Bit of a wet day here so I put some time into this project. After quite a lot of experimentation about how to mount things I came up with a rough layout that I was happy with so I started with mounting a motor.
These are Gartt 4112, 480kv motors. It turns out that for a big-ish drone you need larger, lower kv rated motors to swing large propellers and then use more battery cells (i.e. higher voltage) to run the lower kv rated motors.
Having got the motor mounted I fitted the ESC underneath, there is some debate about the maximum length of the leads between the ESC and motor so I thought i'd keep them short and that meant there was a bit of wire cutting and soldering to get it connected to the power board. Given that I wasn't entirely sure I had got this right and again there isn't much info on t'web I wanted to test out the one motor before mounting the others, cutting leads etc.
Testing the one motor meant I have to get pretty everything mounted and running because the software tends to complain if it can't find all the essential peripherals.
So that's a fairly temporary set up for the time being. After going though quite a lot of set-up and config for both the flight controller and the radio tx/rx and several false-starts with getting it to arm, I got the motor running, so fa, so good
