A DG 400 with a broken crankshaft was recently rescued from being a conventional launch glider only, by fortuitous sourcing of a second hand crankshaft by a well connected professional workshop. My own, Ventus 2CM suffered a burnt piston when engine was 10 years old with fifty hours engine time. Neither Schempp Hirth or Solo could provide the required spare parts. this engine no longer supported I eventually flew the glider as a self launcher two years later, after locating a small workshop with the capability of making pistons from poured metal. Now my glider is U/S engine again with an U/S water pump. Surprise, surprise, neither Schempp Hirth or solo can supply the simple seal or impeller needed to fix it. It looks likely that I may be able to get the engine airborne again by fitting an electric water pump, as is currently used on the Arcus.All at great cost of course and with no apology or explanation from Schempp Hirth as to why their support of the engine on the Ventus 2CM ceased inside ten years from manufacture.

Re: [Aus-soaring] battery power
The vast array of PV solar panels on the hangar roof? These require burning non renewables for manufacture (mining the metals, processing, transport, installation etc.). Making PV stuff is CO2 intensive, see http://www.lowtechmagazine.com/2008/03/the-ugly-side-o.html ___ Aus-soaring mailing list Aus-soaring@lists.internode.on.net To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
