How to assembly freewing f-22 raptor v2 90mm jet step by step

Pre?Assembly Preparation

1. Check all parts

• Required extra gear (not included for PNP): 7+?channel radio transmitter + receiver, 6S 22.2V 5000�C5500?mAh 35C+ Li?Po battery, heat?shrink tape, threadlocker (low?strength blue Loctite for metal screws).
• Tools: Phillips screwdriver, needle?nose pliers, hobby knife, zip?ties, cyanoacrylate (CA glue) for carbon?tube plastic inserts.

2. Pre?caution

Step 1: Install Vertical Stabilizers (Rudders)

1. Route the vertical?tail LED formation?light wiring down through the root hole of each vertical fin before mounting.
2. Seat each vertical stabilizer onto the rear fuselage mounting posts, align the pre?drilled mounting holes.
3. Secure using 4 �� KA3��10?mm machine screws (2 screws per vertical tail).
4. Plug the vertical?tail LED wiring connectors into the main fuselage LED harness; tuck excess wire inside fuselage cavities and fasten with zip?ties.

Step 2: Mount Full?Moving Horizontal Stabilators (Elevators)

1. Slide the metal pivot shaft through the horizontal?stabilator root bushing; slip the metal retaining ring onto the pivot shaft.
2. Insert the pivot shaft assembly into the fuselage rear tail bay, fit washers between stabilator and fuselage.
3. Fasten the pivot?shaft end using 2 �� PM2��4?mm locking screws, then secure the horizontal?tail mounting brackets with 4 �� PT3��10?mm screws.
4. Attach the elevator servo ball?link pushrod to the horizontal?stabilator control horn; adjust pushrod length so elevators sit perfectly neutral (level) at radio 0?trim position.

Step 3: Install Main Wings (V2 Quick?Release Screw?Free System, Core V2 Upgrade)

1. Glue the tapered plastic cone inserts onto both ends of the two ?10��650?mm carbon?fiber spars using CA glue; let the adhesive fully cure (15�C20?min).
2. Retract the landing gear fully. Slide the two carbon spars horizontally through the central fuselage spar tunnel, centered evenly left?to?right.
3. Unlock the four wing?lock switches on the lower fuselage: press each switch all the way down then release; the tabs pop upward into the unlocked position.
4. Unplug the wing ribbon?data cable from the fuselage?side connector, reconnect it to the matching connector inside the left main?wing root cavity; repeat for the right?wing ribbon cable.
5. Align the wing root openings over the protruding carbon spars, push each main wing fully inward flush against the fuselage.
6. Press down the four quick?release locking switches until they click and stay locked (they cannot pop back up when correctly engaged). Tug the wings firmly to confirm they are secured and cannot pull free.
7. Connect wing?tip navigation?light wiring from each wing to the main LED harness inside the fuselage.
8. Hook up aileron and flap pushrod ball?links to the wing?mounted servo control horns; set aileron and flap neutral positions with radio trim centered.

Step 4: Route & Organize Internal Wiring

1. Run all servo leads, landing?gear controller wire, full?LED harness (fuselage, wings, vertical?tail lights), and ESC power?signal wire back to the central battery/receiver compartment under the cockpit canopy.
2. Bundle all loose wires with zip?ties, secure them to pre?molded fuselage anchor points, keep wiring clear of the 90?mm EDF fan wheel and retract mechanical components to avoid binding.
3. Plug all servos, landing?gear control unit, and LED?controller into your 7+?channel receiver; plug the ESC signal lead into the throttle channel.
4. (Optional) If using a flight?stabilizer gyro (e.g., Aura, Cortex), integrate it between receiver and servo leads following gyro instructions.

Step 5: Install Nose Cone, Cockpit Canopy & Scale Foam Parts

1. Attach the magnet?based nose cone: align the embedded magnets on the nose cone with matching magnets on the nose fuselage; the cone clicks on and stays secured for flight, removable for battery swaps.
2. Fit the plastic cockpit canopy over the cockpit opening; snap?fit or use thin double?sided tape if loose.
3. Mount the small scale foam?detail pieces (air?intake fairings, exhaust?surround foam parts A/B/C) to the rear fuselage using thin CA or double?sided foam?safe tape, do not block the 90?mm EDF exhaust outlet.

Step 6: Linkage Adjustment (Control?Surface Travel Settings)

1. Ailerons: ��20?mm deflection at trailing edge
2. Elevators: ��20?mm deflection at trailing?edge; add 2?mm up?elevator mix when deploying full flaps to prevent nose?down pitch?droop on landing
3. Rudder: ��20?mm deflection
4. Flaps: 30?mm downward full?flap travel for landing configuration
   Double?check all control?surface directions:

• Right transmitter stick �� right aileron dips
• Pull elevator stick back �� elevator tilts upward
• Left rudder stick �� tail rudder swings left
• Flap switch activated downward �� flaps drop down.
  Reverse any incorrect servo?direction in your radio menu.

Step 7: Balance the Aircraft (Set Correct CG?Center of Gravity, Critical for Maiden Flight)

1. The official CG for the F?22 V2 90?mm is 150?mm back from the wing?root leading edge (marked on the bottom of the V2 main wing) Freewing Model .
2. Install your fully?weighted flight Li?Po battery inside the forward battery bay, slide the battery forward/aft until the jet balances level (nose and tail sit horizontal when lifted at the CG point).
3. Secure the Li?Po battery firmly with hook?and?loop straps inside the battery hatch; battery shifting mid?flight will ruin balance and cause crashes.

If the nose sits too heavy, shift the battery rearward; if the tail dips, move the battery forward.

Step 8: Pre?Flight Full System Test (Before First Flight)

1. Plug in the 6S Li?Po battery (connect ESC power lead last to avoid spark?damage to electronics).
2. Power on your radio transmitter first, then the aircraft receiver (always follow this order to prevent runaway EDF).
3. Test:
   • All control?surfaces move correctly with proper travel
   • Retractable landing?gear fully extends/retracts with assigned radio switch
   • All navigation, formation, and taxi LED lights activate
   • Throttle operates the 90?mm EDF fan smoothly; test thrust?reverse (on the 120A ESC) if fitted
4. Check for binding in pushrods, loose screws, or pinched wires. Secure any loose components before the maiden flight.
