ImpulseRC Micro Apex 4" Frame Kit – Powerful FPV Frame for Racing and Freestyle

The ImpulseRC Micro Apex 4" Frame Kit distills the acclaimed quality of the full-size Apex into a compact 4-inch format, perfect for FPV pilots building a sub-250g long-range drone or a high-powered freestyle quad. Featuring an 8 mm carbon fiber core, compressed X-geometry, and innovations like integrated camera tilt, split main plate, and custom shoulder bolts, this frame delivers unmatched stiffness and flight performance. The 4-inch arms support larger props for increased thrust, while the 1-year crash damage warranty for carbon and metal parts ensures confidence in demanding flights.

User reviews (e.g., NewBeeDrone) praise its intuitive assembly, though some suggest a manual would help. It’s perfect for FPV racing, freestyle, or long-range in harsh environments.
