Installed from the factory are super-lightweight M3 aluminum screws. They are anodized to protect against
short circuits. The provided mounting screws are made for frames up to 2mm thickness. If your frame is
thicker, please use below table to find the correct screw length:

Carbon fiber frames
Carbon fiber frames can conduct electricity, therefore the lower plastic isolator bed must be used. If you are
mounting the stack onto power distribution boards or G10 frames, you can use smaller nylon washers or
stand-offs (3mm shorter) instead of the plastic isolation bed.
Frame type:
Mounting options:
G10, other glass fiber materials
No plastic bed, mounting screws on all four corners
Carbon Fiber, FR4 with copper
Plastic bed required, mounting screws only on GND “-” corners
When using carbon fiber plates, make sure that you only screw the mounting (GND) screws through the
frame, the power-carrying screws (VBatt) remain isolated inside the plastic bed.
Make sure that no power carrying elements can get in touch with the carbon frame except ground
(Powercube GND, VTX antenna socket etc.).
Pay special attention to motor phases, also make sure the screws are not too long to push up into the motor
windings.
