Hi all,
New to this forum but not new to multi rotors, however I still have plenty to learn. My hobby for drones has recently turned into a business. My website FlyingTech sells parts and accessories, but better still I have tried to include lots of informational material/tutorials relating to everything from vibration dampening to prop selection. Please check it out and feedback would be apprepriated.
Here is snippet from my recent blog, I hope it's helpful.
Welcome to the second article in the Multi Rotor Beginner's Guide. In theory drones aren't complicated; the only moving parts are the motors. In reality, there is far more to them. To build a drone from scratch requires at least a basic understanding of physics, maths and technology; and practical skills such as engineering, wiring and even coding. To then fly the things requires further skill and experience. Obviously the the degree of knowledge and skill required increases with the sophistication of the UAV. Some multicopters come in plug 'n' play kit form, which means you side step a lot of the technical challenges.
My aim here to is to help reduce the learning curve for you, by providing some useful tips that will keep you on track or at least save a headache.

- Carbon Frames are conductive! If an exposed cable or connector touches the frame you risk an electrical short. Be particularly careful if you’re using a folding frame. If your wiring is tight and routed around edges, the insulation can wear over time as you assembled and disassemble your frame. Therefore it is a good idea to use heat shrink on vulnerable areas to provide an extra layer of insulation.
- LiPo batteries require careful management to maximise their life; they can be charged up to 4.20V and discharged down to 3.0V per cell. Any lower or higher in voltage and the cell will almost certainly be irreversibly damaged (reduced capacity or total inability to accept a charge). In respect of this it is common practice to abide by the ‘80% rule’. That is to not discharge you LiPo below 20% mAH during flight. 80% of pack mAh = pack mAh *0.8. An 80% discharged LiPo cell, will give an approximate open circuit voltage of 3.73 to 3.75 volts. A 3S LiPo pack therefore would show about 11.19 to 11.25 volts after a flight when it's about 80% discharged, a 6S pack would be about 22.44 volts….
