Hang IV

Does anyone know what the record length of time is for an electric powered RC flight. I was wondering if anyone even considered looking at that kind of record be it official or unofficial. I just bought an electric RC, just for the idea of seeing how long I could keep one in the air just gliding and riding thermals and using power only when needed. I would love to hear from any others who may be interested in maybe having a little online competition fun setting soaring duration times.

Thanks, Bill
