Do you think the Embraer ALX and Pilatus PC-21 look like a
Piper PA48 Enforcer (only with nose gear and yes - I know
it's not really a Mustang)? If something like 4 x 20 mm is
enough, it seems that configuration works well. If you
want something like a Oerlikon KCA, GAU-8 or even Oerlikon
35/1000 a pusher prop might be indicated.
