difference between retro'd a4 and fly???

[djroot2]

What's the difference if any between a retro'd A4 and a Fly?

I know the retro puts the fly electronics into the it but is that the only difference between the fly and a4? other than the seni holes and stuff.

Pretty much and slightly better air passage for the Fly.

And cooler milling (IMHO) on the retro. Different ribbon covers too.
