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.
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

Gordy and Michael Volz attended the two day contest at Visalia. Gordy madeit to the second page of results with his Emerald.
Jim discusses going to AMAs Muncie IN flying site. There are 1000 acresof land to use attractions in the area and amenities provided on site
The end of the U2 project describes slope soaring testing in November.After adjustments of CG and elevator response the model flew well.
Information about the properties of Brass alloys Carbon Steels andStainless Steels. Finishing of 400 series stainless and carbon steels.
Steves winter project is the Northrops X-4 Bantam. Giuseppe Ghislerihas made a 1/6 scale version which works very well. Good history of plane.Discussion of design considerations of camber thickness twist CGlocation drag breaks trailing edge effects discussed.
Recommendations on what you can do during the non-flying season to helpinsure the continued successful experiences with your models.Check wiring for cracks switch servo leads gear wearand linkage slop. Look for loose hinges. Fixing now is best possible time
