"Looks like you've achieved some nice cruise efficiency even with the lifting props, fine work indeed. I'm guessing the wing extensions help there. What amps is normal cruise at? 4s? Congrats on getting it all working together and tuned so well."
"ah, it was a NTM Prop Drive Series 4238 750kv / 785w.
I think I can possibly eek a little more efficiency out of the x8, with a fixed prop and some cruise speed tuning. with li-ion cells, 150km should be no problem too."

"yup, that was my 113km flight from yesterday. here's the setup:
batts were 3 x tunrigy 8400mah 3S, total 25.2 amps. All up weight 3.8kg.prop is a folding 14x8.
APM 2.6 controlled the entire flight, from full auto bungee launch to the landing. No…"

"Same as above, I have struggled to find out how to display google earth with qgroundcontrol, I can't figure it out at all. any advice? . os x 10.9. the manual is no help. it will be awesome when this is all working. "
"Hi Brian,
I had exactly the same issue when first running an APM in x8s. It was solved by levelling the airframe to be in a slightly nose up attitude. If you sit the airframe on a flat surface and lift the nose so the "chin" lump is about 5cm up,…"

"I've found the best airframe performance (trim and efficiency) to be slightly nose high, about 3 or 4 degrees AoA. I just put the x8 on a level surface and put the lid under the nose to lift it about 1 inch, that gives a few degrees nose up and it…"
