MAD Ultima FS1303.5 5500KV FPV Freestyle Motor

The MAD Ultima FS1303.5 5500KV is a precision-engineered brushless FPV motor optimized for freestyle and micro 3-inch builds. Weighing just 7.6g and delivering up to 228.8g of maximum thrust (tested on 4S with a 3-inch propeller), it provides responsive throttle control and efficient high-RPM performance. Developed through controlled testing, it features a lightweight titanium shaft and 0.15mm high-efficiency silicon steel laminations for improved efficiency, refined balance, and durable construction. Ships from our U.S. distribution center for fast domestic delivery.

The FS series of MAD FPV brushless motors is specifically designed for freestyle flying. The development process involved six months of rigorous testing, resulting in refined aesthetics and improved functionality. The main difference between the FS and BSC series is the lightweight titanium shaft and the 0.15mm silicon steel sheet, which increases efficiency. Additionally, the product has an aesthetically pleasing appearance due to secondary anodizing.
