"Valeu Sandro!"

"Thanks my friend!   From what I read they are similar works with UART. But will it work in practice?"

"I have not used them, however they look a lot like these that have been talked about a few times.   I hope this helps a little   Regards   Martin."

"Hi, I noticed you're using a wireless RF transceiver module 431-470MHz GFSK. Is it used to stream video?, What kind of camera are you using? regards"

"hum ... now I understand. Guys, thank you for answers and help. I hope soon to build a UAV and share with you my accomplishments!"

"Again, GPS would give you that, unless as Alex mentioned, if you are hovering, GPS can't help you any more."

"The magnetometer is used to see the heading. isnt? I want to see the way I'm going."

"Thanks!"

"you don't need the airspeed sensor or magnetometer to have your UAV flying, however it is advisable to get an airspeed sensor, the magnetometer you dont really need unless you are going to be hovering"

"But even with the oilpan, still need the pressure sensor for airspeed and the magnetometer, isn't? Thx"

"Arduimu doesnt work with ardumega... use the oilpan for adrumega"

"I will buy this plane, ardupilotmega, arduIMU, GPS, Xbee, sensors, camera for FPV, Tx and Rx. Engaging my camera to perform precision aerial photographs. Any suggestions?"

"If you want to go with a cheaper route than the EasyStar I would suggest the dynam hawk sky. With the hawk sky you can buy a ready to fly kit witch comes with a motor already powerful enough to us as a UAV. Not to mention that I have dove it into…"

"OK. the Easystar can carry a Sony W90 camera? Thanks."

"EasyStar is the best way to start."
