MAD BSC 4315 – Professional Propulsion for X-Class & Heavy-Lift UAVs
 
The MAD BSC 4315 is engineered for the extreme demands of X-Class racing and heavy-lift industrial applications. Designed to drive 13" to 15" propellers with surgical precision, this motor provides the massive torque and thermal stability required for large-scale FPV frames and professional cinema rigs.
 
Why the BSC 4315?
Massive Thrust Output: Capable of generating over 7kg of thrust per motor, providing incredible lifting power for heavy payloads and high-speed X-Class maneuvers.
Extreme Durability: Built with high-temperature resistant windings (up to 180℃) and N52H arc magnets to maintain performance under grueling continuous loads.
Cinematic Smoothness: Precision-balanced rotors ($\le$ 5mg) ensure that even on 15-inch props, your footage remains free of low-frequency vibrations.
Optimized for High Voltage: Engineered to thrive on 8S to 12S LiPo systems, offering maximum efficiency for long-endurance industrial missions.
 
Step up to giant-scale FPV with the MAD BSC 4315. Whether you're building a competitive X-Class racer or a 15" industrial quad, this motor delivers the reliability and raw power you need.
Giant Scale Ready: Optimized for 13"–15" propellers.
High Torque: 12N14P configuration for instant response on large discs.
Pro-Grade Internals: 6mm internal shaft and oversized bearings for maximum impact resistance.
