Airframe Assembly Required Parts Vertical fuselage Horizontal fuselage Wing w/ailerons Stabilizer w/elevators Motor mount 2. Locate the wing and slide it into the vertical fuselage underneath the horizontal fuselage. Use care not to damage either the vertical or horizontal fuselage pieces. Required Tools and Adhesives Foam-compatible CA, Medium Foam-compatible accelerator (can be used to speed up cure time) Square 1. Locate the vertical and horizontal fuselage pieces.
3. Slide the horizontal stabilizer into the fuselage, being careful not to damage any of the alignment tabs. You may need to move the horizontal fuselage out of the vertical fuselage slightly to get the stabilizer into position. Note: Trim the hinge tape at the rear of the stabilizer to provide clearance of the alignment hole. 4. Align the wing with the horizontal fuselage. Use foam-compatible CA to glue the wing to ONLY the horizontal fuselage.
10 5. Measure from the wing tip to the elevator tip on each side of the airframe. The measurements will be the same when the stabilizer/elevator has been aligned with the wing. Use T-pins to hold the stabilizer in position for the next step. 6. Use foam-compatible CA to glue the stabilizer to ONLY the horizontal fuselage.
7. Place the motor mount in position to aid in the alignment of the vertical and horizontal fuselage pieces. DO NOT glue the mount until instructed to do so. Position the horizontal and vertical fuselage pieces until the mount rests flush against both. 8. Apply foam-compatible CA to the joint between the vertical and horizontal fuselage pieces from the leading edge of the wing to the front of the fuselage. Use a square to make sure the two pieces are aligned.
Installing the Bracing 1. Locate the two 4.6-inch (117mm) carbon rods. Pass the rods through the fin and stabilizer. Butt the rods together in the fin and use foam-compatible CA to glue the rods to the fin ONLY at this time. 2. Use a square to align the stabilizer with the fin. Once the fin is perpendicular to the stabilizer, use Foam-compatible CA to glue the carbon rod to the stabilizer. Square each side before gluing the rod on that particular side.
3. Position the carbon rods in the fuselage, gluing the rods to the vertical fuselage ONLY. This will allow for alignment of the fuselage in the next step. Note: The length of the rods are: XL = 5.9-inch (150mm) L = 4.3-inch (110mm) M = 3.9-inch (100mm) S = 3.75-inch (95mm) E-flite Sobré 3D Profile Assembly Manual 4. With the airframe upright, check that the stabilizer is parallel to the wing. Lightly twist the fuselage as necessary for alignment. 5.
Important: Make sure to use eye protection when cutting the carbon rods. 6. Installing the wing bracing is similar to installing the fuselage bracing, as you want the rods to be glued to the carbon bracing that has been preinstalled on the wing and fuselage. The longer 12.7-inch (323mm) rod is positioned toward the aileron, while the shorter 12-inch (305mm) rod is toward the leading edge. The rods are staggered and fit into notches in the fuselage.
2. Install the elevator micro control horns at this time. Make sure the rudder horn extends opposite of the elevator horn. 4. Remove the servo arms from the four servos. Drill a 1/16-inch (1.5mm) hole in the end of all four of the servo arms. Note: We then suggest using the longest servo arms available for your servo to help achieve maximum control throws for 3D flying. 3. Install the rudder micro control horns at this time as well.
6. Plug the servos into the receiver. Turn on the transmitter and receiver and check the operation of the servos. After centering the trims and sub-trims, attach the servo arms as shown. Note the direction of the arms on the servos. 7. Use hot glue to install the aileron servos. 8. Install the rudder and elevator servos using hot glue. The output shafts of both servos face the front of the aircraft.
9. Locate the 4.5-inch (115mm) pushrod. Install the “Z” bend into the middle hole of the control horn that is one away from the aileron. Pass the pushrod through the connector. Check that the aileron servo is centered using the radio and parallel to the aileron hinge line. Hold the aileron parallel to the wing and use the 2mm x 4mm screw in the connector to secure the pushrod wire. Repeat for the other aileron pushrod. 10. Install the 19.25-inch (490mm) pushrod for the rudder, and the 18.
Motor and Battery Installation Required Parts Airframe Plywood motor mount Motor w/hardware Electronic speed control Propeller #2 x 8mm or #3 x 8mm wood screw (included with motor) Hook and loop material Note: The rudder and elevator pushrods attach to the inside hole of the control horns. 18 11. Install the receiver using hook and loop material. The exact position of the receiver may change, depending on how your aircraft balances.
