Sport VRLI: LI-poly power for glow-powered planes!

Article Abstract:

The Sport VRLI (voltage regulator and LED indicator) at just 1.25x0.75x0.5 inches allows to use Li-polys batteries to power the airborne RC system. The VRLI reduces the higher voltage of two-Li-poly cells to a regulated 5 volts, which is most suitable for operating the average RC airborne system
