T MOTOR AIR GEAR 355 Quadcopter/Multi-rotor Power System Kit

Description

Core Overview

The Air Gear 355 Quick-Release Edition is a new generation of lightweight folding power system designed for educational, racing, and light multi-rotor applications. It adopts a quick-release, foolproof structural design, integrating the AIR2213 KV1000 motor, the new version AIR 20A 4-in-1 ESC, and MF9545 quick-release propellers. This optimization achieves a significant overall kit weight reduction of 13% (to 280g) and a 3% improvement in efficiency. At 16V, the single-axis maximum thrust reaches 1202g, providing a reliable, ready-to-use, and balanced power solution for 4-axis, 6-axis, and 8-axis (non-coaxial) drones, making it particularly suitable for scenarios pursuing rapid deployment and high thrust-to-weight ratios.

Core Technology Advantages

Significant Weight Reduction and Efficiency Improvement

13% Weight Reduction: Optimized structural design reduces the weight of the entire power system (motor+propeller+ESC) from 324g to 280g, effectively improving the overall thrust-to-weight ratio and maneuverability.

3% Efficiency Improvement: The new AIR 20A 4-in-1 ESC combined with optimized matching brings overall energy efficiency gains, resulting in longer endurance under the same conditions.

Innovative Quick-Release, Foolproof Design

Convenient Assembly/Disassembly: The motor and propeller feature a quick-release structure combined with clear foolproof markings, enabling second-level assembly/disassembly, greatly simplifying maintenance, transportation, and replacement procedures.

Integrated Wiring: The 4-in-1 ESC significantly reduces the number of connections to the flight controller, resulting in a cleaner internal cabin, reducing installation complexity and potential failure points.

Excellent Comprehensive Performance

Powerful Thrust: At 16V, the single-axis maximum thrust reaches 1202g, providing ample power reserve.

High-Efficiency Range: According to the “Efficiency-Thrust” curve, system efficiency remains at a high level within the 400gf-800gf thrust range, making it an ideal hover and cruise operating point.

Usage Recommendations

• Pay High Attention to Installation Safety: Due to different frame base thicknesses, the kit does not provide mounting screws. You must choose screws of appropriate length based on the thickness of your frame’s motor mount plate. Ensure the threaded part of the screw does not protrude more than 4mm from the base (motor threaded hole depth is 3mm). Screws that are too long and touch the coils will cause a short circuit and burn the motor!
• Strictly Adhere to Weight Recommendations: The recommended single-axis thrust is 0.4~0.5kg. Please strictly follow the following maximum takeoff weight limits for the entire aircraft to ensure safety and performance:
  • 4-axis: 1.6~2.0 kg
  • 6-axis: 2.4~3.0 kg
  • 8-axis: 3.2~4.0 kg (non-coaxial configuration)
• Optimal Voltage Platform: It is recommended to use 3~4S (12.6V-16V) Lithium Polymer batteries for optimal performance. Test data is measured on a ~16V platform.
• Refer to Performance Curves: When designing the total aircraft weight, refer to the efficiency curve and try to set the common hover thrust within the 400gf-800gf high-efficiency range to optimize endurance.

Frequently Asked Questions (FAQ)

Q: What is the Air Gear 355 Quick-Release Edition suitable for?

A: This kit is designed for scenarios requiring rapid deployment and convenient maintenance, such as multi-rotor education in schools, racing drones, and DIY for light reconnaissance or payload drones. Its quick-release design and lightweight characteristics are particularly suitable for applications requiring frequent transportation, replacement, or debugging.

Q: The “Efficiency (gf/W)” in the test data is very high. How can I achieve better endurance in actual flight?

A: Observing the test data, at a thrust of 455gf (approximately 50% throttle), the efficiency is 10.50 gf/W, which is within the high peak range. It is recommended to set the hover weight of your multi-rotor drone to a single-axis thrust of around 400-600gf (corresponding to a 4-axis aircraft total weight of 1.6-2.4kg). This way, during hover, the motors will operate in the high-efficiency range, resulting in longer flight time.

Q: If I want to assemble a 6-axis drone with this kit, what is the maximum payload it can carry?

A: According to the solution recommendations, the maximum takeoff weight for a 6-axis configuration is 2.4~3.0 kg. This weight includes the sum of the frame, all electronic equipment, battery, and payload. During design, it is recommended to control the target weight below 2.7kg to retain sufficient power redundancy for climbing or maneuvering and to ensure flight safety.
