Build an Electric Powered Model Hydroplane Plans
These are plans for a battery powered boat hydroplane.
Hydrofoils have been around for some
time, but even so, nothing on the boating
scene draws every eye like a hydroplane
lifting out of the water as it gains speed.
Even the U.S. Navy has been attracted
to foils, and has tested them on its fast
The PS model shown here can be completed
in a couple of work sessions.
Surface-piercing foils and air-prop drive give
it speed and stability with minimum complexity.
Construction is far simpler than
you'd guess from the performance.
Basically, these craft deliver greater
speed because resistance against several
small areas (foils) is considerably lower
than against a complete, submerged hull.
Resistance declines as the craft rises.
Completely submerged foils are the
most efficient, but they require sensing
and control systems to keep them at
proper depth. Surface-piercing foils automatically
adjust for depth—but they
also have a tendency to create air bubbles
that reduce lift.
The PS model uses
a foil design that minimizes this undesirable
