Arrows Avanti 50mm EDF PNP Complete Assembly & Setup Guide

Important: This is a PNP version. EDF motor, ESC, all servos are pre-installed inside airframe. You need: 4-channel radio transmitter + receiver, 3S 1300mAh LiPo battery, foam-safe CA glue.

If you have the Vector stabilized version, extra gyro calibration steps are included at the end.

1. Pre-Assembly Inspection

1. Unpack all parts: Fuselage, main wing, horizontal stabilizer, small hardware bag (clevises, KA2.0��12mm screws).
2. Visually check:
   • 50mm 11-blade EDF fan inside fuselage (no cracks)
   • All 3 servos (ailerons + elevator) pre-wired
   • No damaged foam, loose wires
3. Prepare foam-safe cyanoacrylate (CA glue). Normal CA will melt EPP foam!

2. Install Horizontal Stabilizer (Tailplane)

1. Locate the slot at rear fuselage for horizontal stab.
2. Apply thin foam-safe glue evenly on the mating surface of stabilizer.
3. Slide horizontal stabilizer fully into fuselage slot; keep it perfectly level and centered.
4. Wipe away squeezed glue immediately. Leave to cure fully (30+ minutes).
5. After glue cures: Connect elevator pushrod clevis onto elevator control horn.
   • First set your transmitter throttle/sticks to neutral before attaching clevis!

3. Main Wing Installation

1. Feed the two aileron servo wires from the wing root through the opening into fuselage cavity.
2. Seat the main wing firmly onto the fuselage saddle.
3. Secure wing with four supplied KA2.0��12mm screws from underneath the fuselage. Do not over-tighten to avoid stripping foam.
4. Inside fuselage: Plug the two aileron servo leads into the factory Y-harness.

Double-check wires are not pinched between wing and fuselage.

4. Radio Wiring (PNP Core Step)

• If you own Vector Gyro PNP model: Connect CH5 (AUX) for gyro mode switch.
• Tuck all loose wiring neatly into the rear cavity of battery compartment; avoid pinching when closing hatch.

5. Battery Recommendation & Installation

1. Attach hook-and-loop tape to your LiPo battery.
2. Slide battery into fuselage; use built-in elastic strap to secure firmly.
3. Slide battery forward/backward to adjust CG (Center of Gravity).
   ? CG Reference: 60�C65 mm back from leading edge of wing root (critical for stable flight).

6. Control Surface Setup & Recommended Throws

1. Check all control surfaces move freely, no binding.
2. Verify direction:
   • Right stick right �� right aileron up, left aileron down
   • Right stick back �� elevator moves up
3. Reverse channels in your radio if surfaces move backwards.

7. ESC Arm & EDF Test Procedure (Safety First!)

1. Transmitter throttle stick all the way LOW.
2. Connect LiPo battery. Listen for ESC beep sequence:
   • 3 beeps = ESC detects 3S battery �� ESC armed.
3. Slowly advance throttle briefly to test EDF rotation.

If fan spins backwards: Swap any two of the three motor wires inside fuselage.

ESC brake is factory OFF; keep brake disabled for EDF jets.

8. Pre-Flight Full Checklist

1. Transmitter powered on, throttle at minimum.
2. All control surfaces respond correctly, no binding.
3. Wing screws tight, horizontal stabilizer fully cured.
4. Battery secured, CG verified.
5. Check all wiring is clear of EDF intake (no loose wires can be sucked into fan).
6. Do a range test for your radio system.

Extra: Vector Stabilization Gyro Version Calibration

1. Transmitter ON, plane placed on completely flat level ground.
2. Throttle down, plug battery in.
3. Wait 5�C8 seconds for gyro auto-calibration. Do NOT touch aircraft during calibration.
4. Assign a switch on your radio to CH5 (AUX1) to toggle gyro OFF / Medium gain / High gain.
5. Test gyro reaction: Tilt plane; control surfaces should oppose movement. If reversed, adjust gyro direction in radio settings.

Critical Safety Tips

• This jet is hand-launch only (no landing gear). Belly land on grass.
• Never run EDF fan without battery secured outdoors; intake is extremely dangerous.
• Only use 3S LiPo; 4S will overheat the stock 30A ESC and motor.
• Do maiden flight with low rates and light wind (<10km/h).
