Yes, first plane for January FriKOTH will be the Ki-84-Ia.
Winner of the previous event picks the plane for the next event. That's the way I've don't it since I came aboard in 2005.
What gave you the idea that the Ki-84-Ia would NOT be January's first ride in FriKOTH?
On a sidenote - I guess I should just call it KOTH and not FriKOTH but I'm still delusional in thinking this event has a future.
