FlyFishRC FIFTY5 Freestyle FPV Frame - O4 Pro

FlyFishRC FIFTY5 Freestyle FPV Frame - O4 Pro

The FlyFishRC FIFTY5 is a premium 5.5-inch freestyle FPV frame designed for pilots who want the perfect balance of agility, strength, and easy building. Crafted with precision, this frame combines high-grade T700 carbon fiber with signature CNC-machined metal camera side plates for outstanding durability and a clean, premium finish.

Built around the idea of keeping things lightweight, simple, and tough, the FIFTY5 bridges the gap between traditional 5-inch and 6-inch platforms. You get the nimble, responsive feel freestyle pilots love, with the extra presence, battery flexibility, and carrying capability normally associated with larger builds.

Originally optimized for 5.5-inch propellers, the FIFTY5 also supports standard 5-inch props, giving you more freedom when choosing your setup. Whether you are building for smooth cinematic cruising, fast lines, or hard freestyle sessions, this frame is ready for it.

At just 127.7 g including essential TPU parts, the FIFTY5 stays impressively light without sacrificing structural integrity. The 5 mm arms, beveled carbon edges, and thoughtfully engineered layout make assembly straightforward while keeping the frame rigid and dependable in the air.

It also comes equipped with the accessories needed for both analog and HD builds, plus high-strength 12.9-grade hardware with pre-applied Loctite for added reliability and a more secure build experience.
