Europa initially produced the monowheel panel as a simple moulding with ply reinforcemet.
Builders found this inconvenient, as the whole panel had to be removed to access anything, and removable sub panels were developed by the Europa Club (SM10402)
Following the introduction of the Trigear a more suitable panel (without the slot for the landing gear lever) was produced by Europa. This remained a simple moulding.
About 2000 Flight Crafters produced a full width Mone panel. The cost was $575.
Following the redesign of the centre tunnel (first delivery 2011) Swift are developing a matching panel.
