C.C.W motors are hot than C.W motors

[pevisone]

Hi, guys~ I'm trying to develop the hexcopter control system(X frame).
I discover that my C.C.W motors are hotter than C.W motors after flying.
I have checked each ESCs and motors, they are on normal.
The output of my pwm value to the motors are the same when the hexcopter is hovering
Can anyone give me some advice ??? Thanks~

It sounds like you have a torque bias in the motor alignment which is causing two of your motors to work harder to keep a heading.

Dear Denny:
I have also checked the six motors alignment, it is almost the same~
but the CCW motors always hotter than the CW motors.

Is it possible that when you are flying you are making fast turns and only in one direction? This would make only one set of motors hotter than the rest.

What motors, what props, what weight, how hot?

Dear Arxangel
As a matter of fact, i don't make "fast" turns, and i have tried to make it fly in different directions. Yet there is a problem when i try to fly it clockwisely; the thrust increases (i.e. the height increases) but when it is flying c.c.w, it stays at the same height.

You definitely have something wrong with the thrust. A bad prop. or a bad motor.
