- Page 3 To avoid injury or damage to electronic speed control, Do not plug the battery into the speed control until all of the steps have been followed on page 15. The ZAGI-400 X is not a combat or bungie launch airplane. The design objectives were to make a rugged low cost, light weight, aerobatic electric flying wing.

- Page 5 Layout the bottom beds on a flat surface. Tape them together. Repeat for top beds. Align the cores together on the bottom bed. Spray the root end of the wing cores with #77 spray adhesive. Put a piece of clear wrap or wax paper between the beds and the cores to pre- vent sticking.
- Page 6 The ZAGI-400 X should be sprayed with #77 and covered with tape before any holes are cut for radio installation. This will avoid getting spray adhesive in the radio compart- ments or on the antenna. Most of the colors are transparent enough to see the servo cutout marks through the tape.
- Page 7 Taping Tip Covering the top and bottom of the wing in contrasting colors makes the plane much easier to fly. Apply the darker color on the bottom surface. An optional roll of color poly tape will be required to do this. Place weights on the wing panel opposite the side being covered.
- Page 8 (See Figure 7) Hold the elevons together and sand them until they are identical. Trim the outboard end to match the angle of the wing tip. Trim the inboard end of the elevon to match the angle of the motor cutout. Make the elevons about 1/16” shorter than the wing tip to assure the elevons don’t rub against the winglets after they are installed.
- Page 9 (See Figure 9) Trim the motor tray with scissors along the cut line. Notice that the cut line is the impression 1/2” from the side rails of the compartments. Leave the vertical lip at the rear of the motor tray. Trim the canopy along the cut line. The canopy cut lines are more visible when viewed from the inside.
- Page 10 (See Figure 10) Install the antenna along the leading edge seam between the two types of foam. Cut a 1/4” slot in the seam between the receiver (RX) and the wing tip. Push the antenna into the slot with a flat blade screwdriver. The antenna will extend several inches beyond the tip.
- Page 11 Deans Ultra connector plugs into the battery. The red and blue pair of wires should be soldered to the motor. The Zagi-400 X uses a pusher configuration which requires a reverse rotation motor. Reversing the rotation of the motor is achieved by reversing the polarity to the motor.
- Page 12 Velcro cut-out Receiver Deans plug Strain relief Speed control Red wire Blue wire Velcro cut-out Figure 13 (See Figure 13) A strain relief can be made to protect the ESC wires from damage on impact. Tether the Deans connector on the ESC to the motor wire tie with a length of dental floss.
- Page 13 (NOT THE BATTERY SLOT). The red and blue pair of wires with the spade connectors should be soldered to the motor. Zagi electric wings use a pusher con- figuration which requires a reverse rotation motor. Reversing the rotation of the motor is achieved by reversing the polarity to the motor.
- Page 14 (See Figure 14) Peel the protective paper off of the hook side of two strips of Velcro. Stick the strips to the battery 1/2 inch from each end. Press the loop side to the hook side and peel the paper. Press the battery in place with the sticky side down.
- Page 15 (See Figure 16) Punch-out and separate the two nested winglets. Punch-out the 1 1/4" x 1/4" slot in the winglet. (See Figure 17) Put a piece of fiber filament tape through the slot to the top of the wing and wrap it around to the bottom of the wing. Add two more pieces of tape to secure the winglet in place.
- Page 16 (See Figure 18) Lay the wing bottom-side-up. Tape a 1/4” dowel directly over the spar. A round pencil or ball-point pen can be used. Place the wing right-side-up on a flat surface. Balance is achieved when the wing balances momentarily on the pencil. The battery bay is longer than the battery. Move the battery forward or backward to balance.
- Page 17 First time motor power-up The following steps are provided for a safe first time motor power-up. Do not press the prop onto the motor shaft yet. Test the motor hookup before the prop is installed. Make sure that the battery is charged. The batteries are not shipped with a charge.

Page 18: First Flight
The first glide test should be done on flat land in a light breeze. The Zagi-400 X should be held by the nose with your palm up over your head and your thumb wrapped around to the top. (See figure 20) Hold the Zagi- 400 X over your head with the nose pointed straight ahead. - Page 19 Battery Life and Power Management Battery life is a determined by two main factors; charging and discharging. Both of these functions produce heat. Warm is okay, hot isn’t. A hot battery has either been charged or discharged too fast. First, charging. Make sure that the charger is designed to charge the number of cells being charged.
- Page 20 The Zagi-400 and the X are supplied with a balanced power system. Changing the prop will change the load on the ESC and the battery. The Zagi-20 ESC is rated at 20 amps continuous. The Zagi-400X with a 1700 mAh battery and the stock prop draw 12.5 amps at full throttle.
- Page 21 Throwing the Zagi-400 X Figure 21 Hold the Zagi-400 X by the nose with your palm up over your head and your thumb wrapped around to the top. The secret to this launch is the energy you exert with your fingers in the follow through.
