Recommended Radio Equipment You will need a minimum 4-channel transmitter, receiver, and three servos. You can also choose to purchase a complete radio system. If you are using an existing transmitter, just purchase the other required equipment separately. We recommend the crystalfree, interference-free Spektrum™ DX6i 2.4GHz DSM® 6-channel system. If using your own transmitter, we recommend the 6.0 Gram Super Sub-Micro Digital Programmable Servos from Spektrum.
Fuselage Construction Required Parts Main fuselage Stabilizer Depron firewall Left horizontal fuselage Right horizontal fuselage Left upper diagonal brace Right upper diagonal brace Left lower diagonal brace 1. Locate the left horizontal fuselage and main fuselage. The left horizontal fuselage will be printed on top and white on the bottom. Test fit the horizontal fuselage to the main fuselage. Check that the horizontal fuselage lines up at the front with the main fuselage. 2.
4. Position the horizontal fuselage on the main fuselage, again making sure that they line up at the front. Use a square at multiple points on the fuselage from nose to tail to guarantee the horizontal fuselage is square to the main fuselage. Check square from both the top and bottom side of the fuselage. Allow the CA to fully cure before proceeding. 5. Position the left upper diagonal brace as shown. Use the alignment point in the photo to properly position the brace.
6 7. Locate the horizontal stabilizer. Note the coloring scheme on the top of the stabilizer. Carefully fold the elevator on the stabilizer as shown so it can be installed into the fuselage. 8. Slide the folded horizontal stabilizer into the fuselage. Unfold the elevator and position the stabilizer, but do not apply any glue to the stabilizer at this time. 9. Repeat Steps 1 though 5 to install the right upper diagonal fuselage brace with foam-safe CA.
Wing Installation Required Parts Fuselage assembly Bottom wing Top wing Outer strut (2) 2. Test fit the fuselage into the bottom wing as shown. Make sure the tabs from the fuselage are flat when inserted into the bottom wing. If not, you may induce an airfoil resulting in unwanted flight characteristics. 3. After confirming the fit between the fuselage and bottom wing, use foam-safe CA to glue the bottom wing to the fuselage.
5. Test fit the outer strut into the bottom wing as shown. Make sure the tab is flat when inserted into the bottom wing. If not, you may induce an airfoil resulting in unwanted flight characteristics. 6. After confirming the fit between the outer strut and bottom wing, use foam-safe CA to glue the outer strut to the wing. Use a square between the outer strut and bottom wing to keep them in alignment while the CA fully cures. 8 8. Locate the top wing.
Carbon Bracing Installation 2. With the top wing flat on your work surface, check that the struts and fuselage are square to the top and bottom wings. Apply a small amount of foam-safe CA at the points where the carbon rod are inserted in the top wing. The rod should be inserted completely through the wing but should not protrude past the top of the wing. 3. Make sure to keep the airframe very square while proceeding.
4. Using a square, install the 4 1/8 x 1/32-inch (105mm x 1mm) carbon rods between the left and right outer struts and bottom wing as shown. Make sure to keep the bottom wing flat on your work surface and not to deflect the outer struts between the top and bottom wings when installing the carbon rods. 6. Use foam-safe CA to install the two 5 5/16 x 1/32-inch (135mm x 1mm) carbon rods between the top wing and fuselage as shown.
8. While keeping the stabilizer in alignment, apply foam-safe CA to the left and right horizontal fuselage as well as the left and right diagonal braces to secure them to the fuselage and stabilizer. 10. Use foam-safe CA to install the two 5 3/4 x 1/32-inch (145mm x 1mm) carbon rods that brace the stabilizer. Use the drawing from Step 8 as a guide for positioning the stabilizer. It must be parallel to the top and bottom wings, as well as straight across and flat as shown.
12 2. Use medium grit sandpaper to sand an angle on one end of each of the two 6 7/8 x 3/32-inch (175mm x 2.5mm) carbon rods. This angle should be around 45-degrees and will allow the carbon rods to fit against each other to provide a much stronger landing gear assembly. 3. Test fit the two carbon rods in the aircraft as shown. Once the fit is acceptable, and the airframe will sit level, use foam-safe CA to glue the carbon rods into position. Allow the CA to fully cure before proceeding. 4.
Motor Installation 2. Use medium grit sandpaper to lightly sand the back side of the firewall. The glue will be applied to this side of the firewall to attach it to the fuselage. 3. Match the two alignment points to those in the Depron firewall (top and left as viewed from the front of the fuselage). Use foam-safe CA to secure the firewall to the fuselage. Required Parts Assembled airframe Motor Transmitter Speed control Right lower diagonal Carbon firewall Receiver Motor battery 4.
6. Use a #1 Phillips screwdriver and the two screws provided with your motor to attach it to the firewall. Work slowly to avoid applying too much pressure, resulting in damage to your airframe. 8. Check the operation of the motor at this time. It should rotate counterclockwise when viewed from the front of the aircraft. If not, follow the instructions provided with your speed control to correct the situation. Never check the motor rotation on the bench with the propeller installed.
. Use foam-safe CA to glue a carbon rod to 2 the control horn support as shown. Assemble four control horns at this time. 3. Use a T-pin to poke a hole in the hinge tape for each of the bottom ailerons, rudder and elevator. 4. Use foam-safe CA to glue the control horns in position. Make sure the control horn supports are perpendicular to the hinge line on each of the control surfaces.

Plug the rudder, elevator and aileron servos into their corresponding ports of the receiver.
6. Test fit the aileron servo in the hole in the bottom of the bottom wing. The output of the servo will face the tail of the aircraft. Once fit, use a lowtemperature glue gun or foam-safe CA to adhere the servo to the wing. 7. Plug the servos into the receiver at this time. You may need to plug an adapter in the receiver to connect the lead from the speed control as well. Use hook and loop tape to secure the receiver to the fuselage.
18 9. Locate three of the pushrod supports and slide the supports onto the pushrod as shown in the second photo. 10. Insert the pushrod guides into the slots in the fuselage. In each position, there is a pair of holes. The rudder pushrod supports go in the rear hole of each pair. Do not glue the supports yet. 11. Align the pushrod with the rudder control horn. 12. The pushrod is supplied slightly long to accommodate for servo selection and control horn position.
14. Use a soldering iron to shrink the tubing to secure the pushrod to the control horn. 16. Insert the bend of the 23 5/8-inch (600mm) elevator pushrod into the servo arm. Use the second hole in from the end of the servo arm as shown. 18.

Control Throws 1. Turn on the transmitter and receiver of your model. Check the movement of the rudder using the transmitter. When the stick is moved right, the rudder should also move right. Reverse the direction of the servo at the transmitter if necessary. 2. Check the movement of the elevator with the radio system. Moving the elevator stick toward the bottom of the transmitter will make the airplane elevator move up. 3. Check the movement of the ailerons with the radio system.
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. Range Test Your Radio Before each flying session, be sure to range check your radio.
