Drifting problems ?

[Srocupado]

Hello Guys, greetings from Brazil !!!
Before anything, thanks for this wonderful community, it has been REALLY helpful.

I´m running MegapirateNG 2.8 R3 on a Crius V1 with a quadframe and here is my problem( ): when I´m flying on stabilized mode, my quad cant hold it´s position. It keeps leaning to the side I just set the stick to, so If I apply left stick and then center it, the quad will come back to center but with a little tendency to keep going to the left.The quad doesn´t wobbles.
It happens in every direction.

I´ve already calibrated the radio, acc and mag.
Any clue ?
Thanks in advance.

Sounds like it needs trimmed.. 

You can also use auto trim https://code.google.com/p/arducopter/wiki/AC2_AutoTrim works in MegaPirateNG as well.

I agree sounds like it needs trimming or vibes are affecting the sensors

Trim would be always on same direction, right ?
I get this on every direction. I if go forward and center the stick it keeps going forward (very gently).
To counteract that I push backwards and center the  sticks, then it keeps going backwards (again, very gently).
I will check for vibrations then.

Ive never seen megapirate sit as still as some thing like the Naza

Gaza, just another question.
I do have a CN-06 V2 gps (serial), is it necessary to use the ublox software to set the baud to 115200 and 10hz ?
Will try to fly tomorrow with new FC support.
Thanks.

Hi Srocupado you dont need to do anything to the CN-06 v2 Gps because the megapirate and multi wii firmware send setup commands to the Gps each time it is booted up
