Following the success of the original Hypetrain FREESTYLE motor, we are proud to release a new flagship motor, the Hypetrain ACRO. This motor features the same 2450 KV rating of the FREESTYLE which has been proven to provide for good all around power and efficiency. The stator size, however, is new. The 2207 stator size is meant to provide a sharp power curve and more top end thrust.
The bell features a revised design. It maintains the iconic tri-spoke design inspired by the Rotor Riot logo. The outer lip has been thickened to help reinforce the bell ring against denting during crash impact. This DURA-BELL design will help ensure smooth rotation even after bando bashing.
Another feature meant to improve durability is the use of multi-strand winding on the stator. Multi-strand windings are less susceptible to breakage in the event of a rough crash where the arm is broken and the motor wires get pulled. This will improve your chances of being able to reuse the stator even if the bell is damaged.
Like all Hypetrain motors, the bell is easily removable via a M2 shaft screw with a 2mm hex head to prevent stripping. Compared to a c-clip, this shaft screw facilitates serviceability and cleaning.
The “open bottom” style base allows for considerable weight reduction and improved cooling. The 16×16 mm mounting screw pattern opens up new design possibilities while still maintaining backwards compatibility with legacy frames.
