Siren F5

Siren F5 is a 5" freestyle frame that focuses on a lightweight and compatibility body. It has a better thrust-to-weight ratio, making the thrust response more agile during intense flight.

At the initial design, we considered putting the largest blade in the smallest wheelbase that is only 233mm. When installed with 4.9-5.1” props, it can ensure the spacing between props makes it more efficient and more control flexible, the maximum amount even can install 5.5” props. We also ensure the largest equipment installation space at the rear of the frame, it can almost install all Vtx on the market.

In the meantime, we use the C-Lock structure which is our most advanced design. You can easily replace the arm by removing only one bolt. It also increases the strength of the frame and makes it easier to tune.

In addition, with QUADMULA PS-3 profiled spacer, the GoPro mount can be fixed more firmly on the top plate. you no longer have to worry about the tightness of screws or crushing the TPU.

SF5 uses a one-piece main plate design, with all 25mm height columns. It allows ample space in the body making installation and maintenance easier.
