===== Plan =====

 A simple parafoil design with all control functions running on a single AVR microcontroller. This drives a servo, possibly a winch servo, to control a modified parafoil kite by draglines or C of G shift.

A cheap parafoil off ebay will be used for development and possible launches from altitude.

===== Schematic =====

 The second servo channel can be used when under RC control for an ESC. As there is just under 1KB of flash free, a bootloader, probably from [[http://www.societyofrobots.com/bootloader_50_robot.shtml|here]] could be used, although the GPS and radio are using the UART, so a jumper would be required.

===== Mini Rogallo test vehicle enclosure =====

This will be used for testing the concept before larger parafoils are flown.
