I just got my new Nitro Z21 that came with a Merc 250 4 stroke and it has a 3 blade Fury prop that has no plugs in it. The hole shot is great, haven't opened it up yet with trim up as I'm still in break-in period, only got 2 hours on it. Does anyone know the best set-up using plugs/no plugs for this particular set-up?
