Torx T30 Countersunk Screw
M8 *40MM
They are included with the purchase of a Ronix mast or complete foil kit.
These are the same 2 screws that also mount the fuselage to any Fluid/Shift Mast.
These 2 screws are not required if you have a Shadow Carbon Veto Mast as the mast top plate and mast are already connected and don't require any additional hardware.
