You'll get about 1 Kw of solar panels on the roof of a trailer. You might average 500 watts unless you tilt them to face the sun and move them every couple of hours from sunrise to when you fly. Say 6 hours and 800 watts average. Might just do a 4Kw-hour battery in a Silent. Assuming clear sky

>>I think it was the first PRODUCTION electric SLG. See WIDOLA of that year. There was an electric Silent 1 for sale in around 2007. The Antares was the first heavyweight production glider. From memory, the original Silent had a pylon mounted motor. So far as solar panels go at night… most flying

HA, There's an interesting article in the current S&G about a casual comp done in Italy, flown with the Silent Electro. Was this the world's first electric SLG? I know it proceeded things like the Antares by almost a decade. Anyway, the innovation with the comp was that they were allowed to use t

competition sites will need to reticulate power and water loss of tug fees may be a issue, but what is the profit per comp on average for fees on a fully costed model? I assume electric self launchers are quieter? > On 18 Sep 2016, at 10:24 AM, Mike Borgelt > wrote: > > Even with the new
