I've found this interesting article in IEEE Spectrum this month. Interesting method of propulsion which isn't addressed in the slide show.

We are coming to the end of the next round, who's up for giving me a hand sorting it out and perhaps making the judging a little more subjective.
Have any of you guys used the 2.4ghz DIY conversion kit from Hobby King??? I ordered one yesterday, so I'll follow up here after I install it, but I was hoping for any "heads up" that I could get before I start.

Hi Guys,
Hi guys,
We are using AT89C2051 for generating PWM for each motor and alreadycontrolled speed of each motor by varying duty cycle using a pushbutton.Still we are unable to control four motors using RC. Weprogrammed for sensing PWM out of RC but value is rando

Can you please tell me where to find the instructions for the HMC5843 - Triple Axis Magnetometer
How to set the voltage jumpers, I2C address and some arduino example code would be great.
Thanks

Hey Everyone,
Our goal is to eventually get Ardupilot 2.4 up and running in our Easystar... here is our equipment:
Ardupilot Arduino ATMega328 Board (red board)
Shield V2 kit (blue board)
EM-406A USGlobalSat GPS
Spektrum Dx6i transmitter, Spektrum AR611
