Extended Multirotor Endurance
I7 Quadcopter Customer Case: 124mins flight time, 10.35kg MTOW with 2kg payload / 13g/W at 2.5kg thrust per arm. I Series is purpose-built for multirotors that need to stay in longer, not just minutes, but hours.
User-Friendly Integration
Integrated Motor and ESC
Plug-and-Play
Motor and ESC are perfectly matched, ready to use out of the box
3-in-1 Integrated
Motor+Propeller+ESC, one step system
Compact size
Eliminating ESC housings reduces weight
Protected ESC
No exposed wires, fully enclosed wiring for protection
I-Series Propeller
Quick-Release
and Folding Prop
I5, I7 feature a tool-free propeller. Install or remove a blade in 2-3s with the 3-claw lock, proven over 5,000 cycles with strong ultra-light carbon fiber.
I9, I11 feature folding propellers. This space-saving solution allows your drone to fit compactly into a car for easy portable, with strong ultra-light carbon fiber
Noise Reduced Prop
Engineered for silence: only 65-67 dB at 5 meters.
Quiet enough for city airspace and gentle enough not to disturb wildlife (I7 data)
Noise reduced propeller test
Two Mounting Options
Precision-machined aluminum alloy connectors compatible with 25mm, 30mm, and 50mm carbon tubes for quick, tool-friendly installation Custom sizes are also available
The connector can be completely removed, allowing the motor to mount directly onto non-standard or custom arms, just like typical motor
Safe and Reliable Flight
10,000-Hours service life

10,000-hour life testing for core components

1,200-hour accelerated endurance test passed

1,200-hour flight cycling validation

Propeller durability detail
Integration ≠ Poor Cooling
Large vents, expanded cooling surfaces, and a thermally optimized aluminum body keep internal temperatures stable—proven by 1,200 hours of continuous working test.
Ready for it
With IP46 protection and a -30℃ to 65℃ operating range, I Series stays ready for demanding environments with dust, moisture, cold starts, and high daytime temperatures.
