I don ' t know what ' s going on . I ' m not even the official Iceberg shipper of this sub . <| sep |> True . I still imagine if there was enough room for them to hide three there for the triwizard tournament that there must be some space for it . <| sep |> Is that plywood ? I bet that ' s easily half the weight of carbon . The way most quad frames are designed is mainly to make them cheap to manufacture from sheet CF , but structurally they ' re not very clever . If you ' re building from wood , you can use glues that are as strong as the wood , which gives you more options . Wood is lighter that CF but not as strong , so you should use thicker sections and avoid stress concentrations like those standoffs a glued plywood panel would be much stronger , and lighterIMHO , a solid frame like the would be more appropriate . You could cut the layers and glue them together .
