I have bought the excellent Foxbot dec set, and also contacted Aleksandar "The Foxbot" Pavlygin about this machine.
He gave me this link with a couple more photos of this unit:
http://ava.org.ru/iap/900.htmIf we assume that the third pic (with the spiral) is of the same aircraft as the above two, then it is indeed a "-9M".
But this could be risky guesswork if a photo of the entire aircraft of Golovachev shows up one day.
But how insane it would look if (on top of "pik-as" emblem + lightning + white-triangle + kill marks) he also decided to add a spinner spiral?Regards,
Aleksandar
