joiners (Braces) Step 2. Trial fit the two wing joiners (dihedral braces) into one of the wing halves. They should insert smoothly. Now slide the other wing half onto the wing joiners until the wing halves meet. Tools and Adhesives Needed • Scotch tape Step 1. Locate the two wing panels and aluminum wing joiners. Step 3. Tape the wing halves together using scotch tape.
Section 2: Installing Rudder and Elevator Control horns Parts Needed • Horizontal stabilizer with elevator attached • Vertical stabilizer with rudder attached • Nylon control horns (2) • Nylon backplates (2) • 2 mm screws (4) • 2 mm nuts (4) Step 3.Mark the post where the horn will be placed using a felt-tipped marker and drill the marked locations using a 1/16" drill bit. Tools and Adhesives Needed • • • • Medium Phillips screwdriver Felt-tipped Pen Drill Bit: 1/16" Drill Step 1.
Section 3: Installing the Tail Parts Needed Step 3. Locate the vertical tail fin and rudder. • Fuselage • Horizontal stabilizer with elevator • Vertical stabilizer with rudder • Hardware package Tools and Adhesives Needed • Hobby knife • Phillips screwdriver • Blue Locktite • Adjustable wrench Caution: The 2 mm nuts used to mount the tail assembly to the fuselage are small and easily lost. Use great care during that part of the assembly so you do not inadvertly lose these parts. Step 1.
Section 4: Installing the Radio Parts Needed • 3- or more-channel radio system with 3 standard servos and hardware (not included) • Radio packing foam (not included) • Adapter plate if micro servos are used Step 3. Using a Phillips screwdriver, screw the eight screws to secure the servos.
Step 6. Attach the appropriate servo leads to the receiver. Use Velcro® to mount the receiver and receiver battery to the bottom of the fuselage compartment. Step 9. A micro On/Off switch and a single-pole/double-throw switch are installed in the sides of the fuselage near the motor and the radio compartment. The micro switch is to power the receiver and the single pole/double throw switch is an "arming switch.
Step 10. The micro-switch is used to turn the motor on and off in flight. Use double-sided servo tape to attach the micro-switch to the side of the servo as shown below. Step 12. Attach the servo to the plywood servo mount plate using double-sided servo tape. Apply another section of doublesided servo tape to the bottom of the mount plate to attach it into the fuselage. Step 11. A servo is used to activate the micro-switch through the use of the servo arm.
Section 5: Installing the Control Linkages Parts Needed • • • • • Fuselage Pushrod , threaded on one end (1) Pushrod wire, threaded on one end (1) Clevis (2) Clevis keeper (used to keep clevis closed) (2 pieces of fuel tubing 7mm long - not included) Step 3. Make sure the rudder and elevator servo arms are centered, and attach the metal pushrods to the respective servo arms. The control linkage length can be adjusted by threading the clevis at the control horn in or out.
Section 6: Installing the Canopy Parts Needed • Fuselage • Canopy Step 1.Slide in rear canopy pin in pre-drilled hole in rear of the canopy opening on the fuselage. Step 2. Pull back the canopy lever on the top of the canopy and place the canopy pin in the predrilled hole on the front of the canopy area on the fuselage. Section 7: Control Throw Recommendations The control throws listed below are a good place to start.
Section 8: Balancing the Odyssey Parts Needed • Assembled Odyssey kit Tools and Adhesives Needed Step 3. Mark the location of the CG on the bottom of the wing either side of the fuselage. Step 4. Pick up the plane from a level position using one finger under the wing on each mark. Shift the battery location or add lead weight until the plane remains level when you pick it up. • Masking tape • Pencil or pen • Lead "Stick-on" weights (optional) Step 1.
Section 9: Thermal Soaring A key component to soaring is the air mass the sailplane flies in. Also, there is an energy source producing lift, either a warm air thermal (thermal lift), or the wind rising as it meets an obstacle such as a hill or a line of mountains (ridge lift). We will limit our discussion to describing thermal soaring. Since the warming of air is usually a much smaller area than the total area, the thermal updraft will be faster than the cooler downdraft motion of air.
180° Turn Into a Thermal Thermal Forms (Bubble) As you are flying your Odyssey EP, watch it carefully. If you were in a full-size glider, you would be able to feel the "bump" of entering a thermal. Now you must depend on signs the glider gives as it approaches or enters a thermal. When the Odyssey flies near a thermal that is rising, the wing closest to the thermal will also try to rise, causing the aircraft to "rock" slightly.
Section 10: Preflight Checks Step 1. Check that all control functions move in the correct direction. If not, use the respective reversing switch to correct the direction. Elevator Step 2. Check that each clevis is securely snapped into position. Be sure to use the clevis locking devices (small pieces of tubing slipped over the clevis to hold the clevis closed and prevent accidental opening in flight). Step 3. Check that all servo horn screws are tight. Step 4.
Section 11: Test Glide You will need to balance your Odyssey EP™ after you've completed assembly and have installed the receiver, battery, and servos. Use of the stick-on type of weights is recommended and can be obtained at your dealer. Before adding weight to the sailplane, try moving the battery pack to adjust the center of gravity (usually as far forward as possible). We strongly recommend that before you fly your new Odyssey EP, you first perform a test glide.
Section 12: In-Flight Adjustments for Performance and Conditions Once the fundamentals of launch, trim, and control of the Odyssey EP are learned, it's time to consider getting the most out of the it's ability to perform. To do that, one must learn how to trim the Odyssey for maximum performance, whatever the current conditions are at the time.
Section 13: Definitions Activating (Arming) Switch: an external switch that prevents the electric motor from accidentally turning on Harness: a device consisting of wires, switches, and a fuse that connects the motor to the battery Aerodynamics: science of air in motion L/D: lift divided by drag expressed as a ratio; the same as a glide ratio (think of L/D as a glide slope, then, for a given amount of distance, the sailplane moves forward it drops a certain amount.
AMA Safety Code 2001 OFFICIAL AMA NATIONAL MODEL AIRCRAFT SAFETY CODE Effective January 1, 2001 Model flying must be in accordance with this code in order for AMA Liability Protection to apply. GENERAL 1. I will not fly my model aircraft in sanctioned events, air shows, or model flying demonstrations until it has been proven to be airworthy by having been successfully flight tested. 2.
