- What is the duration limit for a pure thermal (no slope assist) duration flight?
Well theoretically . . . . With unlimited funds and unlimited technology including semi-autonomous flight, solar-or-otherwise recharging power system, and night thermals - indefinitely ;-) With current technologies, good weather, great batteries, good eyes and great endurance - from sunrise to sunset. Roughly 15 hours on June 21st at North American latitudes! A catheter and support team would also be needed. "My bag needs to be emptied." "Aww, I just did that." ;-) RCSE-List facilities provided by Model Airplane News.
