This is my sub 250g LR wing build.
Cobra 10A ESC, Cobra 1407 3500KV and Emax ES9051 Digital servos are included in the PNP version.
Didn't test max flight time. But my current longest trip is 22km in 30min and took half of the capacity of 18650 2S 3120mAh VTC6 pack. Avg 70mAh/h at avg speed  40km/h. More efficiency can be achieved at a slower speed.
Update 2020: Cleaned interior and changed FC to Matek F411-WSE

Where did you mount the board for the Caddx Turtle?
It is on a right side in the front near battery. You can see it in the photo.
