5.2 اسمبلی کے مراحل
- ونگز منسلک کریں: Securely attach the upper and lower wings to the fuselage using the provided hardware. Ensure all connections are firm.
- لینڈنگ گیئر انسٹال کریں: Attach the landing gear components. While the model can be hand-launched, the landing gear provides convenience for ground takeoffs and landings.
- بیٹری کو جوڑیں: Connect your fully charged 3S 850–1000mAh LiPo flight battery to the ESC. Ensure the battery is secured within the battery compartment to maintain proper center of gravity.
- Bind Transmitter: Follow your Spektrum transmitter's instructions to bind it with the installed AR630+ receiver. This process establishes communication between your transmitter and the aircraft.
- کنٹرول سطح کی جانچ: After binding, perform a thorough check of all control surfaces (ailerons, elevator, rudder) to ensure they respond correctly and move in the appropriate direction relative to your stick inputs.
6. آپریٹنگ ہدایات
Before each flight, ensure all components are securely attached, the battery is fully charged, and control surfaces respond correctly. Always fly in an open area free from obstacles, people, and animals.
6.1 پری فلائٹ چیکس
- Verify battery charge level on both the aircraft and transmitter.
- Confirm proper binding between transmitter and receiver.
- Check all control surfaces for free movement and correct response to stick inputs.
- Ensure propeller is securely attached and free from damage.
- Perform a range check according to your transmitter's manual.
6.2 ٹیک آف
For ground takeoffs, place the aircraft on a smooth surface, align it into the wind, and gradually increase throttle. Apply slight up-elevator as speed increases to lift off. For hand launches, hold the aircraft firmly, apply full throttle, and gently toss it forward into the wind.
6.3 فلائٹ کنٹرولز
The aircraft is controlled using standard RC airplane controls:
- گلا گھونٹنا: موٹر کی رفتار اور اونچائی کو کنٹرول کرتا ہے۔
- Ailerons: Control roll (banking left/right).
- لفٹ: پچ کو کنٹرول کرتا ہے (ناک اوپر/نیچے)۔
- رڈر: جمائی کو کنٹرول کرتا ہے (ناک بائیں/دائیں)۔
6.4 لینڈنگ
Approach the landing area into the wind. Gradually reduce throttle and maintain a controlled descent using the elevator. Aim for a gentle touchdown on the landing gear. For soft landings, reduce throttle to idle just before contact.
7. Flight Modes (AS3X and SAFE Select)
The E-flite 4-Site 3D FF is equipped with a Spektrum AR630+ receiver featuring AS3X and optional-use SAFE Select technologies.
- AS3X (Artificial Stabilization - 3-aXis): This technology works behind the scenes to smooth out the effects of wind and turbulence, making the aircraft feel like it's flying on rails. It provides a more locked-in feel, enhancing precision and stability without interfering with your control inputs.
- SAFE Select: This optional technology offers flight envelope protection, making it easier to fly. When activated, SAFE Select provides:
- پچ اور بینک زاویہ کی حدیں: Prevents the aircraft from entering extreme attitudes.
- خودکار سیلف لیولنگ: Returns the aircraft to a level attitude when the control sticks are released.
8 دیکھ بھال
Regular maintenance ensures optimal performance and longevity of your aircraft.
- معائنہ: Before and after each flight, inspect the airframe, control surfaces, propeller, and landing gear for any damage, cracks, or loose connections.
- صفائی: Clean the aircraft with a soft, dry cloth. Avoid using harsh chemicals that could damage the foam material.
- بیٹری کی دیکھ بھال: Store LiPo batteries in a cool, dry place at storage voltage. Never overcharge or over-discharge batteries.
- پروپیلر کی تبدیلی: Replace damaged or unbalanced propellers immediately to prevent vibrations and potential motor damage.
- ذخیرہ: Store the aircraft in a safe place, away from direct sunlight and extreme temperatures. The original packaging or a dedicated carrying case is recommended for transport and storage.
