"I solved problem. I configured Y6B and connected to 1,2 / 3,4 / and 7,8. It can fly now."

"Hi Randy,

Does the min throttle out in recent version fixed to 1110?
I am using wii esc firmware and it fixed to 1050-18xx. So every times I arms the copter, the motors always spin.
Will I change the esc firmware or is there any way to configure…"

"Sometimes the copter loose the yaw, it twisted to left for about 90 degree. I flow in alt hold mode and did not touch to throttle & rudder stick but sometimes it lost its direction. Could someone tell me where is my issue?
Thanks,

"Hi,
I flied my Y6 about 1,5m-2m height at home. And sometime, it automatically landed for unknown reason. I was disable battery fail-safe. Could someone tell me why? I happened to me 2 times. The code is 2.90.
Thanks,
-Duy"

"I tested the new release at home and it worked like a charm. The altitude hold also worked great, I tested it just a little at home.
However, when I brought my Y6 to stadium to fly, the calibration got wrong, I do not know why.
Does the calibration…"

"Thanks the development team for new release. I just uploaded and did some procedure to set it up.
The new calibration is quite difficult to do, especially with my Y6 frame. Does it need to have a good level for all 6 axis?
After I did the new…"

"Maybe you forgot choosing the board.
You must do this and try again.

"I think that the root cause is from material of cheap motor.
The magnet has been reduced its magnetic and cause the lower power.
-Duy"

"You must use Arduino to compiler the code of 2.9rc. And then connect the board to upload new firmware from it.
You also need change some configuration on config file for your frame. These procedure is not very difficult but you must understand what…"
