Length 25" Power Sail Radio Controlby John Bone
Akela is one of a series of small models built to self-imposed rules at around using standard two-channel radio equipment without a sail winch. The square-sectioned hull is built "sides first" from 25mm balsa, bonded throughout with Superglue. This particular model has been coated with epoxy resin but is also suitable for doped tissue or Solarfilm covering.
She carries 12oz. of lead on her aluminum fin, the all-up weight, including half a pound of radio, being 29oz. The swing rig is handled easily by the servo, coupled via a long lever attached to the side of the hull and giving very rapid sheeting control. A standard four-cell Ni-Cad pack, which will give several hours' sailing with sensible use, is carried "saddlepack" fashion on either side of the fin as it sloth through to deck level, effectively dividing the radio compartment in half.
The radio installation has to be very compact in order to place it directly over the centre of buoyancy, minimizing its moment of inertia and the "dumb-bell effect", important in a small sailing model.
