"Possibly. I have the same configuration, however use a 20C 800MaH. The problem may be the C rating of your battery. The other issue I had was that I had to change the maximum PWM rate in the Multiwii code. The standard value was not high enough."

"3D printing this is a bad idea... The majority of the materials (at least the affordable ones) used for 3D printing are very brittle and will not withstand the vibrations/impacts of a quadrotor."

Small quad frame - CG considerations

Hi, I am building my first quad frame.Its a tiny one (frame length about 200mm), and I have some doubts about weight distribution.Since the frame is very small, I have a very limited choise of electronic component distribution on the frame. My question is, considering the CG is way off from the geometric center of the frame, how hard will the motors work to keep it stable, and if there is a limit to how much uneven CG the ardupilot board can handle. Thanks.See More

Assaf Weiss replied to Assaf Weiss's discussion Problem setting up flight modes
"Yes, I mean in APM planner. In the panner I get only 4 modes, two of them are not what I programmed in the CLI and three more are the same mode... So you say that I can trust the CLI to indicate which switch position is the correct mode?"

Luke replied to Assaf Weiss's discussion Problem setting up flight modes
"When you say you go back to Flight Data -> Status, do you mean in AM Planner? If so, you should know that Planner will not display all modes, because the Mavlink protocol does not recognize all APM modes. For example, there is no RTL, instead,…"
