A labour of love Geoff but will be worth it
Your A & B turrets, as will the X & Y turrets all have as you say have the 180 degrees pointing zone and firing zones, however the
Q turret whilst having the same pointing zone would have very limited
firing zones...would the latter be say +45 degrees to +180 degrees? to either port or stdb?
I have 3 x ACTion P96 servomorphs..[for different uses] and understand their speed & travel sensitivity.
So if you were training your X & Y turrets at any arc lower that ~~45 degrees the Q turret would be facing at the aft superstructure
Or, .....just thinking, Q turret could have train & fire arcs of +45 degrees from athwart ships on both the port& stdb side ....just like the real vessel
Just an observation..... as you say....."
but the main item outstanding is the gunfire simulation"
Looking forward to seeing more images as you progress.... Derek
