AOS UL5 EVO

The AOS UL5 is an ultralight 5 inch frame optimized for 2-blade props. Experience the feel of a toothpick combined with the dynamic power of a full-sized 5".

Key Features

Arms

The AOS UL5 uses a truss design with a stabilising strut supporting the middle of the arm. This truss design provides enormous torsional stiffness, resolving a key source of vibration in traditional ultralight 5" frames.

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 frame features motor protector features on the end of each arm to minimize the risk of damage to those expensive components. Should you ever need to replace an arm, there are only two screws to undo making arm replacement easy.

Arms

Top and Bottom Plates

Both of these plates are 1.5mm thick to provide an optimal balance between strength, stiffness and weight.

There are mountings for up to two 25.5 or 20mm stacks with one in the front of the frame and one in the back.

Top and Bottom Plates

Camera Protection

Carbon camera plates are stiff, strong and light while being cheap to replace if they are damaged.

The camera plates include 2 standoffs to maximise durability and a cutout pattern that supports DJI O3 and all typical19-20mm FPV cameras.
