,
hello barry,
my becker is huge ,after all, its a stand well back scale model ,and was never intended to be anything but a quicky
almost 2 inch deep+3in. long ,becker blade approx. 1 in. long
as my paddler steers ok, this large rudder should be better , as long as the model is moving ,it will steer.
I have read ,that some german modellers have fitted a large, balenced ,fat rudder on the centre line , w 2 balenced rudders aft of the screws,and they claim this steers as well as sterable korts rudders, please note , 3 rudders, no korts.
the original ships dont have too steer like our models ,so I dont want too build a bad handling vessel
food for thought+experimentation
