ohhh those are acrylic sheets... ya man they are very hard to cut, i am using them for the stands.. and thanks for the smiley balls suggestions..

Check the flight video in my other board and please give me your valuable suggestions i have one more will upload by eod today

 
I had problem where my quad use to rotate on yaw axis, but it used to take off. Today Dharmik bro advised me to change the fw to kapteinkuk 4.7 version. I did that and after that there is unique problem that i am facing..

Only left and right motor respond to the Tx signals, front and back motors start spining but only after 70% throttle.

My pot settings Roll & Yaw are on 50% roll is on 10%

Also the left and right motors spin on different speed, i tried the trims but still one spins faster than other.. Never matches, and its very hard to get them spining at same speed.
Help me with further trouble shooting guys..

I will loose my mind, it just makes me crazy. I dont understand why it was working and just changing the plates totally stopped it from working.. 

Couple of things,
While calibrating ESC something i noticed, the beeps 2 motors gives beeps at a very low volume and other 2 are very loud. Just to let you know these are 2 new ESC's i bought 2 after i burnt 2 out of 4 which was bought all together.

I want to know, do esc differ?? i mean i am using HK 18/20A ESC but the once which i had bought now (after burning 2) had different sticker than other, now the motors connected to these ESC's give a loud noise. I know all ESC's are same but just wondering

Satya bro it's throttle calibration issue due to refresh rate. Are those escs are same? I mean same brand? Same Amp rating but different brand won't work.
If all escs are same then 1st check manual carefully. It should have setting "restore to default". This step is not necessary but sometimes we just change other settings by mistake like one esc has lipo mode, the other one has ni-xx. So when you restore them to default calibrate them individually and then connect them to the board. Put yaw pot to zero and raise throttle to the max(no props). Then power up the board. Now calibrating escs together is bit tricky. If you failed to calibrate properly motor fourth, third or sometimes all will start in random order. So you have to bring throttle stick down swiftly when ALL FOUR BEEPS OF THROTTLE CALIBRATION END AND NEW BEEPS OF OTHER FUNCTION STARTS. You have to bring stick down between them exactly if your motors don't start all together. Many people on rcg have 4th lazy motor issue but i have fixed mine easily. You have to do this only once. Then for more safety change battery mode to ni-mh.

Bro this is the motor which i have..

Even i was thinking the same, there is some problem with the calibration...
And here the manual i dont find any reset to default

But i will surely try these steps, thanks for suggestion..

Ya i checked that manual. It has 3 functions. Try calibrating them individually and then together. I hope it will fix your issue.
