Account of the first unmanned Atlantic crossing accomplished by a poweredmodel. The original goal was to provide weather data over oceans wheredata is limited about condition variation with altitude. Theproject was funded by Australian and US sources and active since 1991.<\/p>\n\n\n\n

GRP Vario allows autonomous control of a tug or a sailplane by GPS receiverand instructions for many details of the flight including take offdirection rate of climb maximum distance from a point maximumaltitude. The system could allow a tug to launch tow and land withoutcontrol from pilot. It also reports altitude and battery voltage.Scale models can be too light. Robins 1:4 Discus VI is too light for wind.The features described for the telemetry – GPS system sound fantastic. This would be a benchmark in technology. Electric motors for aerotowing are here. Silent launches so quiet that you can hear the models whistle through the air. Feature to find model<\/p>\n\n\n\n
