Armada bonecrusher does not seem to fit on primus' minicon ports. Any other minicons in the armada series that are compatible? -thx
Bonecrushers powerlinx port is sort of all the way off into the one corner of the underside of his vehicle mode, I'm guessing that's why you can't fit him anywhere?. Unfortunately I haven't got Primus but I flipped all my Mini-cons over and took a pic, hopefully that helps show you where the figures plug into on larger figures. I hope rikkomba doesn't mind it if I flash the @rikkomba signal, they might be able to show you Primus with a lot of Mini-Cons on him.
I'm not sure where on Primus Mini-Cons can go but Dualor takes up 30mm width wise with the powerlinx port in the centre, length wise (his port isn't exactly centre) 25mm from the centre of the powerlinx port to the front of the tank and 30mm from the port to the back of the tank. Overall he takes up 30x55mm space with the powerlink spot more or less in the dead centre, the other green tank in the Destruction Team is pretty much the same dimensions and port placement too.
I thought they all did. Fun fact: The post on G1 Ultra Magnus's left forearm is Mini-con compatible. He can weild the Skyboom Shield.
