I have AutoQuad and ESC32 on their way (arrived UK and currently in customs) for my foray into multi-rotor flying machines. I already have Futaba high-end 2.4 R/C (I also have a Spextrum DX7s 2.4 for BnF toys but would not trust DSM2/DSMX on any “proper money” flying machine). I used to have JR DSX12 DSM2 but moved over to Futaba following several definite ‘glitching’ incidents, and following exchanging just the Rx from Spectrum to Futaba in the airframes, have enjoyed glitch free control for the past year or so in exactly the same models.
Now I need the rest of the kit…. Firstly the frame, should I simply go with a quad or is a hex better? I only want to lift a Gopro type camera (and even that not to start with), and may want to add FPV capability in the future, but flying quality and stability are the core aspect. I understand that AutoQuad really demands a stiff, rigid frame – for a Quad I had been contemplating a QAV500 but have been warned it is not rigid enough, and the TBS Discovery has plastic arms which I understand are also not stiff enough.
I have read Angel’s (afernan) Basic structural dynamics document, and although it is sound and excellent in its content, the math is just way beyond me – I am fully capable of making/building something given appropriate drawings/parts/components, but successful own design is out of the question. Angel’s result of his own design Quad Monoblock 620 or the Hex Monoblock 814 look to fly brilliantly, but as they is not available as a kit or detailed component specification/power distribution are is probably out of the question. This seems to leave the FPC HL Quad/Hex as the main best candidate, but again there seems to be little detail regarding construction/configuration/power distribution (which is all built-in with the QAV and TBS frames)/motors etc.
I can make bits – I have a small lathe and hobby CNC mill (which I am also learning….).
So I am just seeking some help and advice from you guys who know so much about AutoQuad based multirotor building and flying, and I currently know so little.
Is my best option to go with the FPC HL (which also has the benefit of supporting the chaps at Flyduino/Viacopter who support this forum), and if so in what configuration (quad/hex; arm length; motor spec; 3s or 4s lipo)?
Another good option appears to be the Vulcan MultiFrame Skyhook, I can start with it as a quad, and then upgrade it to a Hex if and when needed. It looks very rigid and strong, and is a UK product from a company with a good development history. Also of interest is the Vulcan Mantis 900mm Hex.....
I would prefer if the machine is not too big.
Any help or guidance or recommendations gratefully received as I embark on this new journey. I have an open mind (or I would not have chosen AutoQuad!) and am willing to work and learn – I just don’t want to make unnecessary big mistakes or re-invent any wheels!
