Muscle Cloud / Ultimate Exceed – BJCraft’s Next-Generation F3A Biplane
BJCraft’s Muscle Cloud, known globally as the Ultimate Exceed, is the latest evolution of the legendary Ultimate Biside. While it retains the proven wing and stabilizer design of its predecessor, it features a completely re-engineered fuselage that delivers dramatically improved knife-edge performance—without sacrificing the exceptional stability, tracking, and wind-handling qualities that made the Biside a favorite among top pilots.

Tested and flown by Juan Rombaut of RombautRC with a 23x20 F&R propeller and the Dualsky Contra Rotating System, the Muscle Cloud / Ultimate Exceed offers an in-flight feel reminiscent of indoor F3P—smooth, locked-in, and precise, even in strong crosswinds. The result is unmatched control and refinement, whether performing complex rolling sequences or maintaining perfect lines in demanding schedules.
The redesigned front canopy follows the latest F3A aerodynamic trends, further enhancing performance. True to BJCraft’s reputation, setup is quick, trimming is straightforward, and stability is rock-solid through challenging maneuvers such as stall turns, spins, and snap rolls.
As Juan Rombaut describes it:
"You can see the soul of the Biside, but with a completely renewed knife-edge performance."
With modern F3A sequences incorporating more knife-edge elements than ever before, the Muscle Cloud / Ultimate Exceed is built to give expert pilots the precision and ease needed to push the limits.
Why Two Names?
Originally launched in Asia as Muscle Cloud—a name inspired by powerful, high-energy weather phenomena symbolizing force and precision in flight—the aircraft later adopted the name Ultimate Exceed for the global market. This title highlights how it goes beyond expectations, setting a new benchmark in F3A performance. Whichever name you prefer, the aircraft is identical: designed to dominate the skies with elegance, power, and absolute control.
