  • How long and high does it take for the launch blloon to cease elevating and strt to decend filling the main balloon?

  • It is towing a giant condom?

  • The tow balloon is a standard 800g latex weather balloon... The solar Montgolfiere suspended below (deflated) was made from 8 micron thick high density polyethylene film. The spreader ring (not load bearing as in my previous tetroons) at the bottom is a $2.88 generic hula-hoop from Walmart.

    Payload contains a Microtrak 300 transmitter and encoder, Geko 201 GPS, DC-DC voltage converter and two 9v lithium batteries.

  • how was it made?
