Hmm might be easier for the Vc (non-trop) to take the IXc model and create a new FM, and for a trop Vb, take the seafire, get rid of the arrestor hook and make a new FM.

You're the expert, so what ever you think will work. It's fine with me.

The problem is the filter, none of the Spits coming with PF (Vc - VIII - Seafire) have the early air intake of Channel Spits Vb's

Maybe I'm missing something (not an unusual occurrence), I was thinking that to convert a Vb to the Vc (non trop) the only visual changes would be the windshield and the cannon stubs on the wings? It seems like the FM between the two would be very similar.
