Replacement Arm for AOS 5 EVO

Spare Arms for the AOS 5 V2

The AOS 5 V2 uses a topology optimized truss design for the arms. This truss design provides enormous torsional stiffness, resolving a key source of vibration in traditional frames. It also allows two particularly harmful resonant modes to be individually modified to separate them in frequency.

Truss structures are inherently very strong as they convert bending loads into compression and tension in the individual members. Carbon is much stronger in pure tension and compression than in bending. The 3 screw motor mounting reduces weight and removes the motor hole that can be a stress riser for compressive failure in hard crashes.

Y-shaped motor protectors minimize the risk of damage to those expensive components. Should you ever need to replace an arm, there are only two screws to undo and neither are shared with your electronics.
