prop which broke was CW, no spares! Timing!
@sooraj it hit a rock nearby wen it flipped..

Exact situation occurred to me once !

Few tips,
Test your quad in soft prop friendly situations, Like Thick grass or bed or even a heap of sand or mud (But take care no dust get in to motors)

Also don't apply more than enough throttle to get all motors running, before you tune and setup your quad - for tuning purpose 20 - 30% throttle will be enough - No harms.

If due to any reason, you lost control, a timely cut off of throttle can save you from extra damage.

And I know it is so frustrating that you can't test your quad just because of a prop, So A quick remedy - Wisely use quickfix on your props (Thanks to Arun.sreelakam for the idea) Let it dry - Take my word, you don't have to fear to try hovering your quad with this quickfixed props - with a gentle throttle control, you can safely, maneuver too !!!
But throttle control should be very GENTLE This is No time for ACRO- Happy flying Smiley

What I thought  was to cut short the 12 inch prop to 10 and try it....

No - that will affect balancing and aerodynamic property of a prop (If there is such a thing!!)

Best way to test your quad is, quickfix your broken prop itself, Just be patient till the Quick fix finishes it's action wait for at least half an hour - this glue is a wonder once let to fully set Smiley

@Iyer sir, Not an argument,
I don't want a repaired prop to sports fly my quad, but for tuning it up and stabilizing while hovering - this helps, but USE WITH ATMOST CARE.
I personally used the trick many times, with out injuries to person nor equipment (I know that won't be the case always)

SO, I TAKE BACK MY SUGGESTION, I DON"T WANT ANYONE TO BE INJURED DUE TO MY STUPID IDEAS Sad

Hello everyone!

I was examining with d observations u all shared... And I made tests with props off..
I noticed that wen I move elevator stick forward M1 slows down and M4 speeds up(which is correct), wen I move rudder to right M1speeds up(after I reversed in my Tx) but M4 should also speed up right? But it doesnt..wen I move rudder to left M4 speeds up which it shouldnt..
correct me if I am makin any mistakes

Was this testing done with self level on? If so, that could cause these odd results.

Seems like an odd problem. Maybe it is something to do with the firmware. Which firmware are you running?

Well, it seems you have to read my explained post now Smiley
The motor 1 and motor 3 should rotate clock wise and M2 and M4 should rotate CCW.
If any motor is not rotating the needed direction, swap any two of 3 wires from ESC to motor Smiley

Right motor config. attatched,

Reset you KK2 board,
Load Quadcopter X motor config.
Do the receiver and acc. calibration and tests again.
Throttle to 20 %,
Check all motors are rotating required direction, if not reverse the motor.

Now everything will be fine Smiley

When you give rudder left, M2 and M4 should speed up since they are spinning CCW. Are you sure all your motor connections are correct and that they are all spinning in the right direction? M1 and M3 should be CW and M2 and M4 should be CCW.
