"It is not even half the price. Summarize unworkable GPS LEA-6H with reversed contacts, power module, case, wires, soldered pinounts and you will find a little profit of 3RD behind APM. "

"GPS pins inverted? :D "

"A. Just make H-frame - solved. B. Sure, you didn't solve it. It is HUGE and produce much vibration due to lenght. C. Agree, but still don't understand you design, sorry."

"I don't understand why make it so big? Simple is better. Look at Zenmusse and other professional gimbals."

"When you are using beta version expect to fail sometimes. 3.0rc1 is beta, not stable version yet. "

"Latest version is 1.2.50. I tried to install it as fresh install. Still don't work. I have compiled code in Arduino IDE and flashed."

" I have same issue since APM Planner 1.2.48 and AC 2.9.1b. Sometimes it is just Connection Error - No Connection and sometimes as on screenshot above."

"probably reversed propellers ?"

"I have 2 Hero3 BE's ordered in a different time And i don't have any problems with it since FW update."

"o O"

"Start with Wiki for ArduCopter https://code.google.com/p/arducopter/wiki/ArduCopter It is almost complete from A to Z"

"i've once inverted output 6-pin cable and had this result. backflips is about wrong connection/propeller direction "

"Clone? This is chech board, it is located in Chech according to Ebay.  Are you REALLY sure it is cloned? :D Your paranoia sometimes making me laught a lot"

"The posibilities are endless, it is only question of processing power and ability to realise it in code."

"How about folowing mode, when aircraft recognize you for example by IR beacon or your clothing color.  More important thing for the moment is motor feedback. When controller really know how fast your motor spinning and how much amps each motor…"

"obstacle avoidance, enough power to collect any logs possible for example. high resolution optical flow processing for precise movement"
