In some ways the airframe could be viewed as a biplane, and this is the conventional means of bracing the structure in order once again to provide the required stiffness. These are 1000 x 12 x 2mm carbon fibre strips and my only concession to the material as yet. (We've larger strips somewhere in the workshop at the flying field that can be subbed on the day). They are attached where the 6mm end-bolts secure the cross-spars at the leading and trailing edges of the panniers, with the overhangs ground off; whilst a pop-rivet connects the pair at each centre-point.