1. Locate the plywood motor mount and aluminum X-mount for your particular motor. Center the motor mount on the plywood and mark the holes for the mounting screws using a felt-tipped pen making sure the holes you mark do not interfere with the carbon spars the mount will glue into. 2. Drill pilot holes for the mounting holes marked on the plywood mount using a 1/16-inch (1.5mm) drill bit.
3. Reposition the shaft on the motor as shown to allow the use of the propeller adapter. Make sure to secure the shaft using instructions included with your motor. 4. Attach the mount to your particular motor. 5. Attach the motor to the plywood mount using two #2 x 8mm wood screws or two #3 x 8mm wood screws.
6. Place the plywood motor mount in position. Make sure the mount is tight against the vertical and horizontal fuselage. Trim the fuselage as necessary to provide clearance for the motor leads. Use Foamcompatible CA to securely glue the mount to the vertical and horizontal fuselage. 7. Solder any necessary connectors to your speed control. Plug the speed control into the throttle channel of the receiver and to the motor. Use hook and loop to secure the speed control to the fuselage.
8. Turn on the transmitter and bring the throttle trim and stick to the low throttle position. Plug the battery into the speed control and check the operation of the motor. It should rotate counterclockwise when viewed from the front of the aircraft. Use the instructions provided with your ESC to make corrections to the direction of rotation of the motor if necessary. 9. Install the propeller using the instructions provided with your motor or propeller system.
Optional Variable Pitch Prop Installation 2. Install the propeller using the instructions provided with your motor or propeller system. Note: The following outlines the installation of a VPP for your Sobré. Be sure to consult the manual for your chosen variable pitch prop unit before proceeding with installation of the pitch servo and linkage. Due to the variety of VPP systems available, there may be some variation in how the servo and linkage can be installed.
Landing Gear Installation Required Parts Airframe Landing gear strut (2) Wheel retainer (4) Wheel pant (2) 1.5-inch (38mm) foam wheel (2) Landing gear support disk (2) Note: Use care not to get CA on the wheel, preventing it from rotating on the strut. 2. Pass the landing gear through the opening in the fuselage and wing. DO NOT use glue until instructed to do so. 3. Repeat Steps 1 and 2 for the remaining strut. Required Tools and Adhesives Foam-compatible CA The landing gear is optional.
4. The struts should extend roughly 3/32-inch (2.5mm) through the top of the wing. This will give the landing gear support disks plenty of strut to attach to. Hint: You can just drop the disks into position and check to make sure the strut extends beyond the disk instead of measuring it. 6. Install the landing gear support disks using foamcompatible CA. Make sure to glue the disks securely to both the horizontal fuselage and landing gear struts. 7.
Installing the Optional Side Force Generators Required Parts Side force generator (upper) (2) Side force generator (lower) (2) Carbon rod, 4.3-inch (110mm) (4) 2. Locate a 4.3-inch (110mm) carbon rod. Position the rod in the predrilled holes in the SFG and wing. Use foam-compatible CA to glue the carbon rod to the SFG ONLY at this time. Required Tools and Adhesives Foam-compatible CA Square Note: The side force generator (SFG) installation is optional.
3. Glue the bottom SFG into position. Glue the 4.3-inch (110mm) carbon rod to the SFG. Check that the top and bottom SFGs are still perpendicular to the wing. Use Foam-compatible CA to glue the carbon rods to each other and to the wing. Battery Installation Required Parts Battery Hook and loop tape 1. Use hook and loop tape to secure the battery to the underside of the wing. The location of the battery can be adjusted to correct for the Center of Gravity described later in this manual. 4.
Control Throws Turn on the transmitter and receiver of your Sobré. Check the movement of the rudder, elevator and ailerons using the transmitter. Reverse the direction of the servos at the transmitter if necessary. Use a ruler to adjust the throw of the elevator, ailerons and rudder. Adjust the position of the pushrod at the control horn to achieve the following measurements when moving the sticks to their endpoints. Measurements are taken at the widest point on the surface.
Center of Gravity Caution: Do not inadvertently skip this step! Range Testing the Radio 1. Be sure to range check your radio before each flying session. This is accomplished by turning on your transmitter with the antenna collapsed. Turn on the receiver in your airplane. With your airplane on the ground and the engine running, you should be able to walk 30 paces (approximately 100 feet) away from your airplane and still have complete control of all functions.
Preflight Check Your Radio Before going to the field, be sure that your batteries are fully charged per the instructions included with your radio. Charge both the transmitter and receiver pack for your airplane. Use the recommended charger supplied with your particular radio system, following the instructions provided with the radio. In most cases, the radio should be charged the night before going out flying. Before each flying session, be sure to range check your radio.
