Usage Recommendations
- Strictly Adhere to Recommended Configuration: To achieve the claimed performance, please use the recommended configuration: AIR2216II KV920 motor + AIR 20A ESC + T1045 propeller, paired with a 4S (16V) battery.
-
Accurately Plan Takeoff Weight: The recommended single-axis thrust is 0.45-0.55kg. Strictly design your drone according to this recommendation and the following aircraft weight limits:
- 4-axis maximum takeoff weight: 1.8-2.2 kg
- 6-axis maximum takeoff weight: 2.7-3.3 kg
- 8-axis maximum takeoff weight: 3.6-4.4 kg (non-coaxial configuration)
- Make Good Use of Performance Curves for Optimal Design: Refer to the "Efficiency-Thrust" curve; system efficiency is higher in the thrust range of approximately 400g-800g. It is recommended to design the hover weight of the aircraft within this range to achieve optimal endurance.
- Emphasize Installation Reliability: When installing propellers, ensure the use of appropriate thread-locking compound and tighten securely to prevent loosening. Utilize the feature that motor extension wires can be cut for neat wiring, reducing interference.

Frequently Asked Questions (FAQ)
Q: What are the main advantages of the Air Gear 450 compared to the earlier Air Gear 355 or other 2216 motor kits?
A: The main advantages lie in comprehensive performance improvements: while reducing weight, it achieves a 9% increase in maximum thrust and a 4% improvement in system efficiency. Additionally, its triangular six-rib motor structure and high-toughness propellers provide better crash resistance and durability, as well as a 300-hour long lifespan, making it more suitable for high-intensity teaching and training scenarios.
Q: How to choose the appropriate number of axes (4, 6, 8) according to my project requirements (such as payload, flight time)?
A: First, determine the estimated total weight of your aircraft (including all equipment). Then refer to the "maximum takeoff weight" range in the usage recommendations to select the number of axes. For example, if the total weight is 2.5kg, a 4-axis (limit 2.2kg) is insufficient, and a 6-axis (limit 3.3kg) should be selected. Under the premise of meeting the payload, fewer axes typically consume less power, but may have lower power redundancy and safety.
Q: What does "BEC: None" mean in the ESC parameters? What do I need to prepare additionally?
A: "BEC: None" means that the ESC does not have a built-in voltage regulator module and cannot provide 5V power to the receiver. You must purchase an independent UBEC (voltage regulator module) or use a PDB (power distribution board) with BEC function to power these devices.
Q: What is the significance of "Optimal RPM Range: 6000-7000 RPM" in the propeller parameters?
A: This indicates that the T1045 propeller exhibits optimal comprehensive performance in terms of aerodynamic efficiency, vibration, and noise levels within the 6000-7000 RPM range. When designing the aircraft, you can refer to the test data to ensure the motor speed corresponding to common flight states (such as hover) falls within this range, which helps achieve longer endurance, smoother flight experience, and lower noise.
