This is the FahPah "all up" kit, with an added XBee Tx and Futaba R6008HS.
Arducopter NG software, untouched except to enable XBee. No magnetometer.
Turnigy 2200 3S batteries.
All bullet connectors soldered shut, which resolved the burning-motor problem.
I'm not sure I mounted the ESCs as intended.. it appears each of the arches has a protrusion that may or may not be useful for ESC mounts.
The in-tube motor wires makes a very clean package, and the "wedding cake" racks make for a compact center.
The GPS Hold mode was the only confusing thing, since it seemed to have a lot of wander and a very aloof and unauthoritative throttle control. It tried to drift down into the weeds and I had to switch out of GPS Hold to recover it.
So far, so good!
