Problem "unsolvable"...

[saprile]

Hello everyone, someone would know risolve this problem?
I tried in every way to ESCs calibrate (manuals, howto, etc. etc.), but there is probably some other problem that must be solved for the different speeds of the motors.
The hardware and software used are Arduino Uno, GY-80 IMU and MultiWii.

Thanks!

The motors are going at different speed because you have the quad pinned down and any adjustments it tries to make are not happening since it is not in the air.
Also, you have bad vibrations and your mag is messed up bigtime.

But my quadricopter can not fly because part wrong and crashes (https://www.youtube.com/watch?v=LnZO1HVBHso). If I try to balance it with the right stick, it loses power and does not fly. What should I do to make it fly straight? And the vibrations?

Thanks

You either have:
1- motors plugged into the wrong FC outputs
2- the sensor orientation wrong. Search the forum for this sensor to find out how to use them.

What flight mode? Angle or Acro?

Hi Waltr, the motors are connected according to the attached diagram, the sensor is in the right direction, in fact MultiwiiConf movements quadricopter are correct. I've tried both ways acro and helicopter.
I do not know what to do...

Could just easily be that you are not giving it enough throttle. Or ACC cal is way off, or TX sticks are not properly setup for center and end point values. Or simply "ground effect" from the prop wash.

Setup it up for "tuning on a string" so you can trouble shoot without crashing.
