The Gemfan Stack Saver 2.5x18CM is designed to give reliable, secure and vibration-resistant reinforcement for an FPV drone's electronics stack. It holds a flight controller, ESC or VTX stack in a stable position, which reduces movement during aggressive flying, hard landings or crashes.
The listing says it is made of high-quality, durable material that keeps the stack firmly compressed and aligned, which prevents loose connections and lowers stress on solder joints.
An 18cm length and 2.5cm width make it suitable for many builds, from 3-inch cinewhoops to powerful 5-inch freestyle quads, and it is lightweight and easy to install.
Designed for FPV stacks: protects flight controller, ESC and VTX stacks.
Durable, strong material: made to survive crashes.
Anti-slip stability: keeps the stack firmly in place.
2.5 x 18cm size: suits 3-inch cinewhoops to 5-inch freestyle quads.
Lightweight and easy to install: adds little weight.
Longer component life: reduces stress on connections and solder joints.
An FPV stack is a tower of boards held by long screws or standoffs. Crashes and vibration can loosen the boards, let the pin headers work free or put a lot of load on soldered joints. A strap around the stack keeps the layers compressed against each other and stops them from flexing or shifting.
Wrap the strap around the stack so that it does not cover connectors that you need to reach or block airflow to hot parts such as the ESC. Keep it snug but not so tight that it bends the boards.
A tidy, well-built airframe flies better and lasts longer. Check every screw after the first few flights, use thread-locking compound on metal fasteners, keep wires away from moving parts and inspect the frame and accessories for cracks after any crash. Small parts like these are cheap compared with the electronics they protect, so replace them as soon as they wear out.

The strap is 2.5cm wide and 18cm long and is a Gemfan product (part number WL-08-1). The listing does not give the material name, so check the strap for compatibility with your stack height.
Make sure the boards are seated properly before you fit the strap, since it will hold them in whatever position they are in.
