Siren F3

Sale price$46.00

Currently estimated to be restocked in April, also can refer to Siren F35 Split

Siren F3 is a 3" 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 and cinematic shots.

At the initial design, we considered putting the structure of a 5” frame into a 3” body. Keeping the design of interchangeable arms and the sufficient space for equipment installation, Siren F3 fly much like a 5” frame but lighter and smaller. 

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(Less filter, higher PID).

In addition, with QUADMULA PS-2 and PS-3 profiled spacer, the 3D prints TPU can be fixed more firmly on the plate. you no longer have to worry about the tightness of screws or crushing the TPU.

SF3 uses a one-piece main plate design, with all 25mm height columns. It allows ample space in the body making installation and maintenance easier.
