I don't know where you fish but I imaging you make a flying maggot the same way wherever you fish. Set up your normal rig but don't put a fly on the end, just put on a bare hook with a couple of maggots on the end. I do't know how good it is for salmon, but it sure is effective for brownies and sea-trout, especially at dusk on those balmy late season nights.
Jealous of someone who's decided that they want to go home smelling of maggotts...yes I probably am.....but then I caught a wild brownie just over a pound and a half on saturday morning using an alley shrimp double salmon fly, 12lb leader on a 9 weight rod.
I was pleased to catch it, I'm easily pleased apparently, but no one was jealous..........until you work out how to catch salmon on maggot round my way, no one will be interested (by the way, David Moir who was a member of AN did once catch one cleanly on maggot, in november, when fishing for perch, (honest, i was there when he landed it) but all subsequent attempts have failed.............shrimps however are far more use)
I never go home smelling of maggots, I put them on a hook, I don't smear them all over like Brut
