Duration records could easily be improved. ie 3hr something for thermal flight. I have done longer thermal flights than that flying a 2 channel Spirit 2m. Pity they were not claimed.:( I attempted a slope record going for 48hrs, but had trouble flying at night because fog came in and I lost all viz and reference to horison. Other than that I most likely would have done it. I was around 15 hrs when i aborted. Glider was a 3.8m scratch built and carried 2.5kg of dry cell batteries. Will be easy now with lipos and the fancy radios. Imagine what could be done with a transmitting vario etc.

Come on guys !!!!!!!!
Everytime you go flying, try and learn something new. You are never too old or experienced to learn new things.

Cant be verified , beside take my word and that of my old mate Wayne upfold , in 1991 hand launched a gentle lady (around 2m wing span me thinks ) and flew for 2.5hrs (Both piloting, relay style) , came down because neck's were sore and started getting worried about the batteries! it was off the sports fields at "Leer gevegs skool" near postmasburg , during our army days in skylift!
Clearly Weekends are made in china . They simply dont last !
