They use MMA8452Q accel, which is currently the best quality digital accel available. That would explain auto-level stability. As far as I know sonar altitude hold is the only thing that was demonstrated as being "better", and that one is easy to do on a proper micro with enough PWM input...

Hi, This inflight ACC-calibration is really a clever idea I have adopted it for my JPWiiMultiCopter and slightly modified the logic to prevent going to LEVEL mode if the inflight calib has not been done yet. So my logic is : 1) At the end of Arming procedure, chaeck if the left stick is in the upper...

I can't imagine that the drift is due to the 8g ... My quad is drifting just when taking off very gently... 1.1g max. The problem seems to be subtle: the average value can be 1G, but the instantaneous values could exceed 2G due to vibrations. You won't even see the problem by analyzing the output o...

Hi Alex, Thank you for this prompt reply to a non FCWii man I have also uploaded a video. I have just noticed that my radio is not perfectly centered... I will have to add a "deadband" around the neutral points. I can't imagine that the drift is due to the 8g ... My quad is drifting just w...

After a bit of testing, I really do like this option This would be my final suggestion... Use currently unused "level D value" on the GUI /LCD setups to control the max rotational speed in returning to level ..... replace PTerm = (int32_t)errorAngle*P8[PIDLEVEL]/100; to: PTerm = constrain...
