I received my board yesterday from anam sir. Since my previous quad is allready tuned, I just need to replace FC but I will have to change direction of landing skids as they are set for plus direction. If everything goes fine I will post test video soon.
If anybody having trouble with setup please check this guy's blog

Any changes in the board??

[Dharmik]

Satya bro i see some new features. Now main screen shows battery voltage. Here are some changes according to KK

CHANGES:
1: Removed: LCD contrast adjustment: Not necessary.
2: Removed: "I of PI" on/off mode: No practical use found.
3: Removed: I part of self-level: Does not work with slow reacting ACC.
4: Changed: default gains to 50/50/50 (roll/pitch/yaw) P-term, and 25, 25, 50 I-term.
5: Added: beep (short beep, 2 sec delay) when armed and throttle closed, for extra safety. Makes the KK2 a bit more noisy when armed so the user does not forget it is armed.
6: Added: longer arm/disarm beep.
7: Added: ACC trim. Use it to adjust self-level attitude, no need to recalibrate sensors. Adjust in "Self-level Settings" menu.
8: Added: factory reset.
9: Added: status messages on the "SAFE" screen. The KK2 will not arm unless it says "OK.". Error messages can only be reset by cycling the power, except for the "sensors not calibrated" message, which is reset after a successful sensor calibration. Error messages include lost RX connection.
10: Bug fix: wrong offset in flying wing mix table.
11: Changed: doubled self-level stick response. Let you have more control in self-level mode.
12: Added: CPPM (sum PPM) mode. Turned on/off in "Mode Settings" menu. Also the assignments of the CPPM channels can be changed in "CPPM Settings".
13: Added: Y4 and V-tail layout.
14: Added: shows battery voltage on the "SAFE" screen.
15: Added: lost aircraft alarm. Starts to beep (1 sec on and 4 sec off) after 30min of no activity (arm/disarm).
16: Added: LP filter on servo outputs. Adjust in "Misc. Settings". A good start value is 50.
17: Added: auto-disarm. The KK2 will disarm itself after 20 sec if throttle is at idle. For extra safety. Can be turned on/off in "Mode Settings" menu.
