roll pitch work only in one direction

[codeforge]

Hi,
i have a quad with simonk esc and rctimer 5010 motor 15" prop, autoquad v1 r37. i fly well in manual and gps but after 5/6 minutes when i roll full to left the quad roll a little bit to left but if i roll to right the quad goes very much to right like the middle point of roll is decentered. Same with pitch, full forward from transmitter and the quad goes a little bit forward, full back with pitch from transmitter, autoquad goes very much to back...

Could be an esc problem?

Flight log is the law around here. If you have the SD card in take a look and see if it's a transmeter/ receiver problem or one ar many other possibilities. If you can't make sense of the log post it here.

Hi,
i try to check the logs but cannot understand if there are problems. I see the quality radio and all seems good.
There are 2 log files, the first of the good flight with at end the issue, then i land in gps to avoid crash. The second is very little because after gps fix i try to take off but i get a back flip, then i try it in my hand giving a little throttle in manual mode and i see the front left motor spin much more than the back right motor.. Cannot see else. Tomorrow i try other flight hope to save 15 inch propellers if crash :s

thanks again

I could not open the file. If you have not found the problem repost the problem again and maybe someone else would be able to help.

Uneven thrust distribution is usually caused by range difference on the ESC´s. Recalibrate all ESCs

Otherwise there could be a problem in your calibration of the board itself....
