Inside the IJN Nagato
Class 6 Battleship
Rated 24 sec over 100
Swampworks hull built by Bryan Finster.
Bryan uses Dumas 2 3 blade props that are
sanded down to 1 ¾. The drag props are Dumas 1 ½ The rudders are set with the
center of the props. Not easy to do with the pointy stern of this ship.
Here is the side view of the
props and rudders. Bryan
has the rudders just in front of the props. The rudders are rectangular; he
could have put a little more area at the top of the rudder and taken it from
the bottom. But there might not be room for the rudder to turn under the ship.
The stern deck is screwed down.
rarely needs to get into this area this is not a bad thing. This ship has a
very low stern it needs to have a good deck seal in the stern. The turrets are
held in place with two rare earth magnets. The gun pin is also run through the
turret so the is no way for it to fall off the ship. Bryans guns are held in place with an
aluminum mount. He has the stern guns angled 15 deg off center. This is
something the pointy sterned Jap ships have done for
a while. Jeff Lide & Bryan have had some success
with it and made it popular.
Under the deck is the rudder
servo and gears. The servo is waterproofed with Corrosion X. Bryan opens the
case to let the water in and out freely. Copying this was the only way I was
able to get my water proofed servos to work. The point stern has just enough
room to get the gears for the rudders installed. Bryan uses the Traxxas
Villian Motor Mounts for his gear boxes. The water
channeling has a sharp step in it. This helps keep the water from rushing into
the stern and driving the ship under.
The guns fit in-between the
water channeling and gear boxes. The mags are bent up
and over the stern cross brace.
The bow of Bryans ship holds his custom painted bottle.
He uses a Palmer Rock the Boat regulator. The solenoids are connected to an
accumulator tank and mounted standing up. He has Cippard
barbs and couplings to the guns to easily disconnect the decks. This makes moving the ship between battles for patching and repair
much easier. At the left is an Otter Box Bryan uses for a radio box. The Otter
Box allows quick access to the inside without removing a lid that is siliconed in place. You can see the ribs are each backed
with plywood. Bryan
says that even with the ribs backed he has had ribs shot out.
On the bow cross brace Bryan has mounted test
switches for each of his guns. You can see the Deans Ultra and Micro connectors
for motors, pumps and guns. The wiring looks to be color coded but is not
twisted. It is strapped to the air lines to make it neater. The stern solenoids
are set upright just like the bow tanks and solenoids. The little black box
near the pump is an ESC (Electronic Speed Controler) This allows Bryan
to set speed in forward faster by just programming his radio. It also allows
him to gear up his motors and leave the reverse set to 100%. The higher RPMs in reverse helps the ship stop
on a dime and go backwards very fast. A big advantage or ships with out this
set up. Some people dont like the ESC because they are easy to melt down.
Here is a shot looking into the
uses a Pearce pump with a Stinger motor. You can see the battery tray. He uses
two 12 amp hour batteries. His water channeling is ¼ thick at the sides of the
ship and gets thinner towards the tray. You can see how he bends the guns up
and over the cross brace. The mags stick through
holes cut into the deck and hidden by superstructure.
The open Otter Box. Bryan has the servos,
receiver and Team Delta switches on the top of the box. This way if any water
gets in the box it is kept away from the electronics. This box is very small
and pretty neat inside.
