FPVDroneM2 Anti-Vibration Fixed Screws Mounting Hardware Spacer Rubber Standoffs for FPV Drone F3 F4 Mini Flight Controller(12pcs)

In theory these should be awesome, but they are too tall to really work with hardly any micro builds. You have to use a washer on top of them to tighten down enough on the flight controller, esc, and vtx stack or they just rattle around on them. Even my bigger 3” builds don’t have enough room for a 3 high stack. I always end up using a long 2mm screw, and rubber washers in between the stack.

Work well

Sent wrong size and the quality was lacking too.

There is no way to make them work. You won’t even be able to return this junk, become all will break. They deserve five negative stars

Pretty much useless

The break apart easily

This is how people used to vibration damp mount their flight controllers back when we used to ride our dinosaurs to the arcades...They work for certain applications but not for all.You do have to be careful not to over torque them.Because you'll obviously destroy them...

Will buy again.
