Has nyone tried this Mod? I saw in last months Model Boats an article on up dating the old "Skimmer" Model by Glynn Guest, Brushless, bigger etc. Well I have a 6 bladed Ducted Fan Unit, 66mm diameter, intended for Speed 400 Motors, I just thought that instead of the propellor which needs a guard etc, how about useing a D/F? Could place the rudder right behind it, I intend to extend this so there is some water rudder too.Be lower, more compact, will I need to extend the jet outlet to get a better effect, make a jet pipe, can that be a parrallel tube or must it be shaped? Any thoughts or ideas? I will try to take photos as I go along, but don't hold your breath!
