Hello everybody! I would like to introduce EasyStar (with a few mods) UAV which uses PIC32 based autopilot that I've been working on for a few months (started a few weeks before Brian Wolfe showed his work on DIYDrones ;-)
Right now it's build upon UBW32 board but in the future I plan to desing my own PCB and decrease the size of the autopilot. For attitude estimation I use FMA thermopiles. Xbee is used for telemetry (interestingly 2.4Ghz Pro module which is rated for 1.6km worked easily for me allowing for 4km distance between two transceivers). More details will follow soon.

Below short autonomous flight (looping through four waypoints, windy day, gusts up to 20-25kph)
