I decided to convert my Y6 to the new frame 10 option. Of course, the motor cables from the ESCs were only reachable by taking it apart, top frame off the bottom frame. I labeled them as they were, disconnected, then re-connected in the new position. Then whoops, taking off my hand made labels I knicked the signal wire from one of the ESCs. First glance, only got the insulation. Taped it up, and will try a motor spin test. I will go back and double check the extent of the damage, presuming all motors are correctly spinning now.
My concern is the 3DR ESCs wiring is very small gauge. Stripping insulation of very small wires, so I can solder the two ends together, is challenging, but will give a safe connection that I could trust.
