so this is my second low deck build but this one is very much built for coastal flying and been a stable cam platform. arms are 6mm thick and in this length the max prop size is 5.5". with the 2mm arm braces, the 3mm battery and lower plate you've got 5mm of carbon either side of the arms making this thing SUPER stiff.. which i hope translates to a nice clean airframe tuning wise. she is pretty much a full time 6s setup hence the 5.1-5.5" props but you could cut longer arms and build it as a 6" pretty easy. there is also a hero7 pod with the same kinda gps tray off the back of the camera to keep it nice and clear of RF noise and like my lowride design it uses a nice clean split stack arrangement with thoughs to wire routing and cap placement.
