The base of the Phantasm Carbon W103 mast has more location options compared to the Phantasm AL 103W. This is due to the additional mounting holes which allow the mast, and therefore the front wing location to be positioned about 4cm further back. Measurement was made using an 872 fuse (wing was a PTM 926).
I also measured the angle of the mast rake (fuse to board bottom) with a Wixey digital angle gauge, Carbon W103 was 0.90 degrees and AL 103W was 0.60; virtually the same.
