Looking at the close-up, there appears to be enough room above the prop hub for an upright engine. Can anyone say "Fuji 4-stroke"?
But, we have to make a cooling hole above the prop hub for an upright mount.
It would be very difficult for me to choose upright or inverted.
I have Marutaka P6E balsa kit which has a cooling hole in front for upright mount,
although I can not notice any air exit hole on the plan.
