I am hoping to get some advice from experienced users - this is my first build and I am unsure on certain parts and requirements. Once complete, I will be making a guide for new users based on my learning experiences to date. The end state will be a drone that has stable hover and is fitted with a thermal (FLIR One transmitting via Linux driver/Raspberry Pi) and SJCAM GoPro FPV. Background The drone was purchased for £130 as a complete but untested project - the previous owner could not program the Naza - I suspect the wiring is incorrect and he was unfamiliar with various modes for Cleanflight etc. http://www.ebay.co.uk/itm/TBS-Disco...QhY5RBPDq1pCApKOQJGoI%3D&orig_cvip=true&rt=nc Current Build The drone has been stripped for a rebuild. The soldering was terrible and most of the cabling was bastardised; it looked unsafe and I did not want to risk a dry solder or poor connection. Questions 1. What type of power distribution board do I need to get? I do not have enough knowledge on this element of quadcopter building to make a decision (the last one has an OSD - no idea how that would feed in to my FPV). I was looking at the following: http://www.ebay.co.uk/itm/5V-12V-Ma...223951?hash=item2825c2eecf:g:USAAAOSwEzxYQ~p8 http://www.ebay.co.uk/itm/NEW-V3-1-...861237?hash=item3aca6727f5:g:aSoAAOSwqz9Zyl0R http://www.ebay.co.uk/itm/XT60-PDB-...083471&hash=item2a72b3060a:g:I8QAAOSwkspZcJmI http://www.ebay.co.uk/itm/Mini-Powe...258859?hash=item1a2f08d9ab:g:5FkAAOSw-itXqdA9 2. What cabling is required to link the ESC to the power distributor? As you can see from the pictures, there is a mix of sockets and pre-existing solder joins. What is the best option? 3. What other parts are required to make this a stable quadcopter? 4. I normally fly a Mavic Pro having moved up from a Phantom 3 so my experience to date is arm then move in to a hover. Can I fly this in much the same way or will I require additional parts (from question 2)? 5. What FPV gear should I use? I have a Tarot TX and a GoPro direct TX Following this guide for current build info: Please see pictures below: Original wiring (I think the LED and AUX 1 on RX are incorrect) Component parts, after strip down Proposed layout (RX on the top plate when installed) - advice appreciated!
