I think its probably time to conclude this blog as I've been sailing ID with the new gunnery system for some time and the system seems to be completely reliable and effective so maybe some reflections:
- The system works and I consistently get in the region of 300 to 350 shots so 65 to 70 salvos
- The PTC Thermistors and heat exchange design has proven totally reliable. I could possibly improve this by having the fog fluid injected at 90 degrees as it would be structurally easier within the turret.
- The pump design has proved to be ideal and again is entirely consistent and reliable
The Turnigy 9XR transmitter has proved ideal with both servo throw and speed adjustments. In particular controlling the forward and aft sets of turrets with two of the pots has proved ideal.
- Turning the turrets with servo sized sail winches using fishing line to pull them round has proved reliable and effective.
- Self centring is a little erratic but because I can adjust each turret set independently this is not a problem and on the water all is fine
- Early teething troubles were with ancillary components, pipes and servos and the fundamental design and concept has proved sound.
- The heat effect on the turrets was greater than anticipated. I used a plywood frame covered in plastic card using evostick and the evostick gives way with the heat causing some delamination. I have now replaced the sides with ply so this should solve the problem. The turrets were never that hot but just enough to cause adhesion problems which could not have been anticipated. Fibre glass turrets would be ideal.
- Overall I'm very pleased with the effect on the water
The bright LED's in adjacent gun barrels work okay but is probably not worth the extra effort
- Maybe I should add a sound module?
Cheers

One final question, what do I build next?
