I have recently been given a set of Waltron radio gear: transmitter, servos etc. It is a Waltron 4-5 Sportsman, 4 channel 27 mgz set and in mint condition (it has been living in a loft, in a box with a price tag of £107.00) used once a long time ago. Obviously, the nicads are suspect but seem to be taking a charge. The gear should be practical for surface use, boats or cars. I would like to know a few details, such as range, problems if any. Anyone out there remember the kit? I would date the set at least 20 - 30 years old. Address of the manufacturer on the box is Waltron Electronic Controls Ltd, Westwood Industrial Estate, Cross Lane, Marple, Cheshire. Anyone live nearby? Is it still there?
