Happymodel Crux35 Micro Freestyle Frame Kit

The Happymodel Crux35 frame kit gives micro-class pilots a clean, lightweight foundation for agile, confidence-inspiring freestyle. Designed around the 3.5” prop class, this frame emphasizes precise stick feel, durable plates, and tidy build routing so you can focus on lines—not compromises. Whether you’re upgrading a daily basher or planning a brand-new micro ripper, the Happymodel Crux35 frame kit keeps weight low without sacrificing the stiffness that makes split-S lines, trippy dives, and tight powerloops feel locked in.

Built for Micro Freestyle Control

Micro quads live and die by frame stiffness and geometry. The Crux35 prioritizes balanced proportions to keep the center of mass tight while maintaining prop clearance, giving you crisp authority on snap rolls and reversals. The result is predictable handling at both low and high throttle—perfect for tight parks, garages, bandos, and creative urban spots.

Lightweight, Durable Construction

A micro that flies every day needs a frame that survives every day. The Crux35 uses carbon-fiber plates paired with sensible bracing and hardware to manage impacts while holding tune. The design helps resist arm twist and soft oscillations, so your PID and filter work stays consistent across packs.

Clean Build, Protected Components

Thoughtful mounting locations and cable paths make it easier to route wires cleanly and keep the build serviceable. Camera protection and side plates help guard your lens from scuffs on sketchy landings, while the stack area provides room for common micro electronics layouts. The result is a tidy, rattle-free build you’ll enjoy maintaining.

Versatile for Your Parts Bin

Whether you’re migrating components from an older micro or selecting fresh motors and AIO/stack hardware, the frame is friendly to common micro standards. Choose your preferred camera size, VTX style, and antenna mounting; the layout accommodates typical micro components without forcing awkward compromises.

Who It’s For

Pilots who love snappy freestyle in tight spaces, want a dependable practice rig, or need a compact platform for creative filming will feel right at home here. The Crux35 makes an excellent first custom build frame and an even better daily driver.
