4. Monteringsvejledning
The BETAFPV Air65 II frame is designed for DIY assembly. Follow these general guidelines for integrating your components.
- Motorinstallation: Secure your chosen 07xx or 08xx series brushless motors to the frame's motor mounting points using M1.4 screws. Ensure the motors are oriented correctly and the wires are routed safely. The frame features retained motor fixed slots for precise alignment.
- Flight Controller Mounting: Mount your 25.5x25.5mm flight controller (e.g., Matrix 1S FC) onto the designated mounting holes. The enlarged 1.2mm FC holes are compatible with 1.4mm screws. Ensure the FC is securely fastened but avoid overtightening to prevent damage to the frame posts.
- Propelmontering: Attach 31mm/1219S propellers to your motors. Ensure they are installed in the correct direction for proper thrust generation.
- Batteriintegration: The frame includes a battery slot sized 11.4x6.2mm, suitable for 1S batteries like LAVA 1S 260mAh or 300mAh. Secure the battery firmly to prevent movement during flight.
- Montering af baldakin: If using a canopy (e.g., Air Canopy, Canopy for Micro Camera 2022), attach it to protect your camera and electronics.
Vigtig: Always perform a thorough pre-flight check after assembly to ensure all components are securely attached and functioning correctly.

6. Vedligeholdelse
Regular maintenance ensures the longevity and optimal performance of your Air65 II frame.
- Inspektion: Periodically inspect the frame for any signs of cracks, stress marks, or deformation, especially after crashes.
- Rensning: Clean the frame regularly to remove dirt, dust, and debris that can accumulate and affect component performance or add unnecessary weight. Use a soft brush or compressed air.
- Fastgørelseskontrol: Ensure all screws (motor, FC, canopy) are securely tightened. Avoid overtightening, which can strip threads or damage the frame material.
- Komponentintegritet: Verify that all mounted components (motors, FC, battery) are still firmly attached and not loose.
7. Fejlfinding
This section addresses common issues related to the Air65 II frame.
- Frame Cracks/Damage:
- Symptom: Visible cracks, broken arm braces, or deformed ducts.
- Løsning: The frame is made from resilient PP material, but severe impacts can cause damage. Replace damaged frames promptly to maintain flight integrity and safety.
- Løse komponenter:
- Symptom: Motors or flight controller feel loose or shift during flight.
- Løsning: Re-tighten mounting screws. Ensure screws are appropriate for the mounting holes (e.g., 1.4mm screws for 1.2mm FC holes). Apply a small amount of thread-locker if components frequently loosen, but use sparingly and carefully.
- Overdreven vibration:
- Symptom: Unstable flight, blurry FPV feed, or unusual motor noise.
- Løsning: Check for bent propellers and replace if necessary. Ensure motors are securely mounted and free of debris. Verify that the flight controller is properly isolated from vibrations. The Air65 II frame's design helps reduce vibration, but external factors can still contribute.
