With these boats, both the hull and the deck are molded and quite often will be already joined at the factory. Scale Boats Scale boats encompass just about all kinds of boating where the model is designed to look and perform like its full size counterpart. Although a few scale boats are powered by glow, gas or steam, the majority of scale boats are electric powered. Unlike the electric hydroplanes and deep vees where speed is of a concern, the scale electrics are generally powered by lower RPM, lower amperage, higher torque motors. Six or twelve volt lead acid or gel type batteries are generally used and will give long running times of from a half hour to several hours on a single charge.
Speed is controlled by either a mechanical or an electronic speed control with forward and reverse.
The radio controls the speed with one channel and the steering, via a rudder, with the other. These accessories can be powered with the same 6 or 12 volt battery that powers the motor and additional channels on the radio can be used for activating them. Devices are available that can be added to your radio system to allow several different functions to be controlled by one channel. Hydroplanes ride on two side sponsons and the very aft center portion of the hull. They may use either inboard or outboard power.
