Please check out Bob Carlton's website www.silentwingsairshows.com to
see that he has not one, but TWO (Jet Silent - Moterglider and Salto -
Pure glider) night certified sailplanes which he does airshows with.
(NIGHT aerobatics in a glider, I might add!) I'm sure he would be happy
to answer questions via E-Mail. I know that he got around the onboard
generator problem somehow, but do not recall the exact details.
