SoundMTB

Hi

You have to clibrate the GYRO with Software GUI and Sticks incl. ACC then it will work
Don't forgett to setup the Servo travel way in your RC coresponding to the GUI Value 1000-2000 on all Chanels
and learn the ESC on the RC.

Hi it's me again

I've looked to the code 1.7 vs 1.8 and I found that in 1.7 the Trim in ACC is done by one variable accZero for all axis.
In 1.8 I found to variable accTrim and accZero boout the accTrim is set on some places to 0.
Can someone help me to understand the funktions in the code.

Hi

I can confirm that the problem wasn't there in Soft. 1.7

I have the Problem with BMA020 and soft 1.8

It seams to me that it has somethink to do with the MAG, becouse a friend of my has the same copter (build by me) without MAG and he says his copter work perfect.
