Hi there All
Here's some food for thought;
HMS Ajax - 4 props - all turning outboard - with electronic mixer and she spins on a sixpence without a mixer - turns, but in about 3 ships lengths using rudder only.
HMS Ajax - same ship as above - inboard turning props - makes an ideal straight runner and she refuses to turn - even with Mixer
MTB - triple prop - two outermost props turning outboard; inner prop turning ante-clockwise - no electronic mixer - but with scale rudders - turns in about 20 boat lengths - not very manouvreable
MTB - same boat as above - but reversing the outermost props to turn inboard and it is the most un-manouvreable boat - but, there is a slight increase in speed.
VOSPER 73ft RAF Rescue Launch - twin prop - outboard turning - scale rudders - dont think there is a lake big enough for her to turn in - with or without mixer or reversing the props to inboard - it makes no difference - she just persists in running in a straight line.
SEAFORTH CLANSMAN - no props and still she goes like stink hahahha seriously, two props outboard turning in fixed court nozzles; with an electronic mixer and a bow thruster, obviously when we use the bow thruster and the mixer you can get the model to do anything you like - even the Swan Lake Ballet ??? without using the electronic mixers or the bow thruster she still has a pretty turning circle
I have been told by the 'tuggies' at the Boat club - if you want manouvreability - have outboard turning props - independently controlled. If you want sheer pulling power, have them inboard but you do lose out on manouvreability.
Last but not least, RAF Whaleback - 3 props turning the same way - with electronic mixer and can control each motor independently - *horrible* useless..................lorra lorra watta arl owa the place and plenty stern shift to one side
Aye
