Have you tried the 'stable trim'?

Dearm
Throttle to full
Move the pitch or roll stick to add a 'click' of trim as needed.

In your case I would say try 10 or so movements of right roll.

botton of config.h you need to change

//#define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = Y; accADC[PITCH] = X; accADC[YAW] = Z;


to

//#define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = Y; accADC[PITCH] = -X; accADC[YAW] = Z;

quick easy way to tell if acc axis needs changing

link to gui and rest multi on an angle if axis is correct angle will remain constant in gui if axis needs changing angle will return to level over a 20 to 40 second period

I was maidening my Quadrino tonight and found the same thing. I forgot about the disarming and doing the tapping left, right, up or down. This works with the Quadrino boards as well correct? Also, you leave it in level mode correct?

PS: Also, is this only in 1.8 patch 2? I am running 1.7 at the moment..

my english is not so very good, what does "rest multi on an angle" mean?

the line is alredy "//#define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = Y; accADC[PITCH] = -X; accADC[YAW] = Z;}" but it is commented out. i will enable it.

is this right?:
acc and baro pitch and roll should go to the same direction: calibrated acc_pitch=0 acc_roll=0 acc_z=255. nose down pitch positive, right "wing" down roll positive. copter starts from ground streight up z increses. start yaw in clock direction in top view yaw positive.

line commented out (as original) it behaves exactly like this. when i enable the line, acc_roll and acc_pitch get inverted and it behaves very strange.

rest multicopter (quad?) on a flat suface then raise the back till its at 30deg and watch what happens in the gui over 30 seconds without moving the quad


the line is alredy "//#define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = Y; accADC[PITCH] = -X; accADC[YAW] = Z;}" but it is commented out. i will enable it.

remove the - in front of the x and try that instead

is this right?:
acc and baro pitch and roll should go to the same direction: calibrated acc_pitch=0 acc_roll=0 acc_z=255. nose down pitch positive, right "wing" down roll positive. copter starts from ground streight up z increses. start yaw in clock direction in top view yaw positive.

sorry someone else will have to help there as ive never really looked i tend to just watch what the arrows are doing and make changes from that for acc


line commented out (as original) it behaves exactly like this. when i enable the line, acc_roll and acc_pitch get inverted and it behaves very strange.
leave the line of code as is jst remove the -
