Lightweight 4" 1407 3600KV.

Maiden flight 7/1/17. Flies beautifully! Plenty of low end power. Not enough room in my yard to let it rip. Motors were hot, but changing motor timing from medium to medium high seems to have fixed that. Was able to turn d_lowpass_type to PT1 without getting them hot again.

Overall impression: Totally stoked!

Build note: I had to add plastic nuts on top of the blue aluminum spacers to give enough room to fit the X6B receiver. This made less room at the top of the stack. I couldn't use padded double stick tape to hold the VTX to the top plate, but thin target brand double stick tape and a zip tie seem to be working well enough.

7/22/17 Got KingKong 4045 biblades, retiring DAL J4045 triblades. Motors come down much cooler. Had to reduce D gains right off the bat. All thanks to @bahb on that tip!
