This is my first real attempt at a scratch build.
Dual engine sound generators are the blob under the bow, top shelf, as rpm increases so does the volume until at WOT the engines are singing back and forth slowly.
Under it are the 8 big GM car speakers.
Next to them is the 120 watt dual channel amplifier. Next are spare speakers.
Size 24 deep cycle battery----Novak Reversing Super Rooster ESC.---Min Kota 41# thrust trolling motor driving a 1 to 1.5 stepup timing belt and pulley setup to the 2 shafts.

2---SS 1/4" shafts supported by 5 inner bearings and 2 flanged end ones to stop prop movement.
Prop Shop 4.5" X 5.0" X 5 bladed props---2.

2 roll off fish and 2 steel tube fish. Working on electrics of a 2.1" diameter torpedo is easy.

15 USN crew and 6 Australian rangers.

4--37 mm cannons-------6--twin 50 cal. in safe storage--------This is a "Gunboat" version.

Rudders are controlled by the largest sailboat sized servo.

LWL is 90# planes in 20' to 40' at WOT takeoff.

It is built completly of 1/8" Birch plywood as I never thought I would finish her.

Coming out of a turn and accelerating to WOT straight at me stands all the hair up on me.
The engines start to sing back and forth as they are almost synched. Have to hear it, to feel it.

Where do I enlist for this boat duty ?
