Tony Crollie’s Maplin Speedboat

This boat represents a triumph of development over design – a Maplin toy R/C speedboat has been adapted to use a ‘hot’ 400 motor controlled by a forward only aircraft-type ESC powered from a two-cell Lithium Polymer battery. The wide-band radio gear has been replaced by a ‘proper’ crystal controlled 27MHz receiver and the bang-bang steering upgraded to proportional by installing a servo. The high speed running achieved has required strakes and trim-tabs to be added to the hull.
