Hi, I am planning on doing a land survey on my uncles 18acre hillside land, more than half covered in woodland. My quad is flying and able to carry up to 4kgs of camera gear, so my a7 will be a doddle, tho, I need to stick to the gopro copy for practice! I was going to just make a video of...

Hi, I have posted here, but it was quite some time ago. My quad project is well on the way, with all of the motors running via 30A esc's via Arducoptor APM2.8 . Motors are confg'd for H> quad, props balanced. It runs up very well, however with props on it flips on take off... When hand held...

Hi. I began building my quad from scratch, learning along the way. 2 years ago, after it's first flight, and crash, I set it aside, until now. I seem to have forgotten some of the info I had gathered previosly, such as which model of controller I am using, and which version of Simon K software...

Is there a reason that all the Quad's I've seen only use 2 blade props? I am pondering this subject as a means to getting a little more lift/volt... Perhaps 2 blade is more efficient, is this correct? I do understand that 3 blade will be a little heavier, however, this might be reduced by the...

Hi there... I am planning abuild... I've gone ahead and bought a Quattro 4x20a motor controller... that's all I have so far (super low price... couldn't resist!). I am planning on a "H" style Quad, and am pretty comfortable with the build... the unit, once it's had problems worked out, (and I...
