SIREN F5 MINI is a 5" freestyle frame that focuses on a lightweight and compact body. It has a better thrust-to-weight ratio, making the thrust response more agile.
At the initial design, we consider putting the largest blade in the smallest wheelbase only 218mm, 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 can install 5.2” props.
In the meantime, we use the C-Lock structure which is our most advanced design. You can easily replace the arm with remove only one bolt. It 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 Mini uses a one-piece main plate design, with all 25mm height columns. It allows ample space in the body making installation and maintenance easier.
