Orrca Qld has made a clarification to the wing rule 9.14
The rule may have caused some confusion and now reads as:
Overall Wing size Inc endplates (WxDxH) 190x40x20Max (mm)
Wings (excluding endplates) are to be of single moulded construction (no flat-packs/bend your own) and to be mounted directly to the body (no spacer between shell and wing), on the mounts provided at the back of the shell.
Orrca Qld apologise for any confusion
