?? Critical Safety Rule: Do NOT mount propeller until radio binding & servo test complete to avoid injury.

1. Pre-Assembly Check

1. Unpack all foam parts, inspect for shipping cracks; repair small EPO damage with medium CA foam-safe glue.
2. Sort hardware: screws, carbon wing joiners (LONG carbon joiner = flight use; short orange plastic joiner ONLY for transport storage �� NEVER fly with it!), spinner, 4-blade prop, drop tanks, pylons.
3. Prepare tools: Phillips screwdriver, foam-safe CA, tape, balance ruler for CG, pliers.
4. Required separate items: 6S LiPo battery, 6+ channel transmitter/receiver, battery charger.

2. Tail Assembly (Vertical Fin + Horizontal Stabilizers)

1. Route the rudder servo wire from fuselage rear opening forward into electronics bay.
2. Slide vertical stabilizer fin into the rear fuselage slot; align perfectly vertical. Secure from below fuselage using supplied M3 screws.
3. Insert horizontal stabilizer tube through vertical fin holes; mount left & right horizontal stabilizers onto the tube.
4. Connect elevator pushrod clevis to elevator control horn; center elevator surface.
5. Double-check alignment: horizontal tails must be level; vertical fin perfectly perpendicular to horizontal stabilizers.

3. Main Wing Installation (Quick-Release Auto-Connect System)

1. Insert long carbon fiber wing joiner tube fully through fuselage wing saddle.
2. Push the wing wiring auto-plugs out from fuselage sockets. Match left/right wing connectors and plug firmly.
3. Slide left wing onto carbon joiner, seat fully against fuselage; repeat right wing.
4. Press down the quick-lock buttons on both sides, release �� buttons pop upward = locked. Pull wings gently to confirm they cannot slide out.

Tip: If you used CA glue on alignment cones, wait fully cured before fitting wings.

5. Optional: Mount drop tank pylons underneath wings with glue; attach scale drop tanks.

4. Canopy & Cockpit

1. Fit pilot figure (if included) inside cockpit opening.
2. Slide clear canopy onto fuselage rear locating lugs first, then lower front into position.
3. The canopy is retained by built-in elastic band; test secure fit. Avoid over-gluing canopy (removal needed for battery access).

5. Nose, Spinner & Propeller (Do LAST before test run!)

1. Fit cowling onto fuselage nose; check no rubbing against motor mount.
2. After radio setup & servo test only:
   • Slide spinner backplate onto motor shaft
   • Mount 4-blade propeller; add washer, tighten prop nut securely
   • Clip front spinner cap into backplate

Recommend balancing the propeller for reduced vibration.

6. Electronics Setup & Radio Binding

1. Open fuselage battery hatch; locate ESC, gyro module, receiver space.
2. Install your receiver inside fuselage electronics tray. Route antenna away from ESC/motor power wires.
3. Connect wiring diagram standard channels:
   • Ailerons �� AILE
   • Elevator �� ELEV
   • Rudder �� RUD
   • Throttle �� THRO
   • Flaps �� AUX1
   • Retractable Landing Gear �� AUX2
   • Optional: Gyro gain switch �� AUX3
4. Bind receiver to your transmitter. Power the plane (NO PROP YET!).
5. Center all trims on radio first. Check all control surfaces are neutral.
6. Verify control direction:
   • Right stick right �� right aileron up
   • Pull elevator back �� elevator up
   • Rudder stick right �� rudder deflects right
7. Calibrate retract servo; test gear up/down cycling, confirm gear doors move freely without binding.
8. Gyro setup (EG01): Follow gyro manual; set gain switch on transmitter for flight tuning.

7. Center of Gravity (CG �C MOST IMPORTANT FOR SAFE FLIGHT)

1. Slide battery forward/back on the sliding battery tray to hit target CG.
2. Balance the plane upside down or upright at the CG mark. Nose slightly heavy is safer than tail-heavy.
3. If too tail-heavy: add weight to nose area; avoid excessive tail weight (makes plane unstable).

8. Pre-Flight Final Inspection Checklist

• Wings locked tight, auto-wiring plugs fully seated
• All control surfaces move full range, no binding
• Retracts cycle smoothly, doors do not jam
• Battery secured with strap; no loose internal wires
• Prop securely fitted (only after all tests)
• CG verified
• Control directions double checked
• Loose foam gaps taped if needed to reduce drag

Common Build Mistakes to Avoid

1. ? Flying with the short orange plastic wing joiner (structural failure risk)
2. ? Mount propeller before power-on servo testing
3. ? Misaligned tail leading to constant rudder trim
4. ? Incorrect CG (tail-heavy = dangerous stall tendencies)
5. ? Pinching servo wires between wing and fuselage when installing wings
6. ? Over-tightening control horn screws (strip foam)

Field Disassembly (Reverse Order)

1. Remove prop/spinner
2. Remove canopy, take out battery
3. Press wing lock buttons down to unlock; disconnect wing auto-plugs, slide wings off carbon joiner
4. Remove tail if transporting long-distance

FlightLine P-51D 1600mm �C Receiver Installation Guide

1. Locate the electronics compartment

1. Remove the canopy (held by elastic band).
2. Inside the fuselage forward section (battery bay behind motor cowl):
   You will see a small black module: EG01 Flight Stabilization Gyro
   This is the hub for all signal wiring.

