- Emanuel Filiberto Duca d’Aosta -

 

RM Emanuel Filiberto Duca d’Aosta – Tyler

2.5 units, 22 seconds, Italian Light Cruiser

 

The Duca d’Aosta subclass consisted of two ships: Emanuel Filiberto and Eugenio Di Savoia. These ships were the fourth generation in the “Condottieri” light cruisers, which was a line of Italian light cruisers built from 1928 through 1933, each subclass serving as a stepping stone in the evolution of the line.

 

The Duca d’Aosta subclass were of interest to me due to the relatively large size for class 2, such that I thought it would be relatively easier to build than some of the smaller class 2 cruisers. Additionally, the step deck design means less hull exposure. And still another bonus, there have not been many of these ships in the history of the hobby, some of us value uniqueness. In my mind, it was going to be like an Italian version of the FN Gloire.  I first battled this ship in 2009 and have used it as my secondary ship and campaign cruiser ever since. It is set up with a ½ unit pump and twin stern guns of 50 rounds each firing together.

 

 

 

 

 

 

 My favorite feature of this ship is the access point for loading the twin stern gus. Though it is a bit cramped. The rear funnel has a post through the deck fitted with a spring on the back side which allows it to be pulled upward and swiveled 180 degrees to allow access to the load point. Also seen on this view are holes through the deck that initially had screws to hold the deck in place. I subsequently fitted the ship with slides/locks.

 

 

 

The deck sections latch in a way in which it holds itself together. The bow most section is the first off/last on and slides towards the stern to come off. The overlap of the higher superstructure containing the bridge/funnel holds down the middle part. The middle part is also held down in part by the swiveling smoke stack. I put on rotating latches where the mid section and stern deck overlap to help keep things in place. The bottle is in the far bow, then the batteries, then a modular radio box (I have 3 of these that are identical and are used in all of my cruisers). Astern to that is the pump which sits right in front of the drive motors.

 

 

 

With measurements starting in the stern. The bottle is 3.5 oz. Batteries are two 6v, 5 amp hour NiMH run in parallel for 10 amp hours.

 

 

 

With the bottle and batteries removed you can appreciate how I cut material out so the bottle and batteries to sit low in the ship.

 

 

 

The middle section. You can see the water tight simple switch-based radio box that I have made 3 copies of over the years. I have kept consistency for modular ability and simplicity. This is admittedly outdated as most ships are now running electronic speed controllers and solid state switches. In the future I expect switching over to more modern technologies which might allow for the movement of the bottle to the center compartment, which theoretically could improve turning with weight redistribution away from the extreme bow/stern and towards the center.

 

 

 

The stern portion of the ship. The tape measure is flush with the stern, but the angle makes it look off. The turret is on a hinge to adjust the O rings of the guns, this sort of locks down by swiveling the higher turret. Until I had made some adjustments, the BB’s were skipping off the deck, which is where the paint has been chipped away.

 

 

 

Th slides are somewhat visible on this view. The now not used 4-40 threaded inserts are visible in the sub deck.

 

 

 

The motors are direct drive via dog bone to 1.25 inch dual props. The solenoids and accumulations tanks with check valves sit just in front of the cannons. The ship initially had a water proof rudder box which was later changed to a water proof servo and the box was opened. I cut holes in the box so the water can flow in and out but left the structure of it in place mostly because it would be inconvenient to cut it out. The guns stick out through tiny holes that required disassembling the gun to get them out. I did this to try to limit water coming in the very low stern part of the ship, it makes working on the guns a bit annoying. Many captains will fill the holes with silicone or foam to water seal. The gun magazines are zip tied to the deck. The barrels are also zip tied to the deck.

 

 

 

Rudder and prop positions. Props are 1.25 inch (x2) Octura brand that was previously available and now discontinued. They are fairly direction and with the narrow pointy stern, this ship flies in reverse. The turning however is not very good despite the attempted fish tail rudder.
