Let's not get heated up. If we are to help this young man, let's be sincere about it.

Roby go step by step. For the moment, forget about the props - Two of your motors mounted on either side of an arm will spin clockwise (check the diagram I have posted above). Have you achieved that in the correct positions?

Take off your props. Attach little pieces of adhesive tape to your motor shafts, power up the unit and see if the motors are spinning the way they should.

If they aren't, all you have to do is to de solder the wires going from ESC to motor and interchange any two wires. The motor rotation direction will be reversed. Got that? If not PM me your number and I will call you and talk you through it.

the props moving is right direction... opposite it same.. so checked
all possible reasons for problem:-1)my frame is a bit crazy... wood pieces mounted on pvc.. looks nice but i doubt frame might be a problem.
2)i'm not using a pdb.. all wires soldered.. can that be a reason for one of the motors to spin slow?
3)board is not screwed..maybe the flight is not stabilized... though i'm pretty sure that my acc calibration went fine

Merged.

This is your final warning against creating multiple threads on a single build.

People have to ask again and again in the new thread about what you equipment you are using, what have you done and tried so far etc.  It is confusing and extremely annoying, and I have got multiple complaints about this. Simply put, creating a new thread on an ongoing issue defies every bit of the minimum common sense that we all should have.

Well prop and motor all together rotation is wrong and props are not balanced and flight control board is not mounted on vibration damping material

Are your motors alignments strictly vertical? Have you followed the youtube video and programmed the board in all respects?

Have you spoken with the carpenter? Ask him if he can cut you 2 circles of 6" dia from 4mm ply. They will serve as the mounting boards of your electronics = Controller board and Rx (upper level) and Battery (lower level).

quad wants to dance..Some issues with esc calibration or pi settings i guess..  :banghead: :banghead:
if anyone can fix it with a skype call or whatsapp guidance, and will correct me.. i have a very special rc gift for him :thumbsup: :thumbsup:,
will ship it for free  ;D

Issue is somewhat like this, but a bit more horrendous as it wants to flip even before it can lift itself properly



You can even have a hands on if you're from Delhi

Reverse the yaw limit in Mixer editor for all motors, as in if the Rudder= -70 make it +70
check the motor layout and check if the corresponding motors are spinning in the correct direction
Redo this step for whichever control is going out of control, turning in the wrong direction by itself