Layout overview:

Battery �� ESC �� Motor

All control signals run: Receiver ? EG01 Gyro �� All servos (ailerons, elevator, rudder, flaps, retracts)

2. Wiring Ports on EG01 Gyro

• THR IN �� Receiver Throttle channel (CH3)
• AIL IN �� Receiver Aileron channel (CH1)
• ELE IN �� Receiver Elevator channel (CH2)
• RUD IN �� Receiver Rudder channel (CH4)
• AUX1 IN �� Flaps (CH5)
• AUX2 IN �� Retractable landing gear (CH6)
• AUX3 IN �� Gyro gain switch (optional, CH7)

3. Step-by-Step Receiver Installation

1. No propeller installed for all wiring/testing
2. Prepare double-sided foam servo tape / Velcro.
   Mount receiver on flat foam wall inside battery bay:
   ? Keep away from ESC, main power wires (reduce electrical interference)
   ? Do NOT stick receiver directly to bare motor/ESC
3. Route receiver antennas:
   • Spread antennas in L-shape / 90�� apart
   • Keep antennas clear of carbon tubes and battery wires
   • Do not coil antennas tightly
4. Plug servo leads from the GYRO IN header into receiver channels following the list above

4. Power supply for receiver/gyro

5. Binding your receiver

1. Insert bind plug into receiver bind channel
2. Connect flight battery to the plane (gyro + receiver power on)
3. Activate bind mode on your transmitter
4. Once bound, remove bind plug

6. Post-install wiring check

1. Turn on transmitter first (all trims centered)
2. Connect flight battery to aircraft
3. Wait 3�C5 seconds: gyro performs auto-calibration. Keep plane still during gyro startup!
4. Test all controls:
   • Ailerons, elevator, rudder direction correct
   • Flaps extend/retract
   • Landing gear cycles up and down
5. If controls reverse: Reverse servo direction on your transmitter, do NOT swap wires on gyro.

Common Mistakes to Avoid

1. Unplugging factory ��OUT�� servo wires from gyro �� loss of control
2. Mounting receiver next to ESC �� signal glitches / radio cutout
3. Moving airplane while gyro initializes �� gyro drift, constant trimming needed
4. Mixing up AUX1/AUX2: swap flaps and retracts
5. Antennas bundled together �� poor radio range

Quick tip for FlySky / FrSky / Spektrum users

2. Receiver Physical Installation Steps

1. Remove propeller first �C mandatory safety step
2. Take off canopy, access battery/electronics bay.
3. Stick receiver inside fuselage with double-sided servo foam tape
   ? Mount away from ESC and thick power wires (reduce electrical noise)
   ? Keep clear of carbon wing joiner tube
4. Antenna routing rule for Spektrum:
   • Separate two antennas at 90�� (L-shape)
   • Do not coil antennas
   • Route antennas upward toward canopy opening; avoid running parallel to battery cables

3. Spektrum Transmitter Base Programming (DX6 / DX8 / NX6 / NX8 / iX)

1. Create NEW MODEL, Model Type = ACRO (Airplane)
2. Wing Type: Standard 1 AIL / 1 FLAP (not elevon/flaperon)
3. Go into Channel Assign / Function List and confirm:
   • CH5 = Flap
   • CH6 = Gear
   • CH7 = AUX3 (Gyro Gain, if using)
4. Dual Rates starting values (Warbird recommended):
   • High Rate: 100%
   • Low Rate: 70�C75% (use Switch F)
5. Flap System setup (Switch D, 3-position):
   • Position 0: 0% (Flaps Up / Cruise)
   • Position 1: 25�C35% (Takeoff Flaps)
   • Position 2: 90�C100% (Landing Flaps)
   • Elevator Mix for flaps: +5~8% elevator up when flaps deployed (prevents nose drop)

4. Binding Procedure (Spektrum)

1. Transmitter POWER OFF
2. Insert bind plug into Bind/BATT port of your Spektrum receiver
3. Connect flight battery (6S LiPo) to plane
4. Receiver LED flashes rapidly (bind ready)
5. Hold your transmitter BIND button, turn transmitter ON
6. When receiver LED turns SOLID: binding complete
7. Disconnect flight battery �� remove bind plug

5. Power-Up & Gyro Calibration (CRITICAL!)

1. Turn Transmitter ON FIRST
2. Connect flight battery to aircraft
3. Keep the airplane completely still for 3�C5 seconds
   The EG01 gyro performs automatic calibration during this time.
   If you move the plane during startup �� gyro drift, constant trim required.
4. After calibration completes, test all controls.

6. Control Direction Check & Servo Reversing

• Open Servo Setup �� Reverse menu
  Test reference directions:
• Right stick right �� Right aileron UP
• Pull elevator back �� Elevator UP
• Rudder stick right �� Rudder deflect RIGHT
• Gear switch forward �� Gear DOWN (preferred)
• Flap switch down �� Flaps extend downwards

7. EG01 Gyro Tuning via CH7 (AUX3)

• Switch A UP = Low Gain (for fast cruising/high speed)
• Switch A DOWN = High Gain (takeoff / landing / windy conditions)

Starting gain suggestion: Low = 35%, High = 65%. Adjust during first flights.

8. Spektrum Failsafe Setting

• Throttle �� 0% (motor off)
• All other control surfaces hold neutral
  How:

1. Transmitter ON
2. Set all sticks to neutral, throttle idle
3. Connect aircraft battery, wait 10s
4. Power off transmitter for 5 seconds
5. Power transmitter back on �� failsafe saved automatically

9. Common Pitfalls (Many builders make these mistakes)

1. Moving plane while gyro calibrates �� bad drift
2. Mix up AUX1 / AUX2: flaps and landing gear swapped
3. Receiver mounted right next to ESC �� radio glitches
4. Antennas bundled together �� poor range
5. Reversing wires on EG01 gyro instead of transmitter
6. Flying without verifying CG (120 mm from wing leading edge at root)
