The basis of the power plant model boats is the electric motor power of about 60 watts running on the propeller with a diameter of 30 mm, In principle, can be mounted on the boat propulsion installation of the two less powerful engines — spark boat helps to better stay on course.
A current source are the four “AA” battery with a capacity of 1.2 A-h that allows the model to move at full speed for 12 minutes. The engine speed is regulated by a discrete two-stage switch in which the switching 10 W resistors 4.7 Ohm. However, if possible it is better to equip a power unit with electronic speed controller — these are quite often used by modelers.
Theoretical drawing of the hull (side) and the shape of the hull frames
After mounting the power unit in the housing is glued in plywood bottom of the Central compartment in which are mounted a rechargeable battery,
the lift and speed control of the motor, and a vertical plywood walls — foundations servos.
The deck is sheathed with balsa veneer with a thickness of 2 mm. While it remains a hole, repeating the form of the “combat logging”. The resulting contour of the opening is enclosed inside rails cross section 5×2 mm.
“Combat cockpit” is going on epoxy glue from the 1-mm of plywood or cardboard. Missile containers can be glued of thick drawing paper or, better yet, match them to suitable plastic tubes. Farm-base containers are collected on the glue from polystyrene rods-blanks. The mast is wooden, sensible things — polystyrene or plexiglass.
All add-ons are colored in gray (ball) color. The same color is painted and the upper part of the side, to the waterline. Below the waterline the hull has a red or green color. The bollards, capstan, chain stopper, and anchor — black .
