Overview
When flight time is your #1 priority, you need the 3508 380KV. This "pancake" style motor features a flat design with a large diameter stator, producing massive torque at low RPMs. It is the gold standard for building endurance quadcopters and hexacopters (like Tarot 650/680/690 frames).
Key Features
- Extreme Efficiency: Optimized for 4S-6S LiPo setups to deliver flight times of 20–30+ minutes (depending on payload).
- Disc Design: The flat profile and open casing allow for superior heat dissipation, keeping the motor cool even under heavy loads.
- Smooth Operation: Precision balanced for minimal vibration, ensuring stable footage for aerial photography gimbals.
- High Compatibility: Comes with a standard prop adapter, compatible with most carbon fiber and folding propellers (12" – 15").
