Hi there,
This blog will document the flight of Ivory Ultimate. It's not necessarily the best Ivory launch, but it's definitely the last.
This launch features 6 small helicopter fans as active altitude control, 700 mA of solar panels to recharge batteries, and back to our favorite 850 MHz Yagi antenna.
Barring technical setbacks, launch is 9/29/2009 in the early afternoon CDT.
The Antenna is a reproduction of Ivory V4, 850-MHz tuned Yagi.

Here's an early image of the assembly of Ivory V6, Ivorycopter Beta a.k.a. Ivory Ultimate.
